Hi pasimito!
You SAD autos are looking great, congratulations. Now they only need to get mature and get the flowers more compact a yet a bit fatter. Will be a good production, I think.
Regarding the nutes I personally like that the plants loose all the nutes in the final weeks. If these plants were mine I would just give them water from now until harvest, which would probably allow me to avoid the flush. But if you want to give them some more nutrients do it only once or twice and don't abuse on the dosage, maybe half the dosage mentioned in the bottle would be enough.
Keep it up mate. All the best and sweet smokes! :Sharing One:
