I have a number of hygrophila pinnatifida and they all have black spots on their leaves. Is this down to a nutrient deficiency or toxicity ? I'm been EI dosing for 2 weeks and these black dots have appeared in the last 4/5 days. I'm confused as I've read it can be either a deficiency or too much nutrients ! Or maybe co2 deficiency ??
Any help as I don't want increase EI and make it worse or vice versa !
Thanks as ever
