I feed them once a week with Foxfarm Tiger Bloom and Big Bloom. I water them as needed. I added some Calmag and humic acid thinking it would help the plant heal. I usually water with spring water but my last few was with tap water.1) check you're ph, if its good then eliminate the possibility.
what is your feeding program/frequency ?
Thanks I'm going to grab some spring water and run just that through it and see if that fixes it.I use well water too, my first guess is your tap water change coincides with your plant issues.
ph is a likely culprit assuming you got lazy like me on well water, and dont bother...with the tap either
