No offence here errbody, but is it just me or does that OP lady not look very happy at all? Apparent nitrogen toxicity, foxtailing and general poor appearance?
Again, not to step on toes here but why is nobody helping with advice and honest opinion?
Been there, won't deal with them. Total klomp p**se. I wouldn't trust them to do my laundry, let alone prepare a package. I would have gone there and taken a new unit.
As said, it's sad they're dragging good products' rep through the poo. Name and shame mense. I've taken the liberty of attaching a loc of their retail store in JHB South.
All this being said, I've had good experience dealing with hydroponic.co.za.
If you have already flushed her theres nothing to do but wait , if new growth is still clawing after she has dried her pot you will need to flush again. If new growth is fine carry on as normal . Old leaves will not heal themselves so new growth needs to be inspected
