Curling

Hi, I'm a first time grower, hand watering in coco and using Canna Coco A&B and Rhizotonic at 1/2 the recommended levels, watered once a day enough that there is run-off from the solo cups. That said, I started my seedlings into solo cups with drain holes, those cups are set into my 5gal smart pots.
I was following the general grow advice on https://www.cocoforcannabis.com

This morning I noticed the tips on the serrated leaves began curling upward, a few hours later and now the leaves are warping as well.
What could be causing this, and how should I correct it?

Don't try to correct it...let the plants grow a little. Be sure you're managing your pH. If it were me, I'd take them out of the larger pots and handle the solo like any other pot; individually. Be careful not to over water them at this stage...I've seen plants 5 times their size, in solos and they could go 2 days easy between feed, so perhaps daily feeds aren't quite needed at the moment. Just my two cents. Good luck friend.

Thanks

Could be a tiny bit of transpiration stress from heat/light/RH and-or fans What kind of lights, how close?
Also I believe coco has to be pre-charged with calmag. if the distorting leaves begin on new growth, make sure it's not a calcium lockout.

Like CannaCountry said, give them time to work themselfs out before trying to correct a phantom deficiency.
