It's best to add new nutes for your next grow. that way you have something to compare and you can get a better answer. Nice setup you got and your babies look nice. I am tuned in.
It might be your ph is off from your nutes. I had the same thing happen to my baby. During the vegging she was fine. But than i added tiger bloom fox farm nutes and on a few of her leaves i saw rust like color on them. 30$ if you got it. Digital ph tester Ph test kit
Yea my camera is Toshiba-PDR-M60 so i can't get a hd picture. Anyone know of a quality camera 50-100. Also is there stuff around the house i could use as Ph up and Down? or do i need to buy the ph test kit?
