You’re fine😂 i know these things can be stressful, but let’er pull through, as tuankt said, could be fly poo, could be dirt, i wouldnt be concerned, the plant itself looks a very nice green

Check under the leaves, if there is spidermite they could be hiding there. If not, don't worry it maybe just dirt or dust 😬

Try taking a cloth dipped in some water and wiping it. That black spot could be caused by a fly or a leafhopper

Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

Hey friends, can you tell me what this could be? Should I be worried? It seems to be doing fine and it's the only leaf with spots, could it be due to some water accidentally falling on it? Thanks
