Looks like a little nute burn but it will be fine. May want to cut down to about 1/4 strength, they are still kinda young... Your RH is too low too man, cannabis enjoys vegging in the 70%-80% RH.... 35% is dry as a sandpaper handjob...

81 degrees isn't so bad.. I like to stay around 75-80....

thank you. this is my first serious grow and just wanted to confirm my suspicions. I have a air purifier with ionizer running all day could this be droppin the RH or just he heat? when the lights aren't on it zooms up to 70%.

Your light(s) are most likely dropping your rh.. if you have room you can set out some containers of water to raise it a little. I put a 5g bucket half full of water in front of a fan and it raises my room about 5%-10% depending on ambient atmospheric conditions in my area.
