I don’t use HPS but I think you need to rise up a little more your light… Maybe @WillyJ can share his opinion on this (I think him is using this type of light)

Yeah 14 inches away from hps is way to close for a 400w or more.

I have no more room to raise it. I just tied them away from the light to see if it helps

Do what you have to, to make harvest and learn from your mistakes. That’s all we can do as new growers. Slow lst training will go a long way in a week or two. I’m sure you will be ok.

The manufacturer of my hoods recommend 12"-36" for a medium watt system as long as heat isn’t a issue… high watt 18"-48" low watt 12"-24" @M4ur


Watering issues what’s your RH and temps with a 400w HPS 10-14" is almost optimum if heat is kept in check. If you are watering often humidity rises actually making it harder for plant to drink your plant evaporates water through it’s leaves as it breathes this creates pressure which draws water and nutrients up from roots :wink:


Thanks @Donaldj I just adjusted my hps, I really thought it need to be higher.

@M4ur and @Frescal

I use H.P.S 400 watts for veg and 1000 Watts for flower. I keep my lights about 3 feet from my plants I give them all the room to grow plus i don’t have to move my lights all the time either lol

I just moved my tall plants to my led light side. We’ll see if that fixes the problem. I have a 750 hps on one side of the tent and a 700 led on the other side. Both my tall plants affected were on the hps side

the droopy leaves could also be over or under watering or root bound @Frescal


Thx bob31 im going to try watering a day sooner. Usually i just feel the top inch and if moist i wait till dry
