leaf veins yellow

leaf veins and tips yellowish... problem?

its only the main vein on each leaf that is yellow the other ones coming off it are still green

post a pic ! It may be a zinc deficiency in which case you leach the soil the add a micro-nutrient or a nitrogen deficiency in which case up the nitrogen(you want to be sure or else you will overdose on nitrogen turning leafs dark green). In either case leaching the soil first is a good idea. Hope that helps.

thanks for the reply , will try leaching the soil... heres some pics

Now seeing the picture they look fine to me a little heat or light stress but not bad. Leach the soil anyways as leaching the soil every 2 weeks is great for the plants. (but who actually does this ? just leach whenever you can )
