What do you suggest I do? How many more lights should I add? As far as soil, I don't know what else to do. Everything else around here is terrible potting soil. I had previously tried the Scotts hyponex but that stuff is so wet in the bag already that it molded in my pots overnight without me watering them and when I went to look inside the bag, everything in there was covered with the white fuzz as well. That's why I tried making my own
Actually, the white fuzz isn't bad. That is the soil activating and the bacteria going to work. The bacteria breaks down nutrients, especially the cheap nutrients that arent already activated and ready for the plant to uptake. Not saying Scotts is good soil, it isn't but it is OK if it doesn't have the time released nutrients mixed in the soil.
As far as what you should do, for me that is tricky, especially since you have already started LSTing. That will make it difficult to transplant. If you take out the degree of difficulty, I would..
1. transplant into better soil, in a planter with plenty of drain holes, mixed with perlite, all the way to the top.
You want it to be as deep as possible. Deeper is better than wider. If you only fill your planter halfway, you will find yourself rootbound in no time.
Rootbound will cause such problems as stunted growth, increased stretching, small buds/yield, wilting/yellowing leaves, etc.
2. Get your cfl/flourescent lights within 3 inches of the plant. CFL/Flourescent need to be sitting right on top of the plant to penetrate down it. As it grows, you will want to add more CFLs on the sides to penetrate as well, also within 3 inches of the plant. At the rate MJ grows, you will find yourself moving the lights constantly to keep them within 3 inches but not touching. HID lighting is a much better option, but comes with it's own challenges.
3. STOP misting the plants. You only need to do that at first to help get them started and rooted.
I am not sure if the yellowing leaves is a lack of nitrogen or just from overwatering. Overwatering is certainly an issue but it is possible you have a nitrogen deficiency as well. Problem is you don't want to overdose it on nitrogen if it is entirely caused by overwatering.
If you do transplant it, whatever soil you use will have enough natural nutrients in it to last for a couple of weeks.
If you choose to not transplant and try to push through with what you have, then you need to be careful with how you water it.
Let it dry out until the planter is light before watering again, and don't mist. Keep an eye on the new growth. If new growth continues to come out light in color then add nutrients on the next watering.
