To much light?

Day 24-25... So these were light green overall a few weeks ago, with shaded leaves darker green. Things started looking really funky by day 10. I think I wasn't keeping up with the feed, trying not to over do it like my last run. Difference is, I've doubled my watts, I'm running about 520 watts of HLG QBs. PAR at the canopy has been around 800. I'm seeing a red/purple. Is this molybdenum deficiency? I know this is used to transform nitrate nitrogen in to a usable form, maybe there's not enough to keep up with the lights?

My setup: ffhf with perlite, veg bloom dirty, soil runoff/pH is around 1000ppm/6.3-6.5ph, humidity is 60%, canopy leaf temp is anywhere from 78-81f, I'm in 2 gallon smart pots watering to runoff every other day.

What's the distance light from canopy?

About 22", I don't think the distance matters regarding temperature, but I'm wondering if my PAR is to high. Leaf temps are 78-81F.

What size tent?

4x4

With that light at that distance in that space I don't think its too much light.
Don't see an issue with your rh /temps.
Look like elements of P def and low on nutrients as a whole.
But that could be an overall nutrient lockout, some burnt tips would suggest your feeding wasn't too low. If it were just lack of nutrients you would likely see more leaf death on the lowers first.
1000ppm seems high.

Sorry I cant put a definitive pinpoint answer on it.

No problem thank you

looks like a Ca problem, can't be sure, maybe start of, ya can a little browning in the sugar leaves, and also with a tip curl too...

Not really brown, it's purple, and it's happening throughout all the light exposed fan leaves as if it's a mobile deficiency

really hard to say then....i know when i switch the led's and cob setups i've come across Ca problems in the leaves itself......it's will start as a purple in the beginning and turn to a brown and move the rest of the leave yellow as it were as a CA does.....sometime u can smell it too just saying......maybe some better eyes can look and see.....

keep an eye on it is all i can say right now mate........
