If you've flushed out the medium completely like you said, i'd feed them half strength base nutes for a week.. and then nothing for 2.
Now see....That "no feed" mentality till chop STILL blows my mind after all these yrs of the debate/debacle of "to flush or NOT to flush"......If you've flushed out the medium completely like you said, i'd feed them half strength base nutes for a week.. and then nothing for 2.
Well there yas go....Proof`s in da puddin....I usually start filling the res with ph'd water when it's time to flush and keep topping off with plain water until the res is just water, so I guess I'm a dwindler. I've been experimenting with low feeds and my best gpw yet was the blumat grow feed 1.0 start to finish. there were 4 strains that went in at different times, so the last one pulled was the only that got a proper flush and the first couple got none at all. the no fl ush plants were as smooth and flavorful as the fully flushed. I was upping the feed on these wifi bc it's a new strain to me and I'm still trying to dial her in... this is going to be a strain that will stay in my garden. I should have been watering to more run off...I was keeping it at a minimum since its a pain to drag them out of the tent or even lift them to empty the drip trays.
As long as you`re talkin bout "1/2 strength" flushes for couple weeks Bobbles , I`d say the end result could possibly end up around the same parameters as dwindling down feed till end of cycle......but....The residual salts were flushed out... But you don't know what stayed in the medium and what what into the plant. Synthetic nutrients are highly plant available and are readily absorbed, making it easy to overfeed. Overfeeding kills yields just like flushing too early when its not necessary. Not to be a dick dude, but your plants are over-fed. It has plenty of stored nutes, and it'll take at least a 2 week flush to get the green out of the fans.
Again, this is just my opinion... You have to know your plants and how they're going to react.
