Finding my way to Citrus

Citrique #5 is slowly coming back into optimum growing zone. She was fairly stressed for the last 3 weeks and showing red petioles and stems. There is a slight yellow tinge to the leaf color compared to the other clones. Like last time this happened 2 months back, I upped the nutes and grew through the redness stage. Optimal nute zone is only a minor nute adjustment away it seems. I am often surprised at how subtle weed sensitivity can be. Looking for canopy to be 12" deep before switching to flower. At least 10 days away would be my guess. best wishes to all my grower buds.
