Looks like nutrient burn (too much fertilizer).

5ml pk warrior

Whats your ph?

I dont know. Havent got a ph tester

Ok thats not so good. Proper ph is very important, especially when growing in coco.
Roots has a hard time absorbing nutrients when ph is out of proper range which leads to nutrient deficiencies and build up of fertilizer in the coco.
Try to find a cheap digital ph meter or ph test strips.
Ph should be between 5,5 and 6,5 when growing in coco.

Yeah man he's 100 percent right. Check the pet section of Walmart in a pinch.

Are you foliage feeding or spraying with anything?

Hmm well long as they seem to continue in a healthy path I wouldnt be too concerned

What's your soil.?
Can we see the rest of the plant? To me it looks like a defficency of something. What's the streingth of the nutrients your mixing and feeding with..
How often do you water/feed your plants..?
How old are your plants.?

I'm in no way an expert. But if your using limited nutes. Maybe this is more deficiency related. Looks to me as if its either calcium or magnesium deficiency . I read somewhere this can be a common sign around week 4 or 5 if grower isn't using calmag nutes. Certain strains more than others im sure. I thought nite burned started from the tips of the leaf and moved its way down. This looks more damaged towards the middle sections than the tips also leaning me more towards cal or mag deficiency

Will they fatten up much?
Using 600w hps

they look alright.
should fatten up, got, what 3 to 4 more weeks ..
what are the n.p.k. numbers on the a and b nutes?

what are the n.p.k. numbers on the the bottles?
they have a few weeks left so they should fatten up .. they look sativa'ish. what strain are growing? sativas don't usually get huge fat buts. unless they are hybrids.

5-4-3 and not sure what strain. Got 4 plants any chance u could estimate the yield

Id go with between zero grams and a couple few ounces per plant? I try not to get dead set on yield untill ive actually got to the point of harvest. Shit can turn sour in a days time and in some cases turn all your hardwork into having nothing to show for it because powedery mildew set in or mites came in right at the end or horrible nute burn yada yada.
