Running into issue with my plants (pics included)

My plants seem to be doing fine but I've started to get some curling up and light green on the edges of my leafs. Any idea what it could be. I'm growing in fox farm soil and watered right before the pictures were taken. I will be out of town until Sunday and am super stressed out about them. How serious is it and will they be ok when I get home Sunday night?

Looks like it might be k to me, or a mg problem but if you could get a closeup of the leaves actually showing the issue it would be much easier to solve for sure.

not sure but doesn't look serious, could be calcium or copper deficiency, make sure the pH level is between 6 & 7. Possibly heat stress so careful with that. Also never overwater your plants, only when the top inch is dry. Good luck
 
Ok. I overwatered to give them a little extra to drink while I'm out of town. My temperatures have been 75-77 consistently although there were heat issues earlier on in the grow. I always make sure there water is on point with ph recommendations. Does anyone have any recommendations on what to feed them when I get home Sunday night? I appreciate all of the help. This forum has been a life saver and I'm happy to be a member of it.

So many problems here I'm shaking my walking stick...! remove that drip tray, paint the pots black(?) look to your roots as curling leaf margins indicate this... sniff you roots for stink... is the best advice here.. google Pythium, I hope I'm wrong...? ensure that that bucket has at least 24 x 1 inch holes minimum then flush!!

I really hope you're wrong about Pythium. What's the reason for black over white? Thanks for the help.

Compacted deep roots like in the pot you have are ideal conditions for root rot(Pythium) you just need one spore and its good night to all, deep pots like this are a great way to SQUEEZE out the air in the root zone(compaction) no air and much water makes rot, .. add a spore and again its very bad, if the light gets in thru PET translucent plastic, then you can also expect Algae, a long shot perhaps, but still a chance, I know as I struggled for a long time with this cause my trainer years ago always said cannabis likes a deep pot, I still agree but it has cost me several grows and a lot of un necessary money trying many pots, but air pots are the best and not very deep either.

see it as layers of saturation, the bottom layer too wet the top layer bone dry ...?

What's the reason for black over white? ...........the real reason is the plant hormone Epi.....(fuck can't remember the name in English) only works in the dark, and is the babe that makes root, as per 18/6 vs 24/0 , compare root development, and also used by cloners, esp. bubble cloners thats me, keep the cutting tip in the dark fed on ph neutral water annd air, and the "Epi".... grows the rootlet in about 10 days.............................no I need to find that "e" word ..lol
