Slight burn. You're feeding MORE than the manufacturer recommends and manufacturer recommendations are notoriously over what your plant wants. Dial it back a bit, see where 4mL/L takes you after doing a water only feed or two.

Well I added 280 ppm nutes and she showed signs of burn and the leaves dropped. I lowered the ppm to 200. Is that good enough? It's a very small amount of brown around the edges but I dont want it to get bad.

I see that there are yellow leaves with brown spots, the tips of some leaves are "burnt", and I also could see very small flies I think they were "Fungus Gnats" and that they may be the cause of his yellow spots, am I right? and how many weeks would you wait for the harvest? thx!
