A flushing and correct PH'd nutes...most micronute problems aren't from there being a lack of the nute - 99% of the time it's just PH or lockouts from other nutes/poor water quality.

As the sandman said. It looks like a ph problem. Alkaline nutrients are less avaible to the plants when the root environment is acid, and vice versa. You call that a lockout, when the plant can't assimilate a nutrient even though it's there. I'm guessing a lockout of an immobile element, possibly magnesium. What is the ph of your nutrient solution, and the run-off water?

not sure powdergreen only my second grow allmix soil its in so been told it should be good for 2-3 weeks before we give it nutes not sure about micro nutrients though we have been having a prob with temps this is what happened to our last lot
it happened to these ones to but we lifted the light and repotted and all looking ok now we have 400 watt hps it is bit far away but worried to put closer in case we end up frying them again do you think they are stretching a bit to much

How are you ventilating your growspace and are you cooling your light?

we have got a small fan fitted above door bringing air in as for cooling the light no what would be best way to do that and would this let us get light closer

looks like zinc, keep in mind excess phosphorus will do this and you likely have zinc still in your soil. Otherwise just a plain zinc defeciency. Mg defeciency rarely shows itself first in new leaves, usually the middle of the plant, but zinc lockout / defeciency will show it on the top leaves first. Hope it turns around and you can fix it, the old leaves will stay the same but the new leaves will be green again.

Fitting a piece of glass to your light would let you get it closer,seperate the heat from the light. Or another fan blowing across the light to carry away some of the heat.
