Hi I've been growing these 3 Feminized Grand Daddy Purps for almost a month now and a week or 2 ago now they've been growing yellow out of the new growth then slowly turns back to green with a little yellowing between the veins. Im growing in soil. The PH reading I got with PH meter says 5.5 - 6. I gave coated the top of the soil with dolomite like a week ago but don't see much improvement raising the PH. Ive got them in Fox Farm OCean Forest soil and Im using miracle grow for tomatoes. I flushed one of them to see if that would do it but no dice. I gave another one epsom salts to see if it was Mag. but no dice. I was gonna go to the pet store today and grab a PH kit to test the Run off water. I'm using tap water at the moment. Im about to switch from T5 to HPS and I'm dying to top theses plants but i don't want to touch them till this issue is figured out. Let me know what you guys think. Thanks again. Here are some Pics
