So I’ve been struggling with nitrogen and cal/mag deficiencies. Reservoir PH 6.8 and soil 7 so kept adding more nutrients but kept getting worse. Luckily I stumbled across an old post on another forum of someone saying they’re PH probe was way off and they cleaned it with wire wool and a Brillo pad. I did the same, root zone PH 5! So I knocked up some 8ph water and flushed, managed to get PH run off to 6.4. The run off smelt really bad so mixed another PH 7-8 and added Root Ex and Planacillin. Flushed again and run off is 6.8. I’ll wait for pots to dry out before starting them back on nutes. Lost a lot of grow time in flower chasing ghosts. Remember kids always calibrate/clean you’re tools. Looking forward to a good last few weeks. Thanks for stopping by ✌️🏽
