#1 Severe nitrogen deficiency
White/yellow tiny new growth

Twisted pale new growth. (could also be K, Mg overdose)

Greenish nerves and yellowing of the older leaves.

Yellowing and death patchs on older leaves. The leaves die and falls off rather quickly. (Look similar to early nitrogen deficiency)

Most useful, has helped me identify a problem already

Glad it has helped already. It is with this sort of graph that one can use the dry salts more effectively.

For example, Java ferns, mine sometimes get pale leaves, obviously magnesium issues.. :)

  nice one ghostsword this makes identifying deficiency with plants much easier to spot and also explains in easy steps the lack of a particular fertilizer to combat the situation
