So, this is actually copied over from here https://www.icmag.com/ic/showthread.php?t=192322&page=4 .... anyone who's curious about Dutchgrown's LUI 13 stop on by...
"I just fed my girls... what went in was pH 5.5 nute solution, with a final EC of 1.4
What came out varied a bit.
-On what I'd objectively call the two "least healthy" plants (one of them being that yellowed one from a week ago), the pH was 6.1 and EC 1.9 on one, and the other was actually a different strain, but the pH was 6.3 and the EC was 2.0.
-On 4 other random ones, the "average" (I collected it all in one tray) runoff was pH 6.0 and EC 2.7. These were fairly healthy overall and just showing some yellow leaves at the bottom, which are definitely N deficiency.
-On another set of 4 randoms, the pH was 6.3 and the EC was 2.4. These also looked pretty healthy overall (no signs of nute burn) except for some yellow leaves at the bottom.
I've become convinced that I have been consistently underfeeding with N for a few cycles now, which I'm hoping I corrected with this feeding (double what I normally give, up to 20ml/ 1TB + 1tsp, per gallon)."
So, Tac, none of them were as high as 3.0, although a few were close... but that's with the tea going in. I went ahead and fed them because I had a lot of leaves showing N deficiency and the tea was ready... I'm thinking on Friday (4 days after that feeding), I'll check the EC on a few of them again with just plain water... what do you see in these numbers? Anything of value?
