Is this underfed or overfed?

Damn. Just opened the tent to check how things were going and found a bit of water in the tent. It looks like one of the float valves got stuck. I think it is all fixed for the moment because i switched it out with a clean one. I guess i better get to cleaning the others right away so it doesn’t happen again. Too bad it’s so late. Can’t do it tonight.

Thabks for the suggestion. I might try to take one out and see but kinda just want to let them go for the last bit with the least amount of work as they are 20 days from being finished. I am planning on emptying the reservoir and filling it with plain water or maybe water with barely any nutes.

Its not work mate. It's basic diagnoses.
It will take less than 10 minutes to lift the pot (they are designed to be removable) run a few litres of water through and check the run off.

Running plain water through your res with a bottom feed system won't fix the issue if the issue is salt build up because you won't flush the salts out like that.

You might not make them better but you will learn valuable information and they could get a lot worse if you don't

. Also starting the plants in the autopot final container since they are autoflowers. Also i will probably have 1 autopot with the last of the Pro mix HP and using coco/perlite in the others. Can’t think of anything else at the moment. If anyone has any other suggestions let me know.

Don't try and have one auto pot with promix and others with coco.
How would that work?
1 res feeding multiple plants, one with totally different feed needs than the others...

Thought i would post a picture of the reservoir as i finally had the energy to take it out. I sucked some of the water out with a shop vac before the picture it was a lot worse with more stuff floating. Also some froth at the top. I am thinking i might see about placing it beside the tent instead of the back. I am not going to take PPM and PH of the water in the reservoir as it is extremely dirty and don’t want anything sticking to my meters. Should have just taken the reservoir out earlier. ‍View attachment 5292007

Dirty from what? I see a lot of salt buildup, but it also looks like you got biofilm growing as well.

i've been running autopots for years, soil/perlite mix, always keep my ph 6.5 to 7. I had problems when I was using hard water from the tap, your res kinda reminds me of what I used to see at the end of a grow
Also the limescale caused my lines to clog up and occasional valve blockages

I think it was because i was putting in warmer water at first. I was using water at approximately 23 C. I also left the lid off the reservoir for a couple of days by accident so i am not sure if that has anything to do with it.

Let me know if i am wrong but I thought that coco and promix are very similar. I thought it was the same PH also they both are inert soilless mediums. They can both take remo nutrients.

6.5 to 7 PH? I keep reading 5.8-6.2.

I've been there before. I use 1.5ml per gallon of bleach in my res. Keeps the biofilm at bay.

The lid off shouldn't make much difference, unless the area the res is in is lit up. You should try to keep the res in the dark.

Coco is coco coir, promix is peat moss. They're completely different. Peat is more acidic, but I believe promix might add lime to offset the acidity.

It was. It was in my tent with the CMH running constantly.
