answered grow question 4y ago
it could very well be lack of calcium and magnesium. you can google "comon lack of nutrients cannabis plants", from the examples shown, this seems CalMag deal.

Leaf tips turning yellow or brown
Is it normal for leaf tips to start turning a different color? I thought maybe it was nutrient burn so I flushed it a few days ago. I’m a total noob with growing so I’m not sure if they’re supposed to get better after a flush.

Yellowing/purpling leaf tips outdoors
Im experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?

I water my plants everyday , however I have mixed my nutrients “ph perfect grow, micro, and bloom” in with my water only the appropriate amount given on the bottle. Should I be using water with the nutrients everytime I water or switch it up with plain water as well?

Would putting off my first feeding for a day or two do this much damage to the plant? I've given it 2 feedings since then and hoping it's on the right track as the new growth is nice and green.

What's wrong with lemon cheese? Is it overfed? Drain showed me 800 ppm and after flawless finish drain became 600ppm. Or is it my tap water (300-400ppm WITH FILTER)? Should i get reverse osmosis?

What is that?
Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6 Increased light intensity to PPFD 600. This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick. If it's a light burn, why not on upper leaves?
