Plant is 71 days old, 25 days after 12/12 flip and started yellowing about 2 weeks ago
She gets Canna 13/14, Cannaboost and Plegron purezym every other watering with one day in between watering. The lamp is about 60cm (23 5/8") above the plant. Buds are rather small and with alot of space in between. Because of fluctuations in the pH (6.2 going in, 6.7 runoff), I’m suspecting a nute lockout. Would a good flush solve this, and does the plant look like it can be saved?
Her scrogged sister on the other hand, in the same type of soil and getting the same nutes but under cfl’s, seems to be doing fine
Any help appreciated, folks, and thanks! @Countryboyjvd1971 @bob31 @Myfriendis410 @Nug-bug @Screwauger @DoomSack @daz49 @dbrn32 @Covertgrower
