ah nice one cheers.Not the kind he would want to smoke 😂
OP do the pots have holes in the bottom? The soil actually does look pretty soggy for healthy plant life. I would back off the nutes for a while, for causionary measure.
Transplant them into better soil/ bigger pots with holes. Change the environment then just keep an eye on em for a week, nothing more no nutes until vigor returns, theres plenty of time for that later. At least thats how Id approach
