Personally I wait till 14 days to harvest, Then give the plants straight water untill the end. I also Have waited untill 1 week to harvest and then used a flushing solution 2 times then 1 straight water like 1 day before harvest. I found my best results to be the 2 week straight water solution. Either way I suggest removing the plants that are not ready, If they are in fact going to get the straight water or flushing solution, because they are in the same tray........Ok I just re read your post. I see you have waited untill the final week to flush, I wouldent have done that, but now you should use the clearing (flushing) solution method I have explained. Get some general hydroponics floral kleen, or whatever your local shop carries, then follow the directions on the bottle. And no, it wont harm your other plants, but will stop them from getting there final vital nutrients they need in the last 3 weeks, so i suggest removing them if your able to do so.......Later
I'm using a 4 x 4 hydro tray with 30 gal. reservoir. 3 plants will be ready to harvest in a week to 10 days. The rest need at least 3 weeks ( different strains).I use all FoxFarm nutrients.I was wondering if I should start feeding just water to flush, or will it harm the plants that still have 3 weeks to go. I was thinking of taking the 3 and puting them in a DWC for the flushing, so I could keep feeding the late bloomer the nutrients. Someone said with the reservoir set-up, I only need to flush for 2 days to just keep the plants together would be fine. wow I just read this back and it sounds like a bad math joke...sorry. I made some mistakes on my 1st grow and just looking for some ggod info....thanks
