I have found my 100 litre autopot reservoir had quite a lot of not dissolved potassium silicate supplement. The filter also had some of it not dissolved that needed cleaning out. Specifically this: https://herbals.co.nz/collections/nutrients/products/potassium-silicate-supplement-goliath-nutrients
perhaps I am using it wrong. I was adding 1ml per 2litres each time I filled the reservoir.(half strength) I also found two autopots blocked up, not feeding due to potassium silicate. Will have to be careful using that in future.
Anyway, I cleaned out the reservoir and mixed up a fresh batch of 90litres worth of nutrients. This time no potassium silicate. PPM is 700 and Ph is around 6.0 after some ph down.
Besides that, seems to be coming along well. I will post some pictures on Saturday or Sunday.
