So I'm seeking help. I've had a recurring issue with my plants going herm. I've addressed everything that i can think of and it keeps happening. Need some expert opinions please.

I keep getting "true hermaphadites" that start showing week 2. Its only on certain strains in my room and never all of them.

Room is 12x10. (4) wall fans. Temp is 74-76. Humidity is 54-58. Lights are ThinkGrow LED 630W and they are about 18-24" from canopy.

I run straight coco in 5 gal pots with drain to waste. I water every 3 days right now. I've had issues with gnats in the past so I let my pots dry out (plants are not wilting at all when i feed).

I'm feeding Jacks 3-2-1 every feed with either Tribus or Recharge (Greengene's formula).

There are NO light leaks in my room. All the equipment is running properly. I have an iPonic that i monitor everything on and everything looks right on there.

Most recently, I got male sacs on my Papaya Cake, Ice Cream Cake, and a GG4xBwiz. I've had herm issues with other strains as well and it seems to only happen in the front half of my room. I originally thought some light was coming in under the entrance door so I covered that up with black plastic and the issue happened again this run.

I've replaced all my fans that gave off any kind of light, every piece of equipment that has light is covered by black tape. Its pitch black in the room with lights off.


What else could be causing these issues for me?

My only thoughts are maybe air flow( I dont have a floor fan) or maybe I'm underfeeding? Im at a loss right now so any thoughts on what could be causing this would be super helpful.

Thanks farmers.
