when do i stop giving nuted water?

i want to give my plants just water for the last ~10 days before harvest, but how am i supposed to know when that is? am i just supposed to stop nuting and hope that in about 10 days the plant has reached its peak? i got some blue dream starting week 6 tomorrow. i wasnt sure if i should let them flower for an extra week cause they seemed a bit behind.

edit: im doing DWC Hydro with house and garden

Well, don't just stop. Start giving them half of whatever you are giving now, about a couple weeks before you expect to harvest. Water the last week, or whatever. Really depends on how you are growing. In soil/organics you can pretty much just give molasses\humic\fulvic acid in small amounts the least couple weeks, you probably have enough nutrition in the soil until harvest.

Oh yah, and some people who grow with synthetic nutrients advocate flushing with lots of water the week or so before harvest.

I don't stop feeding my plants.

I never stop feeding mine either, just not as much.

im doing DWC hydro. using house and garden if it makes any difference

flush 2-3 days before chopping if you've been using the drip clean. I change my tank twice within the 3 days with straight RO, never have any chem taste what so ever
