I'm on day 15 of veg. And my leaves are getting spots and curling up. Can anybody help me out with this. My PH runoff is 5.9. I'm growing in coco with a dripper system. I'm running lux lighting 680watts and I have them at 45%. My humidity set point is 65% during the day and 55% at night. CO2 levels are about 600ppm, vpds average between .8 - 1.0. Any help will be appreciated.
Need help.

have you fed them any nutrients yet?

That's some plant stress. The purple stems plus taco'ing suggests that there's some stuff that's making your plant unhappy. Heat stress? Wind stress? Light stress? Also, I'd explore ideas like a magnesium deficiency.
Yes. I fed them a few days after transplanting
Ok. Thank k you
I flushed them yesterday. My runoff was at 5.9ph level. My ppm's were at 1450.

Your doing this every day? 1450 is that the in going or out?
No. I'm feeding and flushing, rotation every other day. The 1450 ppm was going out after flushing yesterday.

COCO you want to keep your EC & pH stable water feed water feed doesn't work good as your plants are on a with and without roller coaster. Find the right nutrient strength where you can feed every time you water until slight runoff then no more watering until it dries back a bit but never dries out.
Kinda looks like a mixture of messed up EC/pH and heat/wind stress.
Do you have fans directly blowing on the plants and another question are you spraying the plants while the lights are on?
Kinda looks like you might've roasted the leaves by spraying them while the intense lights were on and it fried them.
