Need opinions on what to change, and how they are looking?

Hey guys, everything seems to be going well here. I've got my humidity levels at a good point usually between 45% and 75% sometimes it will it 80% at night. Temps are usually between 75 and 83, occasionally they will go higher or lower usually at night. Leaf temps are usually 3-5°F cooler, real slight breeze. Water is PHd to 6.5 from day 1,

The big plant is a purple marmalade i transplanted her about 5 weeks ago, the two topped plants are shockwaves, theyve been transplanted for about 17 days. the auto is tri cross from atlas.

Just wondering what the slight canoing is, also the topped plants seem to grow pretty thick and vigorously, but the edges folding up concern me. Other than that mild issue i think they look great, they're a darker green out of the tent obviously.

Canoeing is usually from too much light or heat. These otherwise look great.

Right thats what I was thinking, but my leaf temps are fine, and theres no other sign of light burn, they're under a 600w air cooled mh. And range from 14-18 inches away.

Its a 50/50 mixture of stonington platinum blend and ocean forest, extra perlite, tons of mycorrhizae and bacteria.
