I wish for you that your Schnazzleberry#4 is female and you also experience the wonderful pleasure of her buds!
I am looking forward to seeing more photos of your Schnazz!
To your questions...
I using in flowering time 2x 600W (Philips Master SON-T PIA).
My two variations from the Schnazz#4 need a "normal" fertilizer dose.
Give her some space! When she has space to the side, then their side branches can grow high with buds. More I can not say yet, this is my second run with her.
I use 7.5liter smart pots.
After the Aerocloner they come into small pots and stand under 2x 70 watts.
At a height of about 20-25cm I put the rooted cuttings into the 7,5Liter pots and there they grow up again 7-10 days under 400W. Then I switch to 12/12.
I mean I started the flowering at a plant height of 35-40cm.
Here would be a height of 30 cm the better choice ...
Currently I feed the plants once every two days. In the main flowering period then once a day.
I still have some hashish left of my last run, helps me to bridge the waiting time.
Here on our streets you get very rare good and clean weed, it is strongly compressed with poor quality. Smells hardly after Weed and has little resin. For health reasons an absolute no go ..
Own cultivated Weed remains in the small group of friends. For most hobby gardeners, their own harvest is too precious for the street.
