i have never seen this kind of curling.
sog beds happy frog soil fox farm sched.
hortilux bulbs
thrips in the beggening but taken care of. (i think)
black white poly for bed liner in one and black plastic tarp for the other( i suspect off gassing)

i have this strain in two rooms and two dif mediums

do the beds have drainage? have you run those beds before with this nute schedule? did you start feeding the happy frog right away?

Im confident saying you got some Magnesium deficiency forsure... most likely caused by ph probs.

im not sure if the curl in the leafs is related to magnesium (it might be tho).. looks like heat stress??

What I'm thinking too, amended soil in a bed without drainage getting fed could buildup salts and throw pH off.

Some people like to say FF nutes are lacking cal-mag, but most major nutes have complete micro packs

Leaf rolling is generally considered to be the plant defending itself against extreme environmental conditions.
How hot and dry is it around the leaf surfaces?

i have ran these strains before but never the beds i was very concerned about drainage from the get go. the first bed showed signs of overwatering the first few weeks the second has not.
the temps are on point and the humidity has been good. we have had thrips. no ph water tester here.
the strain in question is very sensitive. i have 9 plants of a dif strain in one of the beds and it is unaffected.

ps thank u for the feed back it is unquestionably appreciated

The cuts were from an outdoor ma and that is prolly where the thrips came from
