Promix HP-CC

[Hookah79]

Made the switch from regular promix hp to promix hp-cc and it looks like i got some kind of a lockup.The thing with the hp-cc is that it retains moisture,so less watering obviously. I would water/feed/water every 3days or so with the regular hp.But with this new hp-cc i went 4 or 5 days between each watering/feed.I had hard time drying up this medium.i checked the drop off and the plants were at 2000ppm on the average and this at veg state.They're in 10 gallon pots ,so i am thinking that right there could be a problem since the medium has coco and you don't need a big pot for it.

I flushed the plants ,any suggestions on how to work with this medium?

What's your feed EC? Has plant growth stalled?

Small pot coir relates to pure or coir dominant mixtures. HPCC is peat heavy with 20%ish chunk coir, no?

EC was around5.5 after first flush.Just checked a 2 day old drop off from one plant,it is at 1.0 EC and 700 ppm,and that is after feeding them(2 days ago).Yes some plants have stalled growing.

Feed EC re: what you're watering with.
