Critical showing deficiency or excess, anyone know how to solve it???

I think I see what it is you're worried about - but I don't think it's very much to worry about! Except for one or two leaves that have some markings on them (the marks may have been caused by liquid spilling on them and then slightly burning the leaves under your light?), I don't see anything wrong with this grow. I know you struggle for the money to do the best by your plants and if you had the money, you would get a better light perhaps or improve other conditions - but you don't have the money and you're doing the very best you can and you're having a very successful grow! I applaud you!! As they say, "where there's the will, there's a way" and you've found the way because you have the will. You are an inspiration, seriously! Do not worry unnecessarily here - there's really nothing to worry about! Good luck the rest of the way.
