Plant Problems, Please help diagnose

  1. I've got some plant problems and was hoping someone could help me identify the problem. This one is doing good overall, but it's slightly yellow on th top growth with green veins. I think this is a iron/magnesium deficiency. I checked pH, it's below 6. Might also be nitrogen deficiency.

  2. This one has very thin leaves, is yellow on top, and it's growth is compressing. I think this looks like a zinc defficiency.

  3. This one is yellow like the others, but it also withering away on all the leaves, from the tip in. Looks like nitrogen deficiency, but do the leaves wither like this becuase of nitrogen def?

  4. This one looks a lot like the first one. Yellow leaves, green veins, and a little leaf wilting/browning. Any help?

  5. HIGH All, I don't use rockwool and have never had overfert, overwater, or PH problems JIMBO33 so I won't be much help.

    Sounds like you hit the nail on the head with your own diagnosis though.

    One if the best abuse charts out there.
