This week I was using nutrients that I measured free-hand, which was as it turns out a pretty stupid idea as the leaves did get some toxicity. However have now flushed with some plain PHed water so should be fine once it's burnt off the excess. Unfortunately biobizz don't seem to have a nutrient schedule for flowering for photoperiod so I'm not exactly sure how much to use.
Next grow don’t use as much nutes looks like a lockout needed to flush with plain water as your pot can’t get the food out the soil if you haven’t cut it down already. why are you feeding like that ? only really need 3 things your useing as nutes depending on your soil the rest is a waste of money. Good luck on your next grow.
@Growium, yeah, I didn't think I overfed but not used to the way that photos grow. Totally agree with you though, and I only used plain water from like week 10?
