Nute lock out

3rd week of flower. The lower leaves are getting burnt tips and getting black/spots on them. Stopped giving them nutrients last week. Also stopped using lemon juice to ph down. Run off was 6.0 4 days ago. Yet when i check the soil its more around 7

This what the leaves look like and burnt yellowing at the tips

Get some advanced nutrients flawless finish and follow the instructions (use it for 1 week) and just continue flushing for another week or longer, thats all you can really do. It says to use it 1 week before harvest but I like to flush after using it too.

Edit: oops i didnt see you're only 3 weeks in, just flush with low ppm water til its normal.
