Manical Auto SOG: Organic Soil 315W CMH

[Crane]

My last (and first) grow ended prematurely as I decided to cut the plants down. I was in my 2nd week of flower and battling with all kinds of growth problems probably caused by a bad soil mix and too low pH.

My theory is that I'll have more bud almost as soon by starting a new auto grow. I have nine 1-gallon pots under a 315W CMH. The soil is now BioBizz Light Mix and I'll be using the same company's ferts. The light is gonna be on 24/7, as it keeps the temps from falling to 63F and even lower during the night.

I'm not gonna prune or anything,just letting the plants grow and finish asap. I'm running out of smoke here!

Oh I almost forgot, the strains:
- Kannabia "Baby Boom Auto"
- HSE "Bubba Kush Auto"
- Dinafem "Cheese CBD Auto"

Should all be pretty quick and not too big.

Day 5. Temps are 90 again, so warm outside. Every seed came up although I was hoping that maybe they wouldn't.

"What's that 10th seed?" I hear you ask. It's a Northern Lights Auto by RQS.

 

[Crane]

Day 11. Haven't watered them yet. One of the Baby Booms was a runt so it got pulled. Otherwise everything good despite the temps still hanging near 90.

Looking good, babies chugging along nicely.

 

[Crane]

Thanks Bob!

Here's day 15. I'm really happy with their growth. I watered them a couple of days ago with plain water, and added a little bit of milled malt to each pot.

 

[Crane]

Day 18. Everyone's showing pistils and stretching already. Temps are closer to 80 now as it's getting colder outside. They are looking quite hungry and I'll start feeding them with the next watering.

The Baby Booms (front row two left ones) are the most compact, and Bubba Kushes and Cheese CBDs are a little taller.

 

[Crane]

21 days. They are growing over 2 inches per day! Smell is getting pretty strong. I gave them their first ferts two days ago. Is it the 24/7 that makes them grow this fast?

Cheese CBD Auto.

 

[Crane]

28 days. Stretching seems to be done, except the Bubba Kushes. The BK's are the tallest plants atm at 20 inches.

I'm trying to keep the lamp height at 18 inches. I've had to raise the Baby Booms and the Northern Lights with some blocks. The NL is the only plant that's showing what I take to be calcium deficiency. They have gotten some homemade calmag and the NL got an additional 1/8 tsp of gypsum.

Gypsum is somewhat soluble in water/soil. You could make a worm casting tea for your nutrient deficiency. Just soak a cup of EWC in a bucket of water over night and water that in. Will be faster acting than gypsum. Have to be careful adding in calcium it can mess with the soil PH (not the gypsum) and do more harm than good.

Your leaf necrosis doesn't look like its the whole plant so maybe an isolated instance. AUTOs sometimes just get rid of leaves for some reason. You could drop your light down to 20/4 if you feel like it. They don't really require 24/0 lighting. Save you some electric and give the girls a rest for a few hours.

 

[Crane]

Heh, I can't shorten the light schedule as the closet temps go under 50 then so it's a little too hot in there with the lights on, and a little too cold with them off...

 

[Crane]

Day 36. Wee bit of yellowing on the lower leafs. A bit challenging trying to guesstimate a fert scheme to fit everybody.

 

[Crane]

Day 43. Not looking good for the most of them. Apparently I've been underfeeding them and not being cautious enough with the pH. Yesterday they got the full dose of nutes as prescribed in the BioBizz handout. Not much I can do but hope for the best.

 

[Crane]

Day 54. Everybody's doing quite ok. The Baby Booms have pretty big colas growing, and I don't know how much longer to give them? I have a x40 loupe for checking the trichomes but not nearly powerful enough for my eyes. So I'm flying by feel here when it comes to ripeness.

 

[Crane]

Ok, sorry for not updating for a while. I have pulled some plants already. One of the Cheese CBD's got pulled at 58 days because it literally had no leaves left, the Baby Booms and the NL went down today at exactly 9 weeks of age. They all had nice fat colas. The BB's are Blueberry x NL, and they have a delicious berry aroma, reeked up the whole house.... the photo is of the RQS Northern Lights Auto.

 

[Crane]

It's the end for this diary. I ended up with a poor yield of about 70 grams total. That's less than 10 grams per plant. The Baby Booms I would grow again, the others,not so readily. The Bubba Kush Auto smells nice and has the potency, but the high is a total couch lock body stone. That has it's place and uses but not too oftwn for me.

Well, onwards onto new challenges.
