I’ve been irritating at 5.8 to 6.2 and have been having issues. If the ph is fine I may need to dial in my feeding better

Promix hp contains lime in it. At what range would you recommend for this growing medium?

Ph is 6.5 to 6.7 after nutes. Also what would you recommend I do to the fresh water between feedings?

Every representative of promix I’ve spoken to has said that ph ing irrigation water does not effect the ph of the promix itself. So very confused of what ph range I should be irrigating at, considering its a soilless medium

When I ph down the irrigation water the alkalinity goes to zero

My well water is 8.2 ph 125 ppm and 60 ppm alkalinity. I have been having issues, I ph down the water to around 6 for feeding.do you think I would be better off not using ph down?

Do you think im safe with no extra cal mag if im not using ro water. As the gh flora 3 part has cal and mag in it?

ok thanks, thats what ive been doin and they seem to be liking it. Just transplanted to 3 galon fabric pots. Do you use the same ph roughly when your using plain water. And do you go fir runoff every time?

Also i use well water that comes out around 120 ppm no softener

Ok thank you. Since im not adding extra lime should i go with a lower ph and promix hp comes with added lime.. im also using gh flora 3 part with no other suppliments. Ive ran promix hp before and did the 6.0-6.5 and had some issues

Thank you for the reply, my plants are already in pots. So im looking to use the promix as is.

I have read that it should be treated as soilless and should be around 5.8 but also have heard higher.

Anyone growing in promix hp would be a huge help if i could get some insight on what the ph of my water and feeds should be. Also should i feed nutrients on every water since your supposed to tet run off with ptomix HP?
