Big Bud autos day 38. My question is when should I stop using the nutrients and switch to just water? Thanks I appreciate your help
most of us would start a flush about 2 weeks before projected harvest date. Watch your trichomes closely and then decide on your preference . For a more heady uplifting experience harvest when most of the trichomes are cloudy . for a couchlock effect harvest when a good percentage of trichomes are amber.White widow auto usually takes about 8 to 9 weeks to mature once it starts to flower
You have quite a while to go before you need to worry about that.
I just harvested a white widow x big bud auto. It wasn’t ready until 77 days from germination (80 from seed). Those plants should have A LOT more growing left to do.
