Hey guys and gals…. Yet another issue, I’m sorry to keep bugging… Seems I can’t go a week without everything going to shit. So 10 days ago or so I did a full res change and it was a complete disaster. Long story short plants are alive but I feel like they are dying… basically I had them in fox farm trio with ppm @like 1700 for 3days before realizing, tried getting lower added water etc only got down to 1100 ish… so the upper leaves started to turn brown and rusty color again leaves dying etc. I did another full flush letting them sit in h20 no nutrients for 24 hours then added nutrients and ppm down to 500 for a few days and then 700 and now 800 or so… plants still look like death and I’m quite worried.
Also got a new hlg320xl 2 days ago it’s hanging 21 inches above the plants.
Tips now curling, browning, some crumbling to dust at touch… what do I do!. Is it light burn? Could it be nutrient burn again even a ppm of 700s? Is it too dry? Doesn’t feel hot at all at the leaves…
Thanks for any and all help everyone!
