There was quite a bit of nute lock-up to get a 4ec. Usually at this stage I would be running an ec of 2.0-2.4. If everything is going good I have managed 3.0 ec. After my weekly res changes I will only add water and only adjust ph. This way my ec either stays the same or drops. After the change I usually see a decrease in ec and ph goes up so I try to start a new resevoir at 5.8 and work towards 6.2 to make sure the plants recieve all nutrients. When I am near harvest I only flush for a week, but I drain the resevoir every day and add fresh new water till the ec is almost nil. Its a little more work, but you can flush without doing that. Just change the res at least once during the flush to remove the initial flush salts.
gronnh20 Reviewed by gronnh20 on . PH too low This morning, i notice that at least two plants had a coloration problem. No green in the center of the new bud. I checked PH, it was 4 ans EC 4 also ! I flushed the containers and i put new nutes. Do you think i should have give them just water with good PH? Or is it good now ? Fhydro Rating: 5
