ServingSize's First Real Grow

After three grows of Northern Lights x Haze in a closet with no fan, no ph meter, dollar store bags of dirt, plastic pots, under under 125w total of CFLs with only two being 2300k,(Lol right?), and literally the only thing going for me being good genetics and Technaflora Recipe for Success, THIS is going to be the journal for my first real grow.

My setup which I believe to be a very cheap and efficient way to set up a grow room is.

2x4x5 PVC frame coated with Black and White Poly Film, cut to fit 240CFM fan which is ducted to a 200CFM 6x10 activated charcoal air filter. - Total cost $40 for filter (I'd probably buy a little more expensive next time, but we'll see how it goes), under $20 for all PVC fittings, $25 for Poly Film. Total for complete tent with ventilation = $85.
400w Plusrite magnetic Ballast and 400w Plusrite HPS bulb. $37 and $10 respectively. I didn't believe it either.
Fabric net pots, $15 for 10.
Black Duct Tape = $5
Total cost including shipping for 400w 2x4x5 grow tent with = $177. Not bad methinks.


Now on to the grow!


The medium this time is Van Kempf Coco Coir, expanded with 1tsp/gallon Magical. (I forgot on two, oops!)
The strain is Speed Seeds AK Automatic and one BlimBurn Ak Automatic that was a freebie.

So far I started feeding them at the third set of leaves and gave them full strength vegetative nutrients:
15ml B.C. Boost
7.5 Ml B.C. Grow
5ml Sugar Daddy (just switched to Blackstrap Molasses) the last two days of veg when i ran out.
2.5ml Magical.
1.25ml Thrive Alive B-1 Red
(per gallon)

This was applied with every feed once a day as I've read many do with coco. They seemed to be loving it right until right about five days after this picture was taken, and then one out of four showed signs of N. Tox in the form of leaf clawing. Since then I've fed with 1/2 strength veg formula once:

7.5ml B.C. Boost
7.5 ml B.C. Bloom
2.5ml Magical
1.25ml Awesome Blossoms
1.25ml Thrive Alive B-1 Red
5ml Golden Barrel Blackstrap Molasses
(per gallon again)

And they've been drinking for about 40 hours. The next picture I post will be of the plants tonight, and I'll post it in a few hours. I'll probably feed again tomorrow in the morning.

The light cycle was 24 hours for the first two weeks, and then 18/0 when I remember to turn out the lights (about 90% of the time).

Please post any tips, tricks, questions or suggestions you have. I'm here to grow my plants and grow as a grower. I'll post

Switched nutrient solution to
5ml B.C. Boost
7.5ml B.C. Bloom
2.5ml Magical
1.25ml Thrive Alive B-1 (whichever i have more of)
2.5ml Awesome Blossoms
7.5ml Golden Barrel Blackstrap Molasses


This ratio has higher P and K, B.C. Boost was lowered as it is the largest source of N and bloom was kept the same.

First problem today. When i turned on the lights one plant had a yellow wilted looking leaf and two plants had blotchy yellow spots, uneven yellowing I would call it on lower leaves. I think it's a P or K deficiency and I've continued feeding a higher ratio of PK to N. Hoping for the best.

Well seven days have passed since what I thought was a P or K deficiency, and I've learned a lot since then. It definitely wasn't just a P or K thing. Found out that my tap water I've been using has a pH of 8.6, so I watered each plant yesterday with 1.25 gallons of 1/2 strengh nutes + 1/32tsp distilled vinegar to pH until my pH meter and pH down get here. Also watered again today with 1.25 gallons each. All had heavy runoff both times and growth seems to be picking up, so I'm hoping for the best. I did take a few more leaves off today but I'm hoping they will be the last ones to die.

Everything's looking good :d. pH dialed in at 6.1-6.3 after erroneously pHing to 5.8 because of some bad advice. pH of 5.8 just exacerbates the calcium and magnesium problems of the medium. About three weeks left. Five weeks until I have to cut because of housing reasons. One plant looks like it might need the full five weeks.
