leaves on top canopy cupping and tips turning yellow/purple

This problem didn't start untill I transplanted into 7 gallon air pots. I used leaf litter soil conditioner/compost with peat moss and perlite and some garden lime. I feed GH FLORA TRIO every other watering. I did a flush of the pots even though the issue started about a week after transplant and I have turned down lights, lowered temps and raised humidity and none of this has worked. I can't figure out what is going on. I am thinking the soil PH must be off??? I don't know if I used too much or too little garden lime??? Need some guidance 20181111_114414.jpg 20181111_114414.jpg 20181111_114319.jpg 20181109_164324.jpg 20181109_164254.jpg 20181108_163426.jpg

The cupped leaf margins are a sign she's getting too hot / too much light. You may want to look that part of your grow over and see if adjusting the light distance helps. Your plants also look short on Mg. What is "leaf litter soil conditioner/compost with peat moss"? Is this something you made up? Do you recall how much lime you used per pot or overall? Can you go research it to see if you added the correct amount?

yes I made this myself. I eyed up using the lime. I am absolutely positive it's not to hot or too much light. I am going to get some regular soil and more perlite and re pot. After all the trouble shooting I have done, this is where I'm at. It has to be the leaf litter compost, it's a soil conditioner

tried buddy.kindbot.io which suggests iron bc of light green foliage, phosphorous bc of purpling, and heat stress because of leaf cupping
try it on some different photos to streamline your diagnosis
