Sulfur toxic.?calcium def.?zinc def.?

OK so I am going to upload pics from my phone I just wanted to create the thread before on my comp so I could just add them...but a little back story....did my own little version of subcools recipe, tested ph and it was spot on.....every thing was growing amazing! Well 1 strain I had to add epsom salt it was "praying" for mg.....other then that perfect....so now my auto the newer leaves tips are burnt/brown and have the claw, but the leave size is such a huge different in size to the bottom half (that's why I'm thinking zincdef.) And then I'm doing research into it and I'm realizing my other plant, slow growth, bunchEd up and curving of leaves can be a multiple of things .....BLAH I'm so lost...yes I am new, but I've grown a few and never really had this much of issues...my mind is just fried from reading so much different def/toxicity that basically are the same damn thing!

So thank you in advanced, and please no smart ass answers I'm ready to rip my hair out as it is, bc I cannot afford to lose these!

I'm going to try nd take more clear and closer pics but in order 1 auto 2 shark widow

The best the pics will get, my aliment makes me very shaky so hopefully please try and look but the 1st and 2nd is my auto...it's dominant indica and the new leaves are such a difference and new growth tips burnt, scorched etc.. (using t5s and cfl's I have had them within 1-3 inches the whole grow the and raise accordingly never had a burn issue with my lights)

3,4,5 is my photo shark widow....it was growing good but now, very slow growth, the curving, and color fading....not just yellow but losing green as well?

I use tap water and out of all my grows I have never had a problem with using it, until now...
