whats wrong with this plant?

I've never seen anything quite like that... but it's not a Mg problem. It looks almost like your plant has been attacked by fungus.. not sure though... potassium helps the plant fight off infections... I'd start looking at that... can't offer any more help, sorry.
For reference, the Mg def shows a very clear pattern of paling between the veins rather than a sort of random necrosis.

I feel better knowing I'm not the only one confused.....it is the randomness of it that seems so odd; that's why i wondered about spraying.....hope changing the ppms helps...

You can get Serenade at Walmart... certified organic... cheap... bacillus sp. beneficials... works great and even if you don't have problems it at least won't HURT.

I have what looks like that too. Or similar. Hell I dont know, but I'll try to post a pic after a while. My humidity is only about 30% and I didnt think I could get any fungusy type situations.

Could be manganese.

Manganese Helps enzymes break down for chlorophyll and photosynthesis production, as well as it works with plant enzymes to reduce nitrates before producing proteins.

Having plants that are deficient in manganese can turn the young leaves into spotted (mottled) yellow and or brown areas on young leaves. Dead (Necrotic) yellow spots form on top leaves, while the lower older leaves will or may have gray specks and or spots. Symptoms can include yellowing of leaves while the leaf veins can stay green. Can also produce a chequered effect. As the plant gets newer growths the plant will seem to grow away from the problem, thatâ??s why the younger leaves may be unaffected. On the top of the leaves, brown spots can appear. While the severe areas of the leaves turn brown and wither. Parts Affected by a Manganese deficiency are: Young leaves.


Too much Manganese in the soil will cause an iron deficiency. The blotchy leaf tissue is caused by not enough chlorophyll synthesis. Your plants will seem to have very weak vigor caused by the excessive amount of manganese.
