Just by the leafs looks like a magnesium deficiency. But the whole plant must be taken into account...

That is a magnesium deficiency, i see the tip of this leave pointing down, which suggests watering issue. But... Hard to tell w/o seeing whole plant and situation. So could be too much water, could be not feeding calmag while growing under LED, could be PH that is too high or low, preventing this. Let soil dry, do a foliar spray with some calmag.

Maybe nutrient burn or?My biggest plant has started looking a little sick, have a feeling it may be some type of nitrogen toxicity? Maybe it’s just got some nute burn? I have flushed it out and will leave it be for a few days and hopefully it perks back up

Yellow bright new growthNew leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?

Thanks :)
