I have a Big Bud auto that’s almost 7 weeks into flower. Buds seem to be be growing still but my water and nutrients is going in at 5.9-6.2 and my run off is high 6’s right at 7 the last few feedings. The leaves on the upper canopy seem to be lighter than the ones on the bottom should I give her a good flush or let her do her thing? 3 gallon fabric pot I’m Happy frog soil. Mega crop 1 part with pk booster Bud Explosion. Been feeding a gallon every other day. Is she showing signs of deficiency or just fading because she is close to finish?
