I need more information. What kind of water are you using, what kind of soil are you growing in?
what is the exact ppms that you’re feeding your plant?
what size pot are they in?
What’s the temperature and humidity?
Walk me through your feed. What are you using and how much of it exactly if possible. Don’t leave any information out on this I want to know exactly what you’re feeling and how much of it
Growing in 5 gallon dwc. Ppms have been between 450 and 500, until the night before last I did res change and bumped them up to 604. Temp and humidity just started running a little warm, 77-79 degree lights on and humidity is 61-65 ( dehumidifier will be delivered on Tuesday). I’m using well water which has a ppm of 42 by itself.
Unfortunately I don’t have a clue about dwc. I don’t know how it works I don’t know how to maintain it all I know is it’s called dwc and other people use it. There’s a lot of guys on this form that do use it and understand it quite well that would be better equipped to help you. Again unfortunately it’s just something that I never investigated or showed interest in.
Do you mean 420ppm* as 42 PPM doesn’t even sound right for well water unless you got some kind of filtration system.
I’ve never recommended anything but against well water. Most well water has a PPM of 400 if you’re feeding your plants at 700 more than half of your plant is eating well water solid and God only knows what they are.
Good you need to get that humidity down to 45 or 50%
I truly wish I could assist you further but unfortunately not knowing how to maintenance dwc or how it works I’m pretty much guaranteed to destroy your grow.
