Water it slowly, painstakingly slow….as in go around the outer 1-2” and let it soak in for 5-10 min.
Then hit it again but extend the water closer to the center.
Do this, outside working in, w/ as much time between as u can stand.
Do this until the entire medium is soaked, but u DO NOT want runoff. I’ll always water until I get a few drops but no more. This lets me know that it’s completely soaked.
My plants in 5gal pots usually handle 1-1.25 gallons of water before it starts running off.
Then them dry out but not bone dry. You’re running an organic grow, so U want a certain level of moisture.
If you’re not PH’ing, U may wanna start.
I’ve used Gaia Green forever…..and had great grows in soil, straight coco, KokoBop and about everything in between. In their soil I’d vary my PH input but keep it in the 6.3-6.8 range.
There’s no way those plants don’t get with it, if you do what I’ve said.
If your VPD & lighting is halfway decent, they’ll get dialed in and bounce.
