Need some help please...18 daysbin flowering leaf color

Hey guys im 18 days into flowering with 2 600 wat lights leafs have weird colors on them im running hydro ph stays 5.7 5.8 always ..im using gh products

Hard to tell with the HPS's on they look fine to me but it's always hard to tell in pictures with the lights on . If you have yellow leaf edges at an early stage of flowering it could be magnesium deficiency especially if it's a White strain. Try adding a little bit of Cal-mag or Epsom salts, it won't hurt them, look for a diluted ratio for Epsom salts to add in on the net I can't remember the ratios. If your PH is going down allot you might have bacteria in the root zone and if that is the case I would run SM90 and peroxide combo, some people use pool chlorine but I can't say for myself if that works well. If PH fluctuates or swings allot that can cause weird spots on leafs. Make sure they're getting lots of bubbles too. And change out your airstones every couple grows. Old ones can cause bacteria and not to mention less dissolved oxygen.

If you are using one of those cheapo PH Pens (like I am), re calibrate it. My girls looked similar to yours. When I went to re calibrate my pen it was .46 off. I aim for 6.3 (soil) so I was really feeding with 6.76.

Yeah my ph is always bang on it never moves stay 5.7 to 5.9 solid always going to change nutes todsy and give system good ph water flush

Your plants look great keep doing what your doing. I have a feeling if you try to over complicate this your going to run into problems. The leaf in question in pic 1 is a sign of broad mites i believe. Those are clones your growing?

Yeah they were clones and yes had mite problems but thrre all gone now
