I am a first time grower having problems. I would love if you could help me assess what is wrong with my plants so I can fix it. Here’s some information about my setup.
Hydroponic DWC indoor grow with air stone and micro, bloom & grow nutrients switched out weekly.
Well ventilated with average temperature of 78°F. (1) 300w (168w actual) LED hydro galaxy grow light.
(3) OG Kush plants currently starting 4th week of flowering. PH checked regularly, and typically ran high at 7. I was using lemons to adjust PH, but PH would creep back up quickly after adjusting. I just switched water out tonight with nutes and adjusted PH to 5.8 using PH down (earth juice).
2 weeks ago I started seeing yellowing of the leaves, and it spread rapidly. I guessed it was a nitrogen deficiency due to the PH being too high. I pruned the yellow and dead leaves tonight and took a picture to help try and solve this.
I’ve included some photos of the plants when they were younger so you can see the progression. Any information on how I can fix this would be really appreciated… Thanks!
