When (if needed) to stop feeding and flush on organic grow?

If you have only used water up til now or the odd compost tea, just run plain old water from now til harvest. Not many super soils can hold enough nutes to last past the end of flower without being so hot they burn the plant in veg. So unless you have used nothing but compost teas, plain water from now til harvest will be just fine. Id also go a few days longer before harvest as most soil plants can happily take a few WEEKS longer in the soil without any probs, so a few more days will help ripen it and pack on more weight. Every day counts at the end so when you think its ready, wait 2-4 more days THEN harvest, just trust me on this ok. I swear it will help. If it doesnt, DM me and Ill send ya some free stuff. 😀 Thats how sure I am it will help.
