Help with fixing nute burn

Hello all,

Background on my grow:
- In Week 4 flower
- Use Coco soil
- 1000 watt sodium bulbs
- Temp 75
- Humidity 45
- Nute burn
- Ppm is over 3000
- let me know if i’m missing anything
- 12/12 light cycle

I’m freaking out over nute burn, at first I thought it was russet mites.. but I checked with a 100 x scope on every plant and don’t see any sign of pests. All of the leaves on my plants look like the ones in the pictures. What’s the best way to flush to fix this?? They eat about 3 gallons per plant right now. I use the heavy 16 line. I feed every other day because they’re getting light ( I check by lifting the pot.) The schedule is nutes, nutes, then water silica honey calmag and terp. Please help. I have 12 plants and not sure what the best way to flush and fix this is... any advice is appreciated. Thank you!!!!

"If Run-off EC is High:
The best solution is to increase fertigation frequency. The most likely cause of high EC run-off is excessive losses to evaporation between fertigation events. Increasing frequency will help to prevent EC from drifting too high between fertigation events."


Nature of coco. Check your cal and mag levels....possibly increase.

Your really not able to "fix" nute burn so to speak, but backing down the amounts would likely be beneficial.

So I don’t need to flush??? Just back down on the nutes and they “fix” themselves?

Your ppm is at 3000+ holy shit! Do you usually grow with ppm so high? I've never exceeded 1450 in DWC. I've never used those nutes so I have no idea. Take it down to 1000ppm for a while or something.

First pic looks cal deficient and the last pic looks like some nute burn maybe or k deficiency .

Lower ppm to 1000 ...

Please tell us it's your runoff that's 3000.

What is the ppm and ph of your nutes going in?
