No im telling you that
if you water with 2.0ec and your run off is 2.2, they are being slightly over fed
if you water with 2.0ec and your run off is 1.8, they are being slightly under fed.
if you water with 0.1ec, your run off reading is useless because it cant be lower than 0.1ec.
(The run off of a previously fertilized substrate is always going to be higher than the plain water. Getting a reading of 2.0 or 4.0 is useless, you would only be guessing as too how much under/over fed they are) (However 4.0 is very hot imho).
Feed the plants with the exact same mix twice. The second time take the run off reading. If output is higher than input you are feeding too much, if its WAY higher, you are feeding WAY too much. The specific reading is irrelevant, its the change from previous that is important.
Im pretty sure i already said some of this, but i (re)use coco (90:10 fine coco:chunky perlite), in smart pots and 5Gal buckets, vertical lighting during flowering, on flood tables, using a recirculating reservoir, in tents, and normally use 5+8.
@ 6+9, my ec generally rises, and the girls seem a little too dark (thats why i adjust the micro [containing N] more [percentage wise; ie 1/6th less micro but only 1/9th less bloom].
This is what works in my environment under my conditions.
Im pretty sure 4.0ec is way way high. I had an AK-47 that was taking 2.8-3.0 before i understood ferts a little better. The AK did just as well @ 2.2, saving me $ on ferts.
