yo bro, first thing i noticed is yeah they look overwatered and damp.
I would get rid of the plastic bags around the pots, use a tray underneath them to catch the drain off water & don't let them sit in it, raise them out of it, ie grills across the tray(s) etc.. plenty of ideas how to keep your pots off the ground.
Reason being, this lets the water drain out and away from them, do not let them feed on it. most important!
it contains all the shite your plant doesn't want, salt buildups etc.. so ive never let my plants drink what they 'eject'
...If your getting too much run off water when feeding tho and that is the main reason for the bags,,,, then water them slower bro, from the middle. start with little puddle first and give her time to soak. if you put too much on her, the water will just 'bore' its way out of your pot, waste of feed.
I learnt that from here many years ago and by jiminy it works! essential info.
Some actually water with plain ph'd water first so the soil moistens before feeding starts aswell. so plenty of methods out there, just don't let them bottom drink their own shite. lol
ventilation and good air flow is a must, especially at pot level. Airpots are probably the best for that as they covered in holes.
So, change your setup dude, get good air flow underneath them and around them so they can dry out properly.
If you water plants too much they become lazy anyway, don't grow as much, I water mine on the brink of drying out. just as the lower level of leaves start to sag or its Dry/moist on the moisture probe
And yeah I also agree that get a separate better ph meter, if that is your correct soil ph reading then it is too high.
But,. the soil will 'buffer' it before it gets to your plant so for a more accurate reading of PH, test the run off/drainage water, that will tell you more.
Foil on the top is ok, but again, it can trap moisture.
Lightmix soil for everything bro aswell is the best bet to start with, nice and 'light' on the feed for germination to seedling, then you can feed aswell without worrying about too much. BioBizz Light Mix is the best on the market imo
second atami janyco lightmix. Ive tried all the others and they just seem to be too rich.
Good for the experts out there tho, but for a 'bung it in and grow' dude like me? Lightmix all the way.
well, without writing an even more biblical post, ill end it here for now.
Best of luck to you and your plants bro, if your going to start again with a new setup,then my final advice would be.. preparation is the key and prevention is better than the cure.
Plan it all out, ventilation, drainage & watering, and youll be sorted.
it is a weed after all and will grow in many harsh conditions but with the perfect conditions, you'll outgrow your tent lol.
Peace.
