The dropper tests aren't too accurate with water that has a tint to it. A slight tint yes, but the deeper color the less accurate it is. When you say the Hanna meter jumps around what do you mean? I'm not entirely sure what kind of advice to offer my friend but I'd still like to believe it's a PH issue more so than a lack of nutrient. Haven't you been feeding veg nutes for the last week and a half now? It's hard to believe that's a deficiency. I wouldn't feed "more" Grow Big although your plants show NO sign of nutrient burn at all, they are very lush green outside of the problem areas. Are they still growing vertically?
I'd get calibration solution and calibrate the Hanna meter, after you're sure it's calibrated, flush with 6.3 water. Also, when the plants are budding you can bring your nutrient ph closer to 6.2-6.3 to help a little. When you say "as close to 6.5" as possible, what is that? Above or below 6.5? The soil will buffer it regardles though. That's FoxFarms Ocean Forest soil?
well ive only given one feeding and that was a week ago of veg nutes thats it. other than that just ph'd water.
when i say close to 6.5 i mean this..
