6 weeks into flowering, no yellowing leaves.

OK, I have a question, when do the leaves turn yellow? i am curious as I switched to Monster Bloom, 0-50-30, and none of the leaves are turning yellow or even a hint of yellowing. I was using Jacks 15-30-15 up until starting flowering, and stopped at the introduction of the Bloom nutes. Also the spots on the leaves are not mites; that particular plant has some form of issue with spotting on the leaves, a yellowish color spots.

i think it prolly depends on the strain but u got at least a few weeks to go by the color of those hairs

Leaves near the bottom of the plant yellow and fall off sometimes. It's the circle of life.
