Hey bro plants look good. Nice job on the cloner too!!! I did some research and found out that I did not nute burn my plant at all, its a Calcium deficiency I had with my Jack Herer. It kind of looks like yours too, especially if they are flowering....You might want to get some Cal/Mag for your girls. I could be off too but thats what I would say from the looks of the pics. Now if your using nutes that has Cal/Mag in then you might have a pH problem in your soil cause it could be blocking it out. Or I could be completely wrong but someone should be able to help. If not then go post something on Marijuana Plant Problems you dont want it becoming a problem in the near future. Hoped that helped.
Here is some info on them:
Calcium (Ca) is fundamental to cell manufacture and growth. Soil gardeners use dolomite lime, which contains calcium and magnesium, to keep the soil sweet or buffered. Rockwool gardeners use calcium to buffer excess nutrients. Calcium moves slowly within the plant and tends to concentrate in roots and older growth. Consequently young growth shows deficiency signs first. Deficient leaf tips, edges and new growth will turn brown and die back. If too much calcium is applied early in life, it will stunt growth as well. It will also flocculate when a concentrated form is combined with potassium.
Manganese (Mg) works with plant enzymes to reduce nitrates before producing proteins. A lack of manganese turns young leaves a mottled yellow or brown.
