NuclearPyro New to hydro! Notice some white crystalline particles at base of 1st true leaves. Think it's residue from nutes. Planted 12/31/25 in rockwool

NuclearPyro All are 3 weeks old. Forgot to add calmag for 10 days bc i read not too, however, 100% needed for hydro... hence why there is rust spots on the biggest fan leaves. No problem with ph, just gotta get feeding schedule correct with the E.C. and TDS for there size. Overfeed once and caused nutrient burn(on small 1)( N toxicity on big 1s). I sprayed water on the leaves 1 hr before night and I think that is what caused the rust spots. Light burn, however after some added calmag and calmag foliar spray then plain RO water under leaves. They came back praying. Stopped feeding big ones, so lil 1 is catching up. I compacted the rockwool bc it was drenched(rookie move). Never ph'd the RWool either. 85⁰F, RH 85%, VPD .5 Survived harshest mistakes i made. But it took 2 weeks of constant nurturing to figure out mistake and to get on the correct course again. I wanna make it to the end and have some 🌲.

NuclearPyro Did a H2o2 bath to battle root rot of lil 1. Worst idea ever. He was doing fine. Found out they are autos bc they are flowering ar 5 weeks old exactly. Gonna be a low yield. But understand what to do now. HAPPY 🌲💨

No, autoflowers will flower when they want too, even photos if given stress and problems, need to make sure what you're running as both require different light hours You're running your light too close dude also dude, use a light metre with some normal paper. If you're having root problems with hydroguard its something within the system itself, hydrogen peroxide it at the recommended amount, same with your nets holding your ladies, dip em into the solution thats straight h202. You're lady will show signs of drooping, thats okay no matter what you do, youll see that from topping to whatever else. If youre not running a chiller you need too or youre gonna run into a lot of problems, look at my 4 to the other 2 with a chiller, I'm doing an experiment atm for myself to see why the upgrades are worth it. Cal mah issues with hydro are common, run a double dose always, it'll save you problems, look at the diaries
