If scoured online to figure out whats goin on here but nothing matches quite right, plant was grand 2 days ago. She's getting plagron alga bloom and biobizz alga mic at regular strength. Ppm going in is around 600-700 and runoff is around 1500 on average. Ph of the feed is 6.6 and runoff 6

... need more info to diagnose mate, please go to the highlighted section above here and check out the patient info form; just c/p it into here, and fill in,... whole plant pics will help too,...
that could be a few things, hence the need for more info, but that r-o ppm is high, likely behind this mess.... symptoms look like nutessalt build-up burn,...

Cheers man, a had a friend come have a look and he reckoned nute burn too. I checked the plagron feed chart and it makes sense, chart says 4ml per litre for 3 weeks and then 3ml for 3 weeks, then back to 4ml. Which makes me think the feed is prone to build up. To make matters worse ive been feeding the directed 5ml on the bottle.... live and learn eh. I flushed her last night with plain water, ph 6'8 ppm 160, Run off, ph 6.3 ppm 1250... ill give her a few days to recover and see how she's looking. Cheers for the reply DR waira

Just a tip on flushing, soak entire medium let sit 30 mins then flush with 3x pot amount. The problem with just flushing without soak is the water doesnt absorb nutes or salt and just bypasses to exit. Then 30 minutes later you've got all nutes broke down and the only place for it to go is in plant.
