What is up with my plant?! (Need help)

[Thiz420]

Hello!

Im pretty new to this forum and im getting really frustrated about one of my plants.
I have flushed it 3 times now and it helps for 1 day then the problem is back again...

Strain: Sour Diesel #2 From humboldt seed org.
Weeks in 12/12: Begining week 4 next Monday.

Problem?
Getting crispy,hard,crumbling leaves with brown spots/dead spots.

Neuts: Gold label.

Salt burn. Salts build up in the pot over time from the nutes you feed it and the nutes already in there, the more you let the pot dry,the cheaper the soil/nutes the worse the build up gets. Next grow use bigger pots or water more often. I use 30cm pots and have to give plants about 2 litres of hydro nutes a day in coco, flushing every 5th feed.

So really nothing i can do? Using 9 liter pots atm and 400W HPS.
Flushing wont help i guess?

After you've flushed them...what do you do? Just resume the same program as before? You should let your plant rest for at least a week or so under reduced light and then lower nutrients before you start them back. Follow BUDS suggestion regarding flush...

I have not feed the SD with nutrients for 1-2 weeks now. So no, i am not new to growing, just new to this brown spoting ect. Never seen this on my plants before. Will prob only feed the SD with water then in the 6-7 week i will give her some bllombooster and see what will happen.
