My very first Grow

A big week of stress on my side I admit ^^ 😬 Since my questioning at the end of last week, thank you for your enlightenment, indeed, the lack of nutrients in my pot and especially nitrogen (N) has caused the lower leaves to turn yellow and die. 😞 It was mainly due to the lack of input on my side, but it would not have happened if my companions had not drawn from my soil, so the first mistake would have been to have let the alfalfa grow too long and pump my nutrients from floor. And my lack of watering and underdosing of my compost tea didn't help. With the advice of elders :) ^^ I urgently provided a compost tea boosted with nitrogen as well as a foliar treatment with boom boom spray from Bio Tabs (by the way don't hesitate to go see my new diary on Natacha, the white widow ahah, who she will only be fed with the complete pack from Bio Tabs) 😃 After a few days, the leaves turn yellow and dry up so I cut them and return them to nature in my compost eheh. Now they look better and a little greener than before. 💪 Well all his adventures from my beginnings obviously impacted the future harvest, with less vegetation, and less full heads, but it's to do better later that we make mistakes haha ​​:) Another very crucial information that I learned and you will take me for an idiot ^^ but I was watering too quickly and with too much quantity, which had the problem of bringing all the water down directly. I learned that the substrate therefore did not have time to capture the water and gorge itself... This problem is quite uhh how to say, serious, since my substrate since the beginning (6 weeks), had not not enough humidity then the water was in the box, and as I had put 5 centimeters of clay balls in the bottom, the substrate had no way to pump enough water... 😭 Finally you understood, it was the swimming pool LOL, and with the swimming pool I had the right to a lot of seaweed... After having had the information, I hastened to clean everything and now I water little by little and over the entire surface! One more thing learned ! Check ^^ On the penultimate photo, you can see, I have the impression that it's a burn on the leaf, only on this one, I think that with the Boom Boom I must have insisted too much on this place, but nothing serious a priori ! 😊 Thank you for reading me, I talked a lot, I apologize, and above all you can tell me in the comments what you think of this new MACRO lens which normally will provide better photos 😎
