I am using a potting mix from a local garden center which is called "special substrate" w/ a bigass picture of a Cannabis plant on the bag. The mixture is very airy & spongy and otherwise feels and looks great, pretty much such as Cannaterra Pro or similar more expensive special mixes.
It's a mix of coconut fibers, peat moss, organic compost, perlite, prefertilized w/ minerals and micro elements. Based on the description it should be IDEAL, I can get this for €6/50L bag right across the corer.
What concerns me is the ph which on the bag says 7.3ph which to me seems one point higher than what it's supposed to be.
My plants always run into one or the other problem at some point, yellowing etc..etc.
Please take a look at the description of this potting mix and tell me what you think.
I am growing organic (Plantmagic Oldtimer Veg/Grow nutes) and my tap water is very hard, 8.5ph+. Although when I add my nutes, my water goes down to 6.3 or so.
Now I am debating whether the high ph of the mix has something to do with my problems, whether I could lower the ph of the mix one point by adding more peat moss? (Say, I'll add 20% of peat moss to my bags of soil to get it to a proper ph?)
Any thoughts? Thanks!
Edit: Another thought of mine is whether I should stop using prefertilized mixes and use light mixes instead...whether this has to do with my problems. (However I usually don't start with my organic nutes several weeks into a grow)
