    Your guess is as good as ours..we really need a lights off pictures (with the colouring)..as we need to see the plants natural colour (or as natural as possible)

    Mix up A 1/2 teaspoon Espon salt to 1L of water, it might help next time you water. JMO

    O yea, it is common, just needs A little Cal mag, which you can get from the salt. Usually A couple of watering and it will be green again.

    Next time you feed and water, just add the salt then, or you can just do the salt by it's self, if not ready for food.

    its mg deficiency which is very common under led, you need to up the temp to 28 to 30c and give a drop of extra mg in each feed,

    That's interesting regarding the temps Forest, could you explain why the increase to 28-30c ? (I'm genuinely interested)

    ill try im not great at explaining, ive been growing under led for some years now (i make my living building grow lights these days) and have used all the kelvins and had many cases of what i now know is mg def, (dont chuck calmag at it ) its to do with how the led grown plants use more mg , and it is to do with how they transpire (right word?) if you up the temp to 28 to 30c they can transpire more and process the nutes in a better way , the plant will green up in a few days, sorry its not a more technical answer, my memory is bad these days.

    i know it , but my recall is terrible , sucks to get older!

    a quick google on the subject throws up a few threads with explanations in and some with diff theories ,

    i like the gold lable mg, liquid and easy to use, if you throw calmag at it like lots do, that leads to: to much cal locks out mg so u can get in a bigger mess
