Is it okay if the first leafs develop and then the cotyledons start to develop unevenly along with the other 2 leafs that sprout from the stem after the first ones?
Well... the cotyledons ARE the first leaves... If what you were asking is it normal for them to be round instead of serated, then yes. I guess I don't understand your question.
i may be very very stoned, but that Q is still a head f**k to me lol, can you post a pic or re-phase that Q, but as mentioned above the cotyledons are the first leaves, then you will get serated ones after that, anyway its quite common for 1 of them to be bigger than the other, doubt thats what your asking lol, ditto to the above post: I guess I don't understand your question lol
