Yellowing of the lower leaves during flowering is quite normal/common, but either add or up your P/K booster to help your plant, she will be hungry for phosphorous (P) and especially potassium (K) during flowering.

The damaged leaves won't recover, but it will prevent the other leaves from suffering the same fate.

Yellow spots on leaves
Are the yellowing spots signs of Leaf Septoria? I'm assuming it's more of a nutrients issue but have never experienced LS and wanted to get some second opinions.

First leaves died. Overwatering?
The first real leaves died from the tips. My theory is that this was caused by overwatering. Does that sound plausible? Feel free to check the diary for details (it's my first one). Thanks!
