not sure if this helps. but i have heard it a few times on this site and others. a little hydrogen peroxide or h2o2 then that can help keep algea in check. also as a rule of thumb i hear that the h2o2 actually increaases oxygen in the water and helps deliver it to the roots while in h2o2 form. so the amount, well these guys that do it (and do it in every feeding just about) do 3% per gallon. but they use like high grade stuff 35%, stuff you get at walmart is like 8-16% ish.
or something like that. i suggest you look it up as they also suggest putting on rotted clones and fresh seedling, some even recomend during germination (not sure if i would do that?). but this may help the health of your clones?
your ladies do look very nice. do you happen to know what type of genes? i mean is it sativa or indica? if i had to guess they look sativa but they breed so many different ways now that they take certain traits from one even though it is primarily the other. but are they primarily sativa?
those clones on the other hand. YIKES!! please tell me what you did as this is a scary thing. like damn man i see your setup and it's all cloning grade. i know you did everything fine that you posted. of course you are feeding plain ph'd water right now? right? see how old are the clones. you may be starting a nutrient buildup in the watter thus giving toxic levels of the vitamins and nutrientst that the plant is not using. you know, plants are kinda like at a buffet dinner, they take what they want and leave what they don't. i can't think of much else that could of gone wrong. maybe you had too many leaves? but it didn't look that different from the amount of leaves on others clones. by the way did you cut the leaves in half on all the clones? just wondering, it seems to be a rule of thumb to cut the leaves after cutting off the mother because it still gives photoprocessing but has less life to support since there is no root system.
