Heat stress bro... I think that light is to close. 600w HPS? How close is it?

Also need to get that humidity up over 50% min. 60-65% at this stage would be good

They would be fine at 4' for this stage. I'm an led guy but hps throws some decent IR.

Those signs scream heat/light stress and low humidity.

Maybe someone with experience with 600w HPS can chime in here?

@MIMedGrower loves when I tag em for this stuff lmao.

I never get to say this but is that soil too dry?

And i need at least 4 feet in a 4x4 tent from the canopy with a 600 hps. I was at 40” with happy plants with a 315 cmh in a 3x3.

So maybe a bit close still.

IMO HPS is not a good light for seedlings. Too close you get stress, to far away you get major stretch. CFL or MH work better. I introduce 50% hps 2 weeks after flip. Also as another poster said, keep the humidity over 40-50. GL happy growin.

Many say autos are different to grow but i didnt think so much. They can vary with strain like anything else.

Agree maybe a little bit lighter feeders from what I see around here.

Wow. You folks are good. A consensus of solid growing advice with no bro science. The flu may have positive offshoots.
