LSL it is then. I just got tired of typing it over and over. Lol


Better lights should help, but low temps, wet pots that are too large, lack of fans and light and ca/Mg.Hey all first time Grower here and honestly I'm struggling a bit. I reached out to @InTheShed and he suggested to post here for some assistance!
I'm growing in 5fal fabric pots in a 3x3 tent in Promix hp with GH nutrients flora, bloom, micro just added Cali magic and supplementing with AH B52. Used Mycos during planting and repot. I am experiencing very slow growth at 30 days my plants are still at the 4th node hovering around 4 to 6" and have been repotted in the 5gal pots for 2 weeks now. Using tap water at 6.5ph and feeding most waterings roughly every 3 to 4 days. I was using cheap no name LEDs but upgraded to a Mars Hydro tsw2000 on Monday. I've also added two small fans to promote circulation and last night switched to 24/0 light schedule as my temp was dropping from 24ish to 16 celsius on 20/4. I will be giving a friend one plant this weekend and if required upgrading to a larger tent in hand if they ever decide to actually grow! Attached pics of plants around 30 days old and feeding schedule I've been using.
Problems
Twisted leaves (possibly from heat, had a space heater going at one point, no longer required due to high heat output of new light)
Clawing leaf tips (possible nutrient toxicity but light green colour suggests otherwise)
Lime green new growth and light green tint on most upper leaves
Possible Calmag deficiency on a leaf brownish discolouration
Crunchy dry leaves
Brittle stems - snapped one clean off and a few other split during light training and bending. Could be my inexperience though.
Sloooow growth!
New growth comes in very feeble and wispy especially on the sativa dominant blue dream plant.
Hey thanks farside, you are exactly right... that's what I get for not thinking for just a few moments before I ask a question.That might have been checking a Hygrometers accuracy, if I'm remembering right.
"The most reliable way to calibrate a hygrometer is the salt test. A cap (like from a gatorade bottle) filled with table salt. Add distilled water until just before it pours over and put that in a zip lock bag with the hygrometer overnight. It should be 75% in the morning.
Hey thanks Shed. Argh, oh well thank you all for putting up with me.... You all are the best around... Grow my friends grow.What farside (on the overnight shift!) said. The salt test is for hygrometers. When I actually used a pH meter I bought calibrating solution from Amazon.
Howdy DC! Don't sweat the pH of the nutes in ProMix. Did the shift in the plant health change with the new light? If any did, which problems are new with the light and which predate the change?Hey all first time Grower here and honestly I'm struggling a bit.

Not at all oops! You ask, we answer.oh well thank you all for putting up with me.
Your oil is a semi-solid anyway, so there's nothing settling out. The potency is the same either way. I bring mine to room temp so I can mix the sediment back in before I use it. It won't recombine when it's cold.I use my oil from solid fridge state?! Should this affect its potency?
Also, pick up your pots, if their all 5g in soil, they should weigh about the same right? Some strains can curl leaves with watering...I have a pair that do this everytime I move or water or they get dry. Are these photos all the same strain?
I thought the same thing. In pots that big, they can't use water every 3-4 days.I'm with nobody on making sure you have good watering practices, as wet substrate will prevent the plant from taking up the nutes it needs. Also, cooler temps will slow growth.
Question, are these autos is that why you are on 24/0?Hey all first time Grower here and honestly I'm struggling a bit. I reached out to @InTheShed and he suggested to post here for some assistance!

I am definitely riding the learning curve on proper watering and have succumbed to my anxiety by watering a little extra to try to get the plant growing. I filled an empty 5g with same medium so I can compare weight of dry using the lift technique. I let them dry out to the point of slight wilt when I first transplanted but since then have likely been watering a tad much trying to shove some Calmag in there lolHowdy DC!

I just switched to 24/0 last night and it wasn't to lower temps it was to keep them from going down to 16 celsius during lights out. I know low temps can slow growth so I wanted to eliminate that factor. I'm also hesitant to lower the light and turn it down. The plants are so short and compact as it is I could actually use a little stretch. I currently have it at 22 to 24" from the canopy at full strength.Question, are these autos is that why you are on 24/0?
If no my humble suggestions are to put that TSW2000 to 14 inches and dim the drivers all the way down and get to a 18/6 light scheadule.
Your temps are the same temps i get from being in a tent thats in a Canadian basement. Once your light is turned down, I doubt you will see temps higher than 20 degrees. Whatever temp high you stabilze at, find a Vapor pressure deficit humidity number you can easily slide into. In order to do this you need ventilation and the AC Infinity fans are incredible at providing you with a method of staying in a temp and a relative humidity.
Ease off on the watering and let them go to a complete dry to wet cycle...when the leaves point down they are pointing at their roots.
Perhaps you are locked out...It doesnt sound like you should be but crunchy leaves, twisted leaves, wispy slow growth are all things i experienced the same as you. I was ph locking out and I fixed it by switching to Peat based medium and Mega Crop nutes.
I am as inexperienced as you, maybe even more so. I have had a few "aha" moments. You will find yours too.
I use my lights in the winter to generate heat so I hear ya on that! 24/0 is fine in veg if you need it for heat, as long as you don't run them too close and stress the leaves out.I am definitely riding the learning curve on proper watering and have succumbed to my anxiety by watering a little extra to try to get the plant growing.

3 strains - blue dream, hash plant and a local strain called Torontonian cookies.
All of these problems have been ongoing and accumulating prior to the light change I'm hoping it is actually a trigger to fix them.

I go down to that too every night, Im not suffering and theres not a lot of photosynthesis happening at night. If anything it will bring out whatever funky colors your strain has locked away. If you want to warm your tent up, by all means run it full strength.

That pH should be fine for ProMix. I'm wondering if a flush and reset might be the best approach. Run 10 gallons of plain non-pH'd water through each pot, and follow that with a gallon of nutes at Early Growth strength. Leave off the B52s but leave in the calimagic. Keep the at least one fan oscillating at ground level and make sure the pots are off the floor.Ph is 6.5 after nutrients added sorry should've been clear there.
No photosynthesis is happening in the dark, but as long as you are giving your plants light, they're growing. Cannabis does not require a dark period to grow, only to flower.theres not a lot of photosynthesis happeining at night
Plants are on resin shelving racks above Rubbermaid tote lids upsides down. I shimmed the tote lids up to slope towards the door so I can shopvac the runoff out so no issues there.I use my lights in the winter to generate heat so I hear ya on that! 24/0 is fine in veg if you need it for heat, as long as you don't run them too close and stress the leaves out.
I'm tempted to say run a plain water flush through them to start over, but I'm concerned about how long it takes them to dry. Where are you in the feeding schedule in terms of amounts? N toxicity can lockout potassium, but calimagic is pretty low there. Why the B52 (other than great band!)?
Are the pots are off the floor on wire racks or open-bottom plant holders? Air circulation to promote even drying is important as well as getting them off the cold floor.
They all seem to be doing different things which makes a diagnosis more difficult.
Save the money on the Brita and feed them with tap water. Unless you're on untested well water, if you drink it it's okay for your plants. The standard flush is 3x the pot size but I don't think that's needed. I'm not even sure a flush is needed but sometimes it's easier to start with a blank slate.2L brita jug without the filter so it takes me awhile just to dish out a gallon or two!
I don't use the filter I took the top off I just use the jug for watering minus filter so it's straight tap water. It slows me down when watering as it only holds 2L and has worked so far. Thinking about getting a 5g jug and running a line and a couple valves for convenience though.Save the money on the Brita and feed them with tap water.

I would go between the Early and Late veg, and go with the full recommended dose on the calimagic. When I used cal-mag+ it was 5ml/gallon. Leave off the B52 for now.
Have you considered MegaCrop? You can even get a free sample to try it out. All the cool kids are using it, including me![]()
