I thought I might go over some super cropping techniques. Please remember certain strains respond differently. I will be using a Perma frost as my example plant. I didn't have a perm for the first example so I used a store bought Thin mint cut (2pics). Water bottle is for height comparison...
IMO it comes down to the grower if your mothers are well fed. The babies will expect a similar treatment. It does not hurt to feed a clone they just need very little food. If your mom didn't feed you when you were a baby you would grow slower and possibly get sick easier because you don't...
I would assume its the food. try some vitamin B to get the plant to focus on the roots. After you have roots you can start feeding again lite that would be my suggestion. Little burnt little stress they should be ok.
Looks like you may be over feeding them. If I am reading correctly 700ppm? appears to be a little high. It looks like the larger ones are doing better but being over fed. Are you feeding the babies the same amount?
Yes this is true but a new grower that cant read the plant and has not built the plant up for this feeding plan will not have these results. I agree I feed the shit out of my plants and the worst that happens is a curled leaf.
You may want to take a pic with hps off. from the looks of it the burnt plants are a lighter feeder than the others. Pics would help. Possibility of wind damage. Do you have fans blowing directly on the bad plants? Flora is a good base it was likely the additives if not the wind.
