Hi All-

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!

Air. Without even seeing your airstones I can tell you don't have enough.

Keep air hose length as short as possible. The longer the hose, less amount of DO you will ultimately have from the same pump.

You literally cannot have too many stones or air pumps. Turbulent water only circulates the water more.

Use h2o2 it will help clear that rotted root. Change water while that shits coming off. Plus h2o2 gives off more oxygen

Thanks everyone! I've got a plan to fix this now.

1. Add hydroguard to reservoir to stop more root rot.
2. Add additional air stone(s), with stronger pump.
3. Learn about PPM's and make sure I'm not over feeding the plants.

I've got 40 days left until harvest so I'll make sure and post a picture if these girls ever recover.

it looks like a simple nitrogen lock out from the high ph. a good aid to root rot is tarantula and piranha from AN.
