Update: plant still looks really sick! I’ve given it a couple foliar feeds with a light Epsom salt solution, but I’m not sure if the originally affected leaves are just dying off, but it seems to be even more affected.
Any idea what I can do to remedy?
I’ve fed with flora micro and flora bloom with deionised water, and a couple light foliage feeds with Epsom salts , other than that I haven’t done anything different. No more tap water either. Ppm of water is 004 to start, then around 35 once added nutes, the run off is around 780ppm. PH around 6.3.
Edit, I also sprinkled a tiny amount of iron sulphate on the top of the medium. A tiny sprinkling only before feed.
