Okay so i started seeing signs of what i believed to be magnesium and potassium deficiencies, especially the magnesium. Maybe with some nitrogen burn also. A couple red/purple looking limbs and other characteristics i read about regarding to mag deficiency. I read that mag def' is the most common def' during flowering. I also seen where low ph can cause mag lockout. I checked my runoff ppm and ph. Ppm was lower than the feed ppm. Ph was super low.. like 4.0 - 5.0 range.. When i mix my feed up, the ph is pretty high, about 7.2 or so, therefore i would use ph down by GH to bring it to the 6.0 - 6.5 range.. Im using The ph perfect line from A.N. so i guess i shouldnt have been adjusting, even though the feed's ph was high. So a few days ago, i stopped adjusting the ph of my feed. It doesnt seem to have gotten any better. I dont know if its had enough time for me to see a change yet either. Im growing in coco/perlite with some peat, but not much. Im thinking that i need to flush with either straight ph'd water or ph'd water with very low ppm of nutes, then continue on as usual. Being that im not 100% sure as to whats goin on, i feel like flushing isnt a bad idea, unless my problems are actually 100% deficiency issues. Then flushing would be a bad idea.. Throughout my plants' life ive been increasing feed at signs of deficiency, they get better, then it happens again from getting bigger and hungrier every day, and i increase again. Thats worked well up until now. Theyre autos and theyve been flowering for a couple weeks now. I also added a bigger light to my tent, making me wonder if they are hungry as hell from the amount of light they are getting. Im tagging @Aqua Man because i would really like to know your opinion on the matter. Anyone's opinions would be greatly appreciated though. Thank you
