Brown spots on seedling

First of all awesome to see someone not saturate the whole medium so bonus points for that right off the bat though I fear it was still a little too much by looking at her that would be only reason the leaves would be drooping down so much as for the brown spots that will probably be a side effect of the water but it could be a cal mag defenacy though very rare i will give same advice i give to most growers when it comes to seedlings they are very tricky things to work with too much or too little can land you in massive trouble though often the best thing to do is just leave it and let the medium dry out and then water abit less but it takes a very experienced grower to grow a perfect plant from start to finish I dont think ive ever done it from seed and ive cropped many plants over my 5 years of growing its very common and in no way let it deter you the most powerful tool we have as growers is patience and if you use that my friend im sure you will be fine :) best of luck brother 👊
