Salts building in your planter, causes lockout. Ph out of whack also causes lockout. Check both.

Hi everyone. I am rdwc w/4 plants near end of flower. This plant has always been unhealthy. However this is a new twist. As I said rdwc, other girl are groovy, so it is what it is but my question is; what is it? Genetics?

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

Browning, curling of Green Crack leaves
Is this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

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.

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Brown spots on the leaves
Hello, everyone. After replanting, this appeared on some of my flowers. I think it's probably stress after replanting, but I'd rather ask you more experienced ones. Thank you in advance for the advice 🙂
