First week of flower and this starts happening. I flushed with 1 gallon r/o water hopefully it doesn’t continue. Anyone knows what deficiency is this?

It look like light burn or a micro nutrient deficiency (magnesium, copper etc). If your lights are the proper distance and your feeding the plants a well rounded diet, then i would double check your ph pen is accurate. Recalibrate it if possible. You may be having ph swings too low or too high. Happy growing. ✌️

Brown yellow leaves?Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

New grower with questions about burnt tips, browning/scrunching leaves and some pale/yellow spots!I noticed Quick One had issues with burnt tips and discoloration by the end of week 1 and 2, what could've been the issue? Apple Fritter is looking sick, brown spots, what is that? Easy Bud and Quick on have slight yellow/paled spots on their leaves, only 1-2, is that normal?

Bottom Leaves only looking worse for wear Hi, does anyone know what's causing some of my very lowest leaves to become like this? They are still attached to the plant but fall off really easily and look like they've had the life sucked out of them. The rest of the plant looks relatively fine.
