Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?

Delaying Senesence?
Delay Senescence in cannabis while employing a staggered harvest? Is this possible? I'm thinking about cherry picking my top colas as they are milky and starting to turn to amber. There are also new bud sites that I wish to feed and maximize yield.

Flush?
I have never tied to flush a plant and I seen if the leaves have too much yellow then it is not a good idea. I plan on doing a harvest in 10-14 days and wanted to know if both of my plants should be ok with a flush.
