I water the plants with distilled water, ph'd at 6.2 and I add 1/2 tsp per gal of calimagic. This is happening on one old growth leaf on 2 plants.

From the looks of it, it looks like a leaf dying from not getting enough light which is completely normal. Hopefully, I answered your question and remember " Happy Growing".

Yellowing Leaves The leaves on one of my plants are really starting to yellow. To me, this looks similar to pictures of plants in late flower, rather than the examples of nutrient deficiencies. Have I read this correctly, or should I start worrying?

Feedback/checkpoint/thoughts Hi every1👽😌Started week 7 of flowering today. How do they look to you? Is there anything I should pay special attention to? I think I may have overfed or overwatered them last time - I’m not sure which one - which could explain the leaf damage. What do you guys think overall?

Yellow Leaves Autoflower Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?
