Hi guys my leaves are yellowing and i think its nitrogen deficiency based on what people have previously told me since its the outside of the leaves moving in. this is an auto in coast of maine soil and i am using organic ammendments. i added bloom food(fish bone meal) about 3 days ago but only did half dose as before i did too much. should i just keep waiting for the plant to absorb the nutrients? or should i add some more food? or cut off the yellow leaves? thanks. this is the worst issue ive had so far i was hoping the leaves wouldve started greening up by now. i know its a very bottom heavy plant its only my second plant but next time i fully intend to top the plant during veg instead of letting it grow like this

That looks more like a magnesium deficiency.

Yeah it's certainly not a N def.
N def will start on the very bottom leaves as N is taken from them to feed newer growth.
Then it spreads up the plant.

Magnesium deficiency is usually solved with epsom salt. Either via roots or as a foliar if you want to it to act quickly. If you use more calmag you also add calcium, iron and nitrogen. Not the precision tool one wants.

Go with to the roots id avoid spraying anything if i can avoid it best to wait a day or two to see results vs spraying there is literally no need to foliar feed ever imo unless its cuttings then fair doos budThis is always helpful
