So adding a small amount of coco coir to the top to stop algae gave me a problem. I checked the PH run off and it was slightly high 6.6 but not enough to cause major problems, one of the plants leaves had browning/ rust spots between the veins and the other plants had small spots, which I believe to be a magnesium deficiency, so I flushed all plants with 5ltrs of tap water (ph 5.5) then fed them the same but added canna calmag. I removed the worst leaves and prayed. That was yesterday and things don’t seem to have got worse. The mistake I made was not flushing the coco coir before I used it, thankfully I put a second drain hole at the very bottom of the bucket which is taped up, it allowed me fully flush out all the salt buildup that was in the reservoir. I’ve started lst on two of the plants the two least affected.🤞it’s sorted and we can move on!
