Hey everyone I’m new to the site but not new to growing, However it is my first time growing with dwc. My plants have been doing fairly well up until last weeks of flowering. The leaves feel dry and possible deficiencies.

Hoping some of you can give me some insights and advice on to what might be the problem it would be appreciated
Ph-5.8-6.2
Res temps 68-75
Room temp day- 78-83 with 800ppm co2image.jpg

It's hard to say with your yellow lights going and the limited info, but I'd say it's a P shortage, which isn't unusual in flower. If you're a week away from harvest, I wouldn't touch them....even, if you're 3 weeks away from harvest I wouldn't touch them. Good luck

Hey bunny, Yes there have been times when the res was a little under half but I was thinking that it was better for the roots to get more oxygen and fresh air every now and then , also very minimal to no nutes ,

Just from issues this run I found if I missed a a top up I would see potassium deficiency issues pretty quickly finding at one stage I needed to top up over 10ltrs from just missing one day/night cycle in a single 55liter 10 makes a massive gap and concentrated res water.

Also my Ppms in the res are running about 430, Was wondering if I should be increasing to about 800 or so until harvest
