Indoor weird leaves?

[shimmz22]

Hey all, currently started my autoflower grow and am about 3 weeks in and have noticed leaves on one of my plants turning kind of light green and having a weird look to it. I am growing in OF soil and have so far givin them 2 feedings of Pure blend pro only small amounts(4ml per gallon). Anyone have any thought of what this could be?

I agree with TBM, they look over fed. Also, I'd suggest you take pics with the lights out or move them from under your lights. Seeing them in their natural color makes it easier to see what's going on with them.

I USE HAPPY FROG INSTEAD OF OF BCUZ I ALWAYS HAve some kind of nute issue with ffof. sorry bout all the CAPS. ffof seems to be less forgiving with any nute regiment. either way unless ur using some thing like pure pro mix theres no way 3 week olds need any nutes. i suggest a good flush.
