Discoloration on leaves - Light green

Well i've posted this problem in the past..... And got a few answers, but neither of them worked the new growth even has little light green on them too. Does anyone know anything about what this is? And what might be causing it?

Anyone :\?

I'm using 10 27w daylight cfls, but 4 of which are fixated on this particular plant.

Hi G..., looks to me like calcium deficiency although doesnt look like a serious condition at this time... Check your water and nutes for ph.., then treat foliar with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency.
(Only mix at ½ strength when using chemical nutrients or it will cause nutrient burn)

I can guess Leaf margins are not curled-up noticeably. it might be N deficiency.

no its not

I have a strawberry cough plant that has the same genetic problem! I have solved this problem with epsom salts at 1tsp per gallon. But, it is nothing to worry about at your stage. Growth looks great and green, plant is probobly using alot of magnesium from the soil. I use Canna Terra Vega which has mg in it so I only notice the leaves during flowering when mg is reduced. Some plants are geneticly pre-disposed to this mottling of the leaves. Dont Worry. Keep a vigilant eye on them. Good luck ! thegrowschool.com
