Hello once again,
I'm posting an update of my first grow and also a question, if you could be so kind to help. I've read that an upward curl on the leaves along with some yellowish spots could mean a Nitrogen deficiency. However the plant is a seedling and I was advised not to use fertilizers until Vegetation starts, what should I do and are these really signs of Nitrogen deficiency? Thank you for your time people!
