ken = The last time I measured runoff I had an EC of 4.3 and a pH of 4.7!
That could be due to soil. ken, flush with a 6.5ph untill Ec drops to 1.0-0.9 Ec
The ph should rise as the nute is flushed down. Dont worry about overwatering, as they wont be sitting in water ok. The plant will take up a bit of the 6.5 flush, the rest will just go through not affecting the plant at all ok. make sure the flush water is warmed (Kettle Pre-Ph'ing) to 23c.
As the Ec of 4.3 drops by half or more, up the Ph of flush with "Silica / Silicone" to Ph 8, not humic acid, it will add to low Ph issue ok,. Then continue flush out the rest of nute, as you do this the ph will rise back to 6.5-6.8............... and you are back in the range required for P & K uptake Ken. I know it's a lot of work, and a lot of H2O@23c & Ph'ing. And Ec'ing, but worth it, results will show in 6-8 days post flushing.
if you have an airstone & air pump, put in flush water from the "Tap" ?? over night to degass the water and re gas it with Co2 & O2. Them warm it 23c then Ph it zero nute.
One good thing in this situation is tap water is high in alkaline salts, which will help bring back up your Ph ken. tap water after 24hrs on airstone will probably come out at Ph 8 anyhow............ if you dont get ph back up the flower cant take up the whole amount of P & K etc........ decreasing yield a tad.........glad you got the intersex items out as early as possible.......
Overwatering is something that occurs on a "Chronic" basis not acute, as with acute flushing ok, dont worry they wont even feel it @23c, as long as the first round of flush is 6.5, then move up to flush with Ph8, untill run off Ph comes down to 6.5-6.8, not above 7 though ken ok Automaster
Uptake depletion ranges outside 5.6-7Ph

the combined Ec meter looks a nice bit of kit....
