Burn on leaves
Newfie80started grow question 6y ago
I have been getting the same problem late in flower now as the last grow, not sure what I’m doing wrong. Always getting burn on leaves bad, only giving ph water to naturally flush a bit for last couple feedings, so I’m not giving nitrogen to plants only some bud candy

looks like your girls are screaming out for calmag. The rusting will have begun mid flower I expect?. if your using led lights and/or coco , tje loss in the magnesium is mainly these culprits on indoor grows. It 8s made worse during flushing as any goodness is washed away as you leech the soil/coco etc..
Always a good idea to have some calmag handy as you go into flowering as this is when the load is heavier for mg. I use it as a rule of thumb now as led is known for this issue..this coukd also be why they haven't fattened up more too.

I'm thinking it's a phosphorus or magnesium deficiency, late stages too. I would suggest increasing your pk nutes, you can leave a small amount of N. The flowers look quite small and you're only in week 6 of flower and they still have some time to go and much more need for P and K nutrients! Give them a light flush, and increase flowering nutes! Good luck, I'll follow 🌱👍

If you had this in a previous grow as well, it could be that this strain is quite sensitive to mold or that there were still remnants in the space. I see some powdery mildew here and there if I'm not mistaken. Did you have issues with this? The problem is only at the tops. Most burning issues from nutrients start at the bottom of the leaves. It could also be that the lights were too close or that this is a severe calcium deficiency. Check out these possibilities🙂
I hope you can resolve it🤞
Good luck!🌱

Looks like a potassium deficiency. I would always check your run off ph first for lock out reasons. Good luck and happy growing 🌲🌲🌲👊

Big problem: burn tips and spot on LeavesHi dear friends!
Leaves from this VANILLA KUSH are crispy and they aren't "smooth." since last week I didn't gave any nutrients but only ph water.
Syntoms may be a calcium deficiency but I don't know if it is the problem. Please, what I have to do to? 🙏🙏🙏
