Using promix bx soilless, feeding daily without runoff, never really check ppm, plant location is in the back of the room however getting the same light as the others. I run a dehumidifier when lights are off with a/c every hour for 10 minutes to adjust temp from 80 back down to 77. Humidity levels stay right around 55 to 60%. Running HPS lighting (4) at 750w.

4 lights at 750w total? Or each?

knowing this will determine whether you have enough penetration power for the size plants you’re growing.

250w HPS - 2ft plant height
400w HPS - 3ft plant height
600w HPS - 4ft plant height
1000w HPS - 5ft plant height.

You’re soiless mix is basically a hydro style growing method.

which means you should be knowing your feeding strength and you should ideally (not always needed) be feeding until runoff which depends on the feeding strength.

750w per light. Should I continue feeding daily just give them more until I get runoff? The soil is dry every day so feeding them a half gallon a day seems to be ok. They are in 15 gallon pots though.

Ok. I want some runoff then correct? I've gotten mixed answers on runoff. Some say yes, some say it's not necessary. Was told by one that a flush with just water to rinse out nutrient buildup would help as well. I'm all over the place! Lol

I water a 1g fabric with about 8c of nutes
2g with about 12c
3g about 1.5g

If you always water till 10-20% runnoff you won't need to ever flush the salts

I can't remember the last time I flushed, if ever, in Promix HP
