Hello everyone, I have an issue my plants are about 3 weeks into flower and they were looking great. Over a 36 hour period the bottom half of my plants died.

Fox farms ocean blend soil
Fox farm nuts following feeding chart .75 strenghth
Additional calmag
Temp 68 to 85
Soil ph 6.8
Rh 39 to 47%20190717_193112.jpg 20190717_193130.jpg 20190717_193200.jpg 20190717_193112.jpg 20190717_193112.jpg 20190717_193130.jpg 20190717_193200.jpg

Damn! Sorry, that sucks. :peace:

Fertilized yesterday?

Anything the previous few days?

If you've been adjusting the ph of your water, have you checked your metre's calibration if using one?

Check for a bug infestation. Any signs of anything on the plants, check undersides of leaves. Possible even in the soil.

I’m leaning to possibly something in your soil. Get out a microscope (do you have a microscope for checking trichromes? Use that. Check your soil. Might be something there. Just trying to think what would move so fast across your plants.

Any sign of disease? Get all those dropped leaves cleaned up right away that would invite a whole ton of unwanted things

Sorry to hear, that really sucks. I'm thinking root rot or some type of fungal disease to damage a plant that fast. I see fabric pots and some perlite but is it possible your drainage has stopped and the roots are too wet?

I was wondering about root rot. It it’s onlt the bottom half of the plant. I was thinking root rot would just hit the whole thing or it’s working it’s way up. Hoping it’s something that can be corrected and not have to start over.

In the least hopefully the root cause can be determined to avoid the same issues later

I have a digital soil ph meter. Also double checked that by testing run off water. Root rot was my thought but its been going about every 3 days for watering. Plenty of air movement in the tents. No bugs on leaves i will check the soil. I have a digital microscope i hook into my ohone its actually super bad ass thanks amazon lol. Keep you guys posted

Well thats donski. Don't think it's worth saving however you do need to figure out what happened for future runs.

I agree for sure. Im gonna ride it out and see what happens. The guy i grow with seems to think it got to hot but 85 is on the high end but we have an AC in the room and its a basement room. Just really at a loss as to what did this. Was the tempature drop to much. I just really dont think it was heat.

And what ppm is .75 strength nutes you speak of?
have you ever flushed the pot out?
do you feed nutes every watering?

If you guys were feeding fairly heavy and regularly, then all of a sudden had a hot day or two, your grow partner could well be right.

I guess a couple questions from that. Would you consider that heavy feeding. I will be checking there ppm rating on the fox farms nutes and doing the calculations here in just a couple minutes.
And than, with respects to the feeding and a spike in temperatures. What is the direct correlation between the two?
Thank you

When it's hot, the plants drink more water. Less water in the soil, ec rises.

Same can be said if the soil was continuously wet.

Disease is by no means out of the question either, root rot, stem rot etc. Was it droopy despite seeming otherwise healthy before it happened?

No they were not. I didnt see any signs of over watering and he has been using a moisture meter in the soil. Maybe it was the heat. They still have not started flowering lost about 50% of the vegitation. They have been ok since i did flush them right after.

Maybe...

Check the stem of the plant near the soil line, just in case. See if there's any mushyness to the stem, if it's stem rot it'll be obvious. Just give it a gentle rub with your thumb.

Never used Fox Farms myself, not sure it's even sold here, never seen it. The chart should show ec values for each scheduled dose though.

If you flushed them and they've been ok since, your friend might be right imho.

I have never seen anything like it but it seems like a massive nute lockout to me. Either too much feed or PH way out of whack. PH meter?? roflmao.
