My Baby's Looking bad can someone advise

I have a bud box 1.2 meter sdquare tent using 2 600w lights a 6 inch intake and 4 inch outtake. My baby's are in an amazon areo system.

The problem I am having is over the last 4 days my leaves are going yellow and drying out (See pics attached. I have changed the water yesterday and lowered my nutes to 1.2 - 1.4 ec. I think it is a ph problem and may of gone to low. I am currently asjusting my ph to 6.0 over today. Hopefully this will help but any ad

vice would be great. Ps if by later no improvement i will be putting on plain ph water to try solve problem.




Ps pictures all of sam leaf but under diff lights. It is mainly most the plants leaves covered except very top leaves

That looks very much like a nute deficiency caused by an off PH-value. I bet that's your problem.

do you sugest leaving it on low nutes and keeping eye on ph or do a full water flush with clean?

anyone? help me

I would adjust PH-value and hopefully see improvements within a week.

yup, looke like a ph problem. get it in check. Do you have an ozone generator?

yep...ph is off. get a reader and check the ph. hold off on ferts till you get things straightened out or use @ very low strength if you know they need them.

Ph. Glad we are all in agreement. hydro/ aero you want between 5.8 and 6.3. LOL i dont care what the bottles say on them. any higher or lower and I always see deficiencies.
