I started a purple haze auto in coco. Using guia green all purpose at 3 tbsp. Per gal. And power bloom at half that. I started them in 5 gal. Pots. The tips of the leaves were starting to curl down. I’m pretty sure it’s nitrogen burn. What should I do? And what should I do differently next time?

The newest growth looks good. The tips of the fans are a bit dark but not burnt at all or turned down as seen in the pics at the link. I'm not sure that's a nitrogen burn. Typically you'd see darker green with a shine to it along with clawing. That plant looks like it's healthy to me. If you're confident in your grow set up, lights, temps, PH, RH, etc. and still concerned back off the nutrients to 1/2 strength for a feed or two and see what your plant tells you. Then decide what to do differently if anything next time.

When considering issues with plants, I have found three time when I shouldn't judge: just after and just before watering, and just after the lights come on. See how they look halfway between waterings and the on period of your light.
Also, if they look odd once, keep an eye out but don't fret. If issues seem present for a couple days or after a couple waterings, consider fretting.Visne explicare?Comment
