Brown spots on one seedling
FatalFarmerstarted grow question 6y ago
I noticed some small brown spots forming on one of my plants leaves, not sure what it is, maybe early sign of cal deficiency? The other plant looks nearly identical with out these spots, any advice helps although it could be too soon to tell what it is...

Everything looks good to me. They shouldn’t need any notes at this early stage and are susceptible to burning very easily if you do choose to. Those leaves will be nothing meaningful in a week and they look fine anyways. Good luck

From the color of the spots, I would say it's more of a Calcium deficiency, but I'm not sure.
Calcium deficiency spots are brown with more intense edges (like they are burned).
Magnesium deficiency spots are brown, and the areas between the veins take on yellow tones.
You can wait a bit to see how the spots develop, but if not, you can buy a Magnesium/Calcium fertilizer and whatever it is, that extra boost will fix it.
Hope this helps :)

Could also just be water spots, but it seems rather dark brown/orange and symmetrical on both leaves

Dark green leaves in meringueIs my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?7y ago

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

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 👍😳
