Just checked the ec of the last feed and it's at 1, I knew it was low cause before i posted here I had a feeling I was over feeding so I mixed up some 50% nutes

Should I give one more feed of low ec then bump it up to 1.7-1.8?

id keep them on around 1.4 for a week as they are showing nutes issues then you can bump up to 1.6-1.8.
