All I know is hydro. Have never done a soil grow. Used to grow ebb and flow on a much larger scale. My current grow is in a micro stealth cabinet, and a small dwc was the only hydro system that would fit/work...but obviously this small system is harder to get dialed in compared to my old E/F...
Appreciate the reply. My temps aren't a problem. Rh is a little low(40%), but am installing a new humidstat this weekend so that shouls be resolved in a few days.
Going to start raising nute concentration and see what happens.
Usually waited about a week or so...enough time for the next set of leaves to grow in and see that my changes made no difference. Roots were white in sterile(bleach), slight staining from nutes with hydroguard. Never any slime or funky smell.
I should note that, aside from my 3part nutes...
The peeling paing on my rez looks like shit but it'll work for now. Small/micro DWC. Ph 5.5-6.0. Running AN 3part at 100ppm in RO water. 18-6 lighting. Rez tems 65F.
I have no idea whats wrong. Had this same issue with my last grow(same strain). Spent the entire grow trying to figure out...
I'll likely give that a try. I upped the nutes and new growth looks good. Too early to tell if that was the fix since it usually takes a few days for the spots to show. Either way, I'll be switching to bleach in a day or two with the next res change. Thanks!
I currently use diluted pool shock. Added every 2-3 days at a rate of 4ppm(based off initial dilution and reservoir capacity) Roots look healthy and white. No slime or funky smells.
Flushed and ran at 0ppm for 2 days, then slowly increases to 100ppm. I'm mainlining so its been topped twice and lollipopped below each top. Same the keeps happening...new growth looks good. Next node grow in, then brown spots start to show on older fan leaves. This is followed by leaf...
Greetings....not not sure what I'm up against here. Any advice would be appreciated:
Strain- White Widow
Small cabinet DWC.
2 weeks into veg.
Cal-Mag at 100 ppm, GH 3 part at 200ppm.
Ph 5.8 and very stable.
150watt led panel set at 50%
