ProGrow - I didn't know you are growing in coco too.:thumbsup:

You might try lowering your pH to the 5.7 range. That's more in the realm of hydro.

How big are your plants? What stage are they in? 400ml per day doesn't seem like enough liquid. I had some plants that I left too long in #1 pots and they were taking 400ml twice per day. They've been in #3 pots for one week now and they're using 1.25L liters per day. I know how much they're drinking because I measure my run-off. You do water until there's run-off, don't you?

PharmaCan Reviewed by PharmaCan on . ph of the grow medium alright been looking for a few hours and cant find a satisfying answer to my questions. so what do you all think: 1- sphagnum peat moss, perlite and vermiculite medium, is it soil or soilless. noone seems to agree but i would think it is soilless. 2- looked at all the ph charts (for nutrients availability) and some say that soil/soilless mediums should be at the same ph while other say soilless needs to be between 5.7-6.2 and soil 6.5-6.8 or so. damn it gets confusing. if any Rating: 5
