MY PROBLEM: very slow growth, aprox. 2.5 inch tall, purple stems, somehwat pale leafs especail towards outter tip, and very very tiny brown spot on ridge tips of new growth leafs. at first start i was using ph test strips/and ph test solution to check ph. after seemly vague results i purchesed a digital ph meter. to find out my ph was ruffly a point higher than prevous methods were showing. after germination seedlings went into setup and res. was ran for 14days then did water change and then started 1/8th stregth nutes,super thrive. so from reading in my grow bible i have what i belive to be sulfer defienceny. due to too high of ph???? so hope the res change will correct the problem? ill try to figure out how to post sum pics asap.

To the top as I would really apprecite some input here

 

[OG13]

It take a while for seeds to grow, relax. The roots need to get established to have growth on the topside. I like to start them in something else to make sure you got a good rootball started before you stick them in hydro. You got sulfur and mag in your water, no need for epsom. Are the plants getting water to the roots and is there a bubbler in there? They should have all they need in the seed for the first couple weeks, you don't have a def yet.

 

[basementdwell]

ur rh is too low and 65 deg light off is too low IMHO with seedlings bump rh to 60 % and temp to min 70

 

[Kush Killer]

Thanks forthe replies, the leafs just seem curled more than they should be, but if yu guyssay I'm good I take ur word for it! Thnkx and ill get my RH and lights of temps bumped up aa bit.

As far as ph being to low....??? 5.5_6.5 is where I wanna be correct? I'm within that range and usual shoot for 5.5 when adjustin ph. I'm gonna switch to a 50/50 ro/tap water mix.

 

[Kush Killer]

Also og yes I have a pump with feed lines goin into my rockwool untill I have a established root ball touchin the water. As for bubbles I have 2 air pumps feeding 2 14" airstones and a 2" round airstone so my bubles are great imo... goin to get some ro water this week for res change on saturday

 

[Kush Killer]

got humidifier in last nite so shes running high 50's low 60's on rh%, as well as bumping nite time temp a few degrees.. also grabbed some "white widow" root stimulant as well as "humboldt roots" stimiulant and some" prozyme", also got my replacement MH bulb.. but i think ill wait a week or so to put it in????

also had one other question inregaurds to my water.. should i let my tap water sit out for 24_48hrs before use?

 

[Kush Killer]

So its normal for my leafs to curl ad twist a lil bit?

 

[basementdwell]

yes let the tap no ro h20 sit 24-48 hrs to allow the chlorine dissipate. curl ? IDK can u put covers over the net pots ? like a pint glass. I always let my new seedlings sit in the humidity dome for a wk or two till i have my first set of 5 leaves. the humidity really helps with leaf development.

 

[Kush Killer]

yea as you can see in the pics, they curl under or downwards and kinda twist a lil bit.. i have my rh bumped up to low 60%'s... and tempos are bumped up aslo about 80 lights on and 70 lights off. ill swingby store after work and grab sum clear plastic cups to try out as humidity domes..

 

[FrankFoster]

keep in mind that you already have a dissolved solids ppm ceiling of 500 ppm out of the gate. So you need to calculate that into you fertilizer additives.

The 1/8 strength is about right on, right now. when the plant has a bit more room to breathe, you should check yourself at 1/2 strength.

Also your water requires a bit of citric/phosphoric acid to it when you mix it up so that you can ph to at least 6.0.

I bet with careful ph control, moisture, and aeration, you could get her to go a long way without nutes whatsoever. water changes only... lol.

My first impression is it was treated to a a bit of a "HOT" mix...

 

[basementdwell]

curl is the nutes, i did it to my current ones as seedlings. seeds are good on their own till 3rd set of leaves. (1st=3/,2nd=first set of 5/ 3rd=second set of five) then u can feed 1/8 strength. its usually two wks since germ. look at my current grow in my sig line

 

[Kush Killer]

Well update.. stems are strating to turn green and. Leaf growth is prgressing I think bumping the rh up has really helped! Ill try to get a new pic in the nxt couple days.

 

[Kush Killer]

Also was curious on the humidfer, is cool or warm mist better?

im on week 5 since i planted with a 3/8 tap root... they now have a set of 3leafs and working on their first set of 5leafs.. for some reason this seems slow to me? like they should be a lil farther along... i think right now my biggest problem is keep a consistant temp... BUT i have something on the way that should help me get things exactly where i want them to be day and nite..

 

[basementdwell]

either cool mist or warm doesnt matter other then the warm tend to build up condensation where the cool doesnt IMHO. nute over dose stunts them a tad. You got 3 leaves and running light 24 hrs on ? have ur leaves straighten out ? and other problems ? yea hell of a time tryin to keep my heat in thank god i am almost done

yeah ive got a set of 1 leaves, a set of 3 leaves, and the first set of 5 leafs is JUST starting to make a apperance, i have no branch grow over all height is about 2" and diameter of plant in hold is for sure no bigger round than a quater.. im running a cool mist humiodfier now so thats in check! running consitantly at 60%, ph seems to float up half to 3/4 of a point a day.., the wierd thing is and you see in the pic i post later on today, that 1 plant looks great imo other that being small, the other 2 are lighter greeen in color, and leaves are still twisted a bit and curled, my other one looks good jsut seem droopy.. the ONLY thing i can think of is my climate... ive found that im having trouble keeping it consistant! lights on is acutally in range of 70-85 at any giving time, and lights of temp is running at a low of 64-72 degrees.. i can pin point exact when these temps are occuring, so i decided to purchase a senntenial evc1 in hope it will help me regulate the temps. and once things seem to level off and the grow is flowing smoothly i can incorperate c02. oh and basementdwell for tryin to help me out here. oh and im on 18-6 light schedule.. should i be on 24hrs? will that stress em even more switch back to 24hr?
