for thinking it through BigD! Based on the pic I took of the open bag of Patio Mix, I would have to say it's less than 1% perlite, and I won't swear that my 50/50 calculation is so precise that I've moved my mix to 51/49 (or beyond) with what I've added. That said, when I pull out the clear cups on the cuttings, it's a lot of perlite, and probably too much. Might not be enough purchase for the roots to have something to grow in to keep it from being hempy.Well, I’ve been thinking about your “potting mix” since you posted your update photos yesterday. From the photo you posted, I kinda think the Sour G looks about the same as the other 2. Maybe they look different in person. To me, all 3 have what appears to be similar yellowing on the lower leaves. How much perlite do you think is in the Kellogg potting mix as it comes from the factory? From the pic you posted let’s say 10-20% by volume. Now add that to the 50% you added, that makes your “potting mix” 60-70% perlite. So my first question would be is that a good potting mix for growing in?
My second question would be that if you have a potting mix that has 60-70% perlite, should you be saying that you’re growing in soil? Shouldn’t a true soil have to be at least 51% soil of some sort? Since you have that much perlite, maybe you can‘t treat it like you’re growing in soil. Maybe you have to treat it like you’re growing in.......well.....something else. I just don’t know what that something else is.
Any way, those are just some thoughts I had. Please let me know what you think.
They all have yellow lower leaves, but the Sour G is much more evenly green above the lowest leaves where the other two on nutes are pale all over in addition to the fading lowers. The pots also seem to dry out very quickly on top but are very heavy at the bottoms.
All in all, probably not a good decision to go with that much perlite (as you suspected), and I'm glad this isn't the mix for the 7 gallon final pots!
I wonder if I should shake off the roots and move those two into new (maybe 2 gallon) pots with a more soil-heavy mix...like 70/30. Might slow them down a bit, but keeping them where they are isn't exactly spurring healthy growth.
