Yellow spots on leaves

Chr0nusstarted grow question 3y ago

Noticed yellow spots on one of my leaves. It’s just on one plan (just one bottom leaf). Don’t know if this is cause of water being on the leaf or something else. Might just cut the leaf but I wanna know what it is 😅😅

You need cal mag. The fade in-between the vains is mag. the spots cal 250-350ppm feed. As you've both issues. Id just get a cal-mag. Epsom salt will help if you have no CM on hand. If you've a female at home. As has she any unscented Epsom salt. While you wait on a calmag.

Possible toxicity or deficiency?I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

Yellowing plant Why is my plant yellow? I thought nitrogen or magnesium or PH. But i tested everything and it is still yellow. I tried flushing and using no nutrients but didnt help. PH is good, tried giving extra nitrogen and magnesium. What else can it be?
