my AK-47 hydro is in trouble. please help!

I have 9 AK-47's and 3 Critical mass. (hydro) They are two weeks old. About three of them are yellow starting in the center of the new growth. I picked up one of the cups and there are a couple of small roots coming down. on the longest root is black at the tip and turns to brown then to heathy white. NOT GOOD!! I have them on half a dose of Maxy grow. Do you think it's to much food or the PH? Don't freak on me but I still have to go get a PH tester witch i will do tonight. where do i go get a cheep one of those? Please Please help.

I would say try moving it to a bigger pot.

good luck

id say root rot possibly, seeing black and brown on your roots aint good. In hydro you want your water temp to be 65-68, and everything needs to be light proof. Address those things while added h202 to your solution, think its like 1tbsp per gallon of 3% but look into that. good luck

Thank you for your help. It was the temp. PH is good. I just needed to cool down the room with a intake vent. Now all the baby's are nice and dark green and on the full dose of Maxigro. Third week and second stage growth is coming in. It's going to be a nice crop.:jointsmile:
