Yes m8 lol, organic soil has loads of buffers, by the time the water has sat 48 hours in the bucket, with a bubbler in it, the ph has risen from 7.2 to around 9+.
Plenty of gypsum in the soil, provides Sulphur and more but is an acidic buffer, brings down the ph.
BIG pots help buffer the soil better as well. If I see what looks like a deficiency, then I just do a low pH watering, to switch it up a bit, there is plenty of crab meal in there to bring the ph up a bit. Also helps the bacteria that like a lower ph, keeps them in balance more.
The problem is in the 5 gal pots I have to be more careful, they don’t deal with PH buffering as well as the 10gal pots. If I could get 9 x10 gal pots in my veg tent, I wouldn’t bother with the 5 gal ones at all.
Good excuse to get a bigger veg tent lol.
