Lol, exactly. Why though?, 1.2 ec to much? More cal mag, led 2.5 ft off canopy maxed out touching ceiling

I was looking at some other posts on advanced nutes (I've never used them). That stuff packs a punch and a lot of folks are using it at 1/2 strenght and some even lower.

I go from 315 lec in veg, ec same around 1.2 , then to the gavita 1650 led in flower, seems to be the same story everytime. Tried raising temp and humidity, because that is what is recommended with led, but still same problem

Yeah, definitely see some similarities, I could certainly cut it back, but these are large plants and they take the 1.2 ec in veg it seems no problem.

So I would say this moving forward (too late for this grow). Next grow start super low with the nutes. Even to the point of showing begining defficiencies so you have a good idea were that threshold is. Then just bump it up slightly from there and keep it there until if/when the plants show a need for more. That way you always have a starting point that if anything shows up its 99% deficientcy and not toxicity. Soooo much easier to diagnose that way. For hydro anyway.

No I never have, I run single 5 gallon bucket dwc with advanced nutes for veg also, dump bucket and mix fresh once a week. It's ph perfect so I just leave it until Sunday. It seems to be something with these led lights I think, it's been an ongoing problem for the past like 18 months, can't figure it out. Shortly after I move them to flower room under leds they go down hill fast.
