Hey all! Due to some weird occurances, my first grow is ending up being 1 autoflower at 6 weeks and 2 autoflower seedlings at 4 days. I'm planning on leaving BOTH lights (Veg and Flower) on 18/6 hours/day. Is this going to be a problem? Suggestions?

Northern Lights autoflower
42%-58% RH
72-90 deg F
600 watt LED @ 24"
32x32 tent
3 gallon bags w/Fox Farm Ocean
Nope, won't be a problem at all. The plants will like the full spectrum throughout. One thing to worry about is your temperature; 90F is too hot. Most growers using LED aim for 85F max which will result in the leaf surface temperature to be about 82F.
Great! Sure seems like autoflowers are easier?! Yes, it's a bit warm in there and varies between 72 and 90; up high in the tent.. However when I crank up the exhaust a bit more, the RH starts dropping. I'll try increasing the exhaust CFM and setting the humidifier even higher. Thanks again!
@John Curry You may want to consider placing your temperature and humidity monitor within the plant canopy so you know the readings your plants are experiencing.
