Having an ongoing problem. Possible deficiency?

[Clydecross]

Both of these are in veg. One is in a soil blend and one is in coco. They use a 700 ppm advanced nutrients 3 part nute that regulates the PH. They were doing fine in the new tent and all of a sudden they started having this possible deficiency. They haven't changed the water being used. It's been the same since started. It gets up to 80 degrees in the tent sometimes but not all the time. Can go over all the things tried but it's a lot. Can anybody extrapolate what may be going wrong from this information? Appreciate any help immensely.

Can you go over your watering practices and specify which plant is in which media?

To me looks like these clones have struggled from the start

Looks like drowned roots. Or an overdose of food.

Yeah lockout for some reason or another

Sure! Everything is very novice, with a couple successful grows for experience. It's entirely a hobby.
The pic with the gallon jug to the right is the coco. The one without it is the soil. I water when it gets a little dry. I mostly go by how heavy the pot is. I was feeding about once a week with a 700-800 ppm. It's a 4-3-8 NPK. Also the coco pic was transplanted from a hydroponics system. It was using deep water culture. I don't think I was doing it right so I put it in coco to try and save it. It was successful but maybe unnecessary. I think whatever is causing them to do this was the culprit all along. Here's another of the soil.

How do you tell its dry and how much water how often?

Is the top of the soil looking kind of algae covered and packed down? I feel like your media either isn't draining well enough. Or you might have watered too soon.

I just feel the soil. Pick up the pot and if it's light I'll water it. Maybe I'm misconstruing what constitutes as light?

I don't see any algae and it doesn't seem packed down. I usually stir it around before watering. Could I not be checking deep enough?

Should feel almost like styrofoam. In soil your over feeding and watering is my guess.

The coco is what brand, type of pot and size of pot? They are very different media.

Read this on watering. You cant go by the too of the soil at all.

Can you test the ph of your runoff for both?

Marijuana Watering, how media, pot size/shape and environment affect it

Ok lots of posts on how to water plants. So I thought I would put together a thread on how different factors contribute to different results that ppl see. This will be a long read based on my personal knowledge, opinions, research and others work to consolidate information for our members. I'm...

What is the ph of the water you are using straight and with ferts?

I believe I am over watering. The coco is grow organiks. The pot is 7 gallon fabric bag. The PH was running high but not extremely. Last was 6.8 for the soil and 6.5 for the coco.

What is the ph of the water you are using straight and with ferts?

The ferts always come out approximately 6.5. it's a 3 part system for ph control. The water is usually right around neutral most the time. About 7 or so.

So your measured ph is 6.5 when you water with or without ferts in the water?

I stab my finger right in there. And I rough up the surface soil from time to time. I like a nice loose pack on my media. Lots of perlite. Very lightly packed. If they take too long to dry out its a whole ass problem of its own.

Yeah pots to big and not drying fast enough or dry enough before the next watering. Plus nutrients i am assuming are building up.

With ferts it 6.5. without it's about 7.

Cool. Thanks for the help. I appreciate the interest.

Hmmmm. I guess if you had some perlite and some dried out promix you could pull it out of the bag. Break up the dirt ball. Add some perlite and dried out media and try repot it. It's a tough fix. It will add 3 weeks or more to recovering it. Is it a superior strain?

Do not PH adjust those nutrients
