Nutrient burn from Fox farm soil?

Ksouth1started grow question 5y ago

Has anyone else ever have a sativa auto get nutrient burn from fox farms ocean forest soil? Gave it the first dose of GHE Flora series bloom nutrients at 1/3 strength only once and that was around 10 hours ago. Didn't see the burn on the tips of the leaves at the bottom.

Ksouth1answered grow question 5y ago

had the nutrient burn from the soil only. My runoff pH was fine and I only gave it 1/3 strength of the recommended dose for what it says to give for first week of flower for marijuana last night. It was the only dose of nutrients I gave in 5+ weeks. So I know it isn't from what I added. I only wanted to see if anyone else had experienced anything like that. But it seems that it is somewhat common. Will use nutrients very sparingly but not for a week or so. Thanks for everyone's time

FF Ocean Floor soil is very nutrient heavy (hot). When I first started using it I had nute burn constantly. I then started to just feed them PH water for up to 5 weeks with no burn or deficiency. If you do a light flush and then feed water only you should be fine. I learned that less (nutes)is best when using FFOF.

Is your run off ph in range. Would be first thing to check. Substrate ph might be going out of range plus a good run off washes out salts from used up nutrition. Good luck and happy growing 🌲🌲🌲👊

I have black spots and burnt edges on a couple leaves. Some of the leaves are also curling down which I'm guessing is too much nutrients.
