Do you use cheap Chinese ph meters? Im not sure how accurate they are but if they are cheap I think this is part of your problems. I highly recommend you to buy canna coco profesional + and canna coco AB basic nutes. Use your tap water and their light feedeng schedule. Start fresh with seeds or clones. Wait new ph meter and post your reading.
Or house and garden coco nutes, they're really hard to stuff up, or at least they were. When I first stared I was feeding at EC 3.6 for weeks without any sign of burn (didn't realise I was reading ppm instead of EC). Either there is a whole bunch of nothing in their nutes or it's unavailable to plants or something strange, but plants grew really well and turned out great. Not to mention it put my ph right on 5.8
Then I stated using fulvic acid with it and was getting tip burn at EC 1.6. Figure that one out...

The PH meter's name was ADWA. It was relative cheap. This is hungarian brand and made in Romania. Then i buyed Milwuake and last just 1 month... It was relative cheap too. Tomorrow will arrive my new PH meter. Hanna HI 98128. This is a combo pen. PH and EC. It cost five times more than Adwa or Milwuake.
Thats because most of us is illegal growers leaving in fear. With small tents without decent genetics and this 4-5 plants from seeds is all we have. If this 4-5 plants failed we don't have nothing for smoke.You guys are over thinking all this shit.
