I think I have nut issues?
OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

Leaves still goes yellow after flush with pure water 6.5pH, then only water with Biobizz Fishmix and last time all nutrients but 50% of recommended.
After last question with those symptoms, I flushed her with pure 6.5pH water, then next time started to adding only Biobizz Fishmix, and another next time I started to add all nutrients again but 50% of recommended. Buds, the white ends of the flowers begin to turn brown as well.

1st grow yellow leaves and brown spots
Last two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(

Spots on leaves
I'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue. Still look like PH fluctuation?

Nutrient lockout?
Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!

Alright peeps, here's one for you. Still don't know what it is. Pictures attached to Week 9, Veg. This has been occurring since week 3. There has been NO spread, it is always localized to only 1-2 leaf blades and she is not stunted at all (largest girl). Please PM for more info

Nitrogen toxicity mid-flower
So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

Leaves are turning yellow from the bottom up and I'm not sure if it's the natural death of unessery lower leaves or a nitrogen deficiency. It's not a ph problem. Thoughts?
