Hey guys I'm in the end of week 3 veg and for the last week my plants have shown no growth..they look very droopy. Do u think its overfeeding ? Is my grow light too far? They are getting 450 ppfd right now ..my spiderfarmer4000 is 40 inches away from the canopy...temps 75f humidity 60-65 co2 1200 - 900
Thank you

They look pretty good. Maybe try increasing to 80-82F leaf surface temp and bump up to 600 PPFD. That should get you in line with DLI and VPD.
