Sudden leaf death

This is my 4th grow and amazingly


enough ive had excellent luck up till now. Everything was looking ok until just a few days ago and i really dont know what happened. Im guessing this round wont amount to much and want to make sure it doesn’t happen again. Any help would be greatly appreciated.

I dont have a tester for ppm

I saw your pH. I’m asking about runoff PPM rather than pH.

PPM is a measure of the nutrient concentration in your soil. I expect it is very high given the plants’ state. Runoff PPM should be maintained at ~1,000.

I figured that was probably my issue, was just odd how fast it came on . I also have been feeding same as first 3 grows but this is first time this happened.

Is there any hope for them? I flushed them good but worried its too late and they will be total loss.

You’ve got a challenge on your hands. I would get a PPM meter for future grows.

Are you discarding the run off and not letting the plants sit in this correct :love_you_gesture:

I see this in the pic now that you mention it. It will certainly cause big problems with pH, PPM, and potentially root rot. Root rot seems likely with pots sitting in runoff water.

Suggest using these:

My eyes see a ph issue. I have had plants go balls up fast in flower bad ph. Just what it looks like from here. Ride them out. You should finish with some nute/ph corrections. Can feed water only a week then get back on nutes. Should let them clean up the soil a bit. Recharge will assist also.

I would avoid products that encourage greater nutrient uptake at this point.

Given that the plants are sitting in water it is most likely root rot that is the problem. Cannabis hates constantly wet soil and dry cycles are very important for root health.
Raise those pots out of the water and let the soil dry out before watering again.
