ive got super yellow leaves on like the bottom half of a couple of my mature vegging plants. im feeding them every other watering, about one-two times per week with some 3-1.25-1.25 nutes, soul synthetics. should i foliar feed the yellow leaves with this in addition to regular feedings until they get better?

yeah foliar feeding does give the plant nutes faster but i read that its not good to do for long periods of time because it makes the roots stop there uptake

It is more than likely that the yellow leaves will not regain their color. You would probably just be preventing more from turning yellow.

ok, but so its worth it to foliar feed the plants that have yellow in additoin to regular watering/feeding? they wont get nute burn right away?

If I had this issue, I would stop foliar spray altogether for a while, see what happens.
If the leaves are yellow and the stem is purple I would just take the leaves off.
