85 for veg is high Imo
roots are stained with nutes(brown) otherwise healthy, rez has no smellWhat do the roots look like? How do they smell?
at 4 weeks veg in my opinion you need to bump your feed levels up, 300 is way too low that far into veg. Your ambient room temps are fine. I don't see any mention of water temps. what are your rez temps running at?this my first grow in rdwc, ive grown in dwc for past 2 years with no issues. Plants started slow and continued to grow slow, im in veg for 4 weeks, now my lower leaves are yellow and a few are wilting, i believe i had nute lockout so i flushed system and reduced ppm to 300, plants still dying, i dont understand whats happening.
Using maxigrow expert schedule.
ppm 310
water temp 68-72
ph 5.8
room temp is 78F
78 is fine, lower would be better but running 78 has nothing to do with your yellowing leaves condition. they are hungry bro , any pics????this my first grow in rdwc, ive grown in dwc for past 2 years with no issues.

And in a way you confuse me, on one hand you say lower growth is yellowing so you flush and then cut back your nutes???? Bump up your nutes and watch for a week. Keep in mind that yellowed older growth wont restore itself. Watch for changes in the upper/newer growth once you get your nute levels up. just my .2cents
my room isnt sealed for c02Thats why I said imo we all grow different tho. I never ever run over 80 without Co2 veg/bloom
plants do respond well in igher temps, and as you said only can tolerate with co2 supplement at higher temp ranges. But 78 ambient isn't all that bad...…….. I have gown killer weed in higher temps and no gas!!!!Thats why I said imo we all grow different tho. I never ever run over 80 without Co2 veg/bloom
that can be an issue, so if that's the case work on getting your ambient temps down. Sounds like you have water temps in hand…….. I always used a chiller in my rez. Never had any issues. So you have at least 1 part conquered!!!!my room isnt sealed for c02
another reason to not believe everyting you hear. Was growing hydro before counter culture evn exised 300 ppm that late in flower is too low. Try what I suggested and thank me later!!!current culture describes my condition as nute lockout, both remedy was to reduce ppm. Also current culture nute schedule is 300ppm in late veg
current culture
I just flush whole system and started over but with lower ppm
water temp runs 68-72 with 1hp water chiller but the drooping plants are still sickly
never had issue in dwc, this new system is ucdwc, shouldnt be that much differant, main difference is the undercurrent, is there such thing a too much current?another reason to not believe everyting you hear. Was growing hydro before counter culture evn exised 300 ppm that late in flower is too low. Try what I suggested and thank me later!!!
