Wedding Cake mainline (Norcal Farms)

Transplanted without a hitch into final bags. The big 2 plants are in 7 gallon bags and the small 2 are in 5 gallon. Everything should just fit. I used coco coir from canna with the rest of my perlite as my additional soil. They took about 6 gallons of water between the four of them. I added a full nutrient solution, same as. I've been using for weeks. I watered and fed them a day after transplanting as they were looking really dry and droopy and I was a day later than expected due to delays getting new bags. By the end of the day they had perked up, but the following day I noticed a bunch of leaf damage on the big two plants. I cut the power back to 50% and raised the light by a few inches. I'm noticing a claw shape happening at the tips so maybe a nitrogen issue?
