Burning Tips and Yellowing Leaves
Sweet_Smoke_84started grow question 3 years ago
Hey, as you can see, this week ( flowering week 5 ) was a lot of tip burning and yellowing leaves, which is a bit frightening. I don't think I over dosed the nutrients, and I gave them regular treatment as every previous week. Any idea where it can be coming from ?

Hi there,I am not very sure but have to agree with gmslave.It looks like potassium deficiency.But before you take any corrective action, make sure your water pH, ppm(EC) and run off are in corrected range.If you are growing in soil, keep your pH around 6.0~6.5 for both of your water and run off.Check run off ppm and compare how much different between in and out.Good luck and Happy Growing... ✌️

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Sligthtly Yellow LeavesI'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Should I cut off yellow leaves?Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?
