Noticed that there was a few light patch’s starting to appear on a couple of the plants, went away for a few days came back to looked like holes in the leafs. I was thinking calcium but also I’ve been using silicone at 0.5ml per litre I stopped using that a couple of waters ago and just wanted with water ph 6.5 and they seem to be a bit happier. Gave the compost tea at 500ppm. Transplant into 8 lt pots next week I think. Other than the few plants with patches they have done very well all topped on there 4th node.
