Room temperature 70 to 80, RH 55 to 65, I can take light reading when I grt back home, but I think my dumbass had my meter set to TDS and I just over did the nutes based on manufacture recommendations, I changed out water and rePH'd gonna let them set for 24hrs n use up any left over nutes on...

Forgot to add rusty/brown spots are old and stopped progressing after clorox treatment/flush, then adding hydroguard with new nutes/res change

Everything seems to be moving in the right directions, plants have began making noticeable gains in growth but this morning I noticed a discoloration on some of leaves. Could this be due to the new nutes? EC 1.7 Ppm 900s Ph 5.6 to 5.8 (swings from 5.5 to 6.0) Water temp 62 to 68

ppm, ec and ph is holding steady, Temps are stable and it seems after a clorox treatment the spots have stopped spreading, I trimmed bad/dead leaves to expose new growth will update in a few days

Maybe I'm an idiot but I just thought of something, could it be from my humidifier? I noticed a white residue on my humidifier this morning, where it sprays out, quick Google said its excess minerals the filter didn't pick up. The plant that's most heavily affected is closest to it and the least...

Ok thank you I'll give that a shot and keep you posted

Yeah the actual draw is alot different that's why I picked up a second one, should've just paid a little extra for better quality but hind sight is 20/20 lol. They were actually doing real well until I started adding nutes, I had the light set at about 26 inches, if my memory serves me right...

@Ed Rosestale I missed part of your response im sorry. My lights are both set to manufacturer recommendations 18 inches from canopy, I'm running a 1500w and 2000w Blurple from KingLED. I can get actual readings for lux, par etc etc if you'd like but when I set them they fell within range and I...

I think we read the same posts, unfortunately after I started and bought the foxfarm nutes. Yes I grew them from seeds and I would start more but I'm moving a few weeks after these would be harvested so the timing worked out running auto's over photo. If she dies I'll take my licks and lessons...

That's what I was thinking so I ran FF CalMag it helped a bit then they tanked again and the brown spots spread to new leaves. My base nutes are the foxfsrm trio but I have floraflex on the way and will flush system completely before I start the new line. Should've just bucked up and got them to...

Thx for the reply, when I was feeding I was at 380ish @ 700 scale. Yesterday when I flushed roots were nice and white no slimey feel, today just discolored still no slimey feel. I was worried by the look of my leaves that it was a possible CalMag deficiency so I added that the first time and...
