GH floral trio work great in coco.
Start with a turkey baster as a watering tool.
Feed the outside edges of the cup to get the roots to chase nutrients.
Try and get just a little coming out the bottom to get the tap root chasing it.
Keep your coco moist at all times.
But always with nutrients.
Low ppm’s at first 400 ish at 5.8 ph.
Be religious about the ph it’s important.
Gradually up the ppm to match the GH schedule week by week and you will be ok.
I have several threads on coco and what to do for best growth and health.
Heavens Shore’s has the most pictorials.
How are the girls this morning?
Stay safe
