Всем привет .. что это может быть? Удобрения не давала 3 недели. И могло ли это быть причиной питательного вещества? Что может вызвать желтые пятна на листьях?

It’s a Calcium deficiency. There’s many reasons for a Calcium deficiency. An excessive amount of ammonium, potassium, magnesium and/or sodium in the root environment. The absorption is curbed mostly by ammonium and least by sodium. Problems with the evaporation caused by an excessively high EC value or by excessively high or low relative humidity. In soil, using tap water, a proper Calcium deficiency is extremely rare, there’s plenty enough in both of them.

First make sure your run off ph is in range. A lot of times it is a ph soil issue and not a true deficiency. Roots just can't absorb it. If ph is ok it is a cal mag fix. Or even just magnesium. A little Epsom salt will do if no cal mag handy. Good luck and happy growing
