Lockout? Can I remedy this late in the game?

clw1030started grow question 4 years ago

I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?

You can although the leaves will never correct themselves. Looks like a micro lockout caused by too much PK. Boosters are usually to blame (like a 0-10-10).

depending on the hydro you might be able to do a flush if you are doing Dwc or aeroponics where the roots are only suspending with o2 and water. then you could do a quick 24 hour RO flush then go back to light feeding

Leaves turning yellow and dying I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

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?
