I'll be curious to hear if you were able to turn this around, or if it continued to progress. This happened to my last (and first indoor auto) grow, I have some hypothesis about why, but I'm not positive. In my case it started at around 5-6 weeks in and continued to progress all the way until the plants barely finished.
My guess is ph issue. Haven’t gotten the blumats dialed in with this current run
wow she is beautifull
Hey Dude.... that smacks of P defc.,... is it mid-->upper zones of the plant?
LOL
Just mid zones from what I’ve seen, only on 2 nodes in the middle of the plant. No spread since that photo was taken. Sharing a 65 gallon pot of coots mix with 9 other plants lol. No nutes, everyone else in the pot is doing fine (to varying degrees lol). No one else is showing such a dramatic issue. Since the spread has stopped I stopped worrying about it for now. My blumats get air in the lines sometimes which makes the soil dry more than I want, and then wetter for a bit. I do a weekly compost tea with barley, kelp, neem, and maybe a couple other things but no sugars, plus a source of microbes.
....next thing to grind out is if it's a simple lack-of, pH lockout, or antagonistic uptake issue... or combo!
Usually the first hang-up is getting a solid in-pot pH reading, not run-off which is crap for this job.... a soil pH probe is the ticket!
I need nute info: brand, dosage, frequency,... medium type,....water quality factors in too (hard/soft = ppms; pH)... You're on a res'?
Greenhouse is empty til june lol, otherwise they start flowering
