If your tds remains stable and have a downward trending ph, it sounds to me like you have a strong reaction between your nutrients looking for equilibrium at a lower ph. The byproducts of these reactions are most likely insoluble and therefore the plants start to show deficiencies. I would suggest trying to eliminate one nute at a time untill the problem goes away. Also, oxygenating the water speeds up these reactions, sometimes.

@DTaro Hi mate I think it could be taking up the water only and leaving the nutrients & salts behind in a higher concentration thus lowering the PH so quickly just my thoughts 👍

Thoughts on adding GH FloraBloom 0-5-4 1st time grower here- Good idea to add this nute to my almost 4 week old autoflower top-down? I'm using a wicking tub with ocean forest potting mix, that has a layer of fertilizer more rich in nitrogen. They seem happy, would hate to overdo it. Haven't watered them in 2 weeks.
