ok i'm running a few DWC systems now and the last few crops i've had trouble with once i switch them to flowering nutes.

i'm running 400 or less ppm of a veg mixture of GH nutes (grow micro bloom (3x-2x-1x))

just wondering what process you guys use when moving to flower.

do you flush and put 400ppm bloom nutes in the day you move into flower?

or do you slowly change from veg to bloom? like first week in 3tsp grow, 2tsp micro and 1tsp bloom. then two weeks later go to 2tsp of each then to 1-2-3 ratio?

i guess just let me know your process.

thanks and +rep to helpful stoners.

I would stop feeding and flush two weeks before switching to 12/12, before starting with your flowering nutes.

My current grow I switched to 12/12 while they were still on grow nutes. 3 days of 12/12 with grow nutes then at my res change I went full dose bloom nutes. I think they handled the transition very well.

k thanks infex. they will only be in veg for 2 weeks so i can't flush them for two weeks. i'll jump straight into full bloom nutes then.

what ppm did you start them at on bloom do you know?

or at least what nutes did you use and was it full strength?

Not sure of my ppm during veg, I just got my ppm meter a week ago.
I used stealth hydro nutes for veg, gradually build them up to full strength. Like add 1/4 packet, if there looking good add another 1/4 a couple days later. Continue this pattern until your at a full dose. Then when I switched to bloom nutes I just went a full dose right away and things are going good. There are many different methods of switching from veg nutes to bloom nutes. As for me I try to keep it as simple as I can.
