Im not familiar with the lambert but it looks fine to me. I only use mycos in the hole at transplanting, spray it good with a mister bottle and be sure it comes in contact with the roots. Personally i dont apply any after that. Your past that now so dont worry about it.
Dont be nervous about the mollassas, roll that bottle over and read the ingredients, lots of calcium, mag, phos, and everything else thats important. Some say certian nute companies rebottle and rebrand mollassas with few if any additions. I dont know but i can assure you it wont hurt the plants. Tablespoon per gallon for now.
Get that T5 down with in 1 to 5 inches of the tallest plant, block the short ones up to that level. It encourages root growth and lateral distribution of the cannopy. They'll be fine. You cant get the other grow lights right down on em like that. They say the light is the food and them t5s arent all that strong, so to realize maximum gain they need to be close. Also pile on more soil, right up to the bottom leaves, keep doing that till the pots full. Are them 3s or 5 gallon pots? Think tomatoes, you lay them over or their side and cover the stem clear up to the top and they grow roots along the whole length, roots good, root good!
When i look at them babies i dont see big problems, what i see is plants that had a rough start, evedinced by the crappy lower leaves. Then i see new good looking growth above the crappy and if you just transplanted outa that poision soup you had going just a day or so ago, id be damm happy with where your at.
Trust me, you aint out nothin, lower the light and water with the mollassas only for a couple weeks. Keep pictures coming, about a week apart then we can all look at where you been and where your at then. Im hoping some of the real experts'll chime in and teach us both something?
Heck you gonna be entering em in the state fair in a couple months!!
P.s, thanks for letting me come along with you on this!
