Hello. A few weeks ago, I bought basil plants from a store. Initially they were in a little plastic container, but I re-planted them into a 6" pot. They are growing okay, but before I mess something up, I wanted to check if there aren't too many of them in the pot I have now. There are 14 of them. They were all inside that little plastic container I bought in a store...
A few of those plants are very little, others are growing really tall (towards the sun?). A few of them have really strong stems, whereas others are pretty thin (although look healthy). Do you see any serious issues from this one image? I am only starting herb gardening, so I really don't know what I'm doing. I prune them once in a while and they already started bushing out.

With leaves that size they are a bit crowded, no room to spread apart, which could lead to a lack of aeration. I have to keep mine plucked a leaf at a time, but I dry the leaves, and mine are outdoors in a very humid area and subject to downy mildews and such. Yours look good, you are doing a fine job with them.

Welcome @truszko1

I think they are going to be way too close together to stay in a 6" pot. Basil can grow to be a good sized plant. That being said, I'd try to gently separate them and plant them either in individual pots (6" would be the smallest I would try) or plant them in the ground. They will do much better with some space in between them and make them much less prone to any diseases.
