Are you kidding me? Seriously now.
To the OP: I don't want to sound harsh or discourage you here, honestly, I want you to be able to do things the right way. Usually don't touch posts like this with a 10 ft poll.
There are quite a few issues here, this is
not good... a PK/13/14 booster?
For real?
Obviously there is some lack of preparedness here. This seems like the root cause of the problems, and many people have this issue. First of all the lighting you are using is not intense enough. Four tube T5's are great for starting seedlings, early vegetative and side lighting. This is more than likely why the leaves are curling as they are, and you can see some of the lower growth in the dark has wilted near the point of death (it might as well just be removed). Plants are stretching due to the lack of light, buds are evidently very airy.
