Leaves curling upward, burning tips. Light green and dark green on same leaves. 30 days in veg, I got a new light. I’m sure I got some light burn but since then lights have been moved , ppfd, and vpd have been controlled. I’m organic in amended compost/coco...what do you guys think

I had a problem similar and turned out the ph of the medium was out. Not saying that is the issue, just looks similar. I flushed mine with PhD water to 6.2 and then finished with a light feed, the bounced back after a week. Just a suggestion

So you flushed it until the runoff was 6.2? What was the pH of the water you flushed it with?

I been flushing with RO water the past 3 weeks. I just fed it a mix of RO water molasses and liquid seaweed. I got smell on my leaves now. I hope that’s a good sign. Things are turning green that we’re once light green
