White skunk

Hey friend your plants are looking good, i know that discolored leaves aren't the best thing but it usually only takes a couple small changes to fix. Definitely consider finding a way to monitor the ph, or find out the ph of your local water. Then yes continue using nutrients. With the buds where they are in this weeks photos they definitely look like they have a couple more weeks. You might be able to benefit from doing some foliar applications in the evening as the suns setting if you can't get the soil ph figured out. *but remember that even when the problems are fixed the yellowing or spotted leaves won't recover, but other leaves shouldn't continue to discolor.

I would hold off on nuting them for a while yet. Soil should have enough for a few weeks
