Fox farm ocean forest. Fox farm liquid nutes, with micronute supplement.

I thought I had a salt lock out, but I flushed my soil and the symptoms got worse.

I intial thought it was a cal deficiency, than mag and than zinc. Now I’m thinking it looks like a potassium deficiency but it’s worse up top which I understand isn’t typical for a potassium problem

Okay that strengthens my belief that in my be K, I thought if was lower growth that’d be hit. I guess my main concern is I don’t want to keep trying to add nutrients and just end up contributing to a salt build up and locking other nutes

Salt lock out ???
Probs started off as ph issue . That's been going on for a while and just decided to ask now ??
Multiple long standing issues there .
To late to correct . Waste of time and money giving anymore nutes . Clean here out and enjoy

The curling up, and other symptoms look like a phosphorus def... which could be caused by ph lockout as well. P excess will lock out other things like Cal and Mag, Zinc and Iron.

Generally if there is multiple symptoms that pop up like that it tends to be a lockout or ph issue. If youre getting multiple deficiencies it tends to be one of the two. Id start heading in the direction of what this person said, but at this point it might be worth it to go a little longer and let the buds get as big as they can and chop her down. Use what you have learned and try and prevent it on the next go. I wish you luck OP

Thanks a lot, gonna give very light P and K through fox farm Big bloom and if she reacts well I hold a few or so on starting flushing and harvest.
