No worries bruv.
Yes, this is the ONLY feed they get @ ph 5.8. Jar is sealed tight when not in use.
I switch to this feed after the drought, at the first signs of trichome maturation. In my most recent trichome check we are starting to see some amber/cloudy trichomes. The buds look plenty swollen and the pistils are mostly orange/red.
These signs let me know that the plants have 1-3 weeks left before I harvest them, so I switch to the finishing feed. Then continue with just banana tea until harvest, whether that be 1 week or 3.
If doing this in coco you could add a little sulfured molasses and a touch of silica (in the form of mono sicilic acid, not potassium silica) to the mix as well. These will give you an extra boost of vitamins/sulfur/silica (building blocks of Terpenes and Trichomes), and a sugar boost for any bennies/mychos your running.
My opinion is that at this late stage I'm willing to take a potential 1-3% hit in total harvest weight (by denying the plant nitrogen and other nutrients) for a boost in smell/flavour. At the end of flower I've found this regimen to be the second most impactful on getting a top shelf end product after temperature/humidity.
