Still having issues with buringing and yellowing of leaves. I have fixed PH problem. (pen was 6points off..)
Also did a 1/4 feed flush for 2 days..
I upped nutes and started using epsom salts folier spray to help with mag diff. Its mostly the center plant (plant 3) that has the issues.
AN sets PH to 5.8 figure ill up it to 6.1 to try to get more mag.
