One more thing.....any idea what these blotches on the leaf could be?

The beginning of a calcium deficiency, probably caused by heat. Judging by how curled your leaf edges are, I'd say your temps are too high or humidity too low (or both). This causes the leaves to evaporate massive amounts of water to stay cool, which causes a domino effect with nutrient availability.

How do I increase humidity then? I've run a fan right around the leaves now so temp should be alright hopefully.

nvm, I was just being too lazy It was probably because of the heat cuz I just put a cfl light very close to the plants for side lighting. I'm looking out for calcium deficiency too since I'm growing in coco and waiting to finish the nute solutions before I change to coco specific nutes.

Couple things; I should have clarified that there are other potential causes for the raised leaf margins, one being wind burn, so watch how much air you blow directly at them. Also, coco has high levels of potassium and tends to be prone to Mag deficiency, so you need to adjust accordingly.

Not to sound rude, but you'd probably get more help with this sort of thing if you go to the "plant problems" forum instead of the advanced section. Just sayin'.

Understood, I made it in the advanced section cuz of the topping thing in the beginning. There is such a thing as wind burn??

Yeah, I really don't mean to come off as rude in any way, you'd just probably get more help is all. And yes, too much wind creates a lot of the same effects that high heat does, it makes the plant transpire more water from the affected leaves too quickly so the edges curl to try to slow down moisture loss. You usually end up with a calcium/magnesium def in that particular area when that happens. At least I do.
