I just noticed the yellow tips on leaves of two trees. Coincidentally, these are two that haven't had any new leaves grow since summer, though the lemon bloomed heavily. I've probably been fertilizing them too much because I mixed the same concentration for all trees, most of which are growing rapidly.




I may just repot these early. I was planning to do them all once I can move take them outside sometime next month. I've been watering with very hard well water all winter because my rainwater buckets are always frozen solid.

Also, I ran out of the low-urea fert a couple months ago and have been using the rest of my Miracid which according to the manufacturer contains up to 0.9% biuret.
