Nutrient burn from Fox farm soil?
Ksouth1started grow question 4 years 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.

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 🌲🌲🌲👊

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!7 months ago

Upward curling leafs, burned tips, 2nd week of flowerSo I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/.
And some fading on some lower leafs.

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
