Hi there. I’m having a problem with my Amnesia Haze autos. Leaves are spotted and yellow. I thought it was cal/mag deficiency, so have been giving it cal/mag, but it hasn’t helped. The plant is 7 weeks old, and about 2 weeks into flower
Potassium maybe? But if you’re feeding the ff trio, they should be getting all macro nutes. Have you checked for bugs? The only other thing I can think of is your water quality.
After you flush and begin feeding again, disregard most of those older leaves as they will generally not get better. See what your new growth looks like.
Sorry @JuliaBelle use the sledgehammer
Definitely and use ph water
I flush using sledgehammer until i have runn off and then i let it sit for 20 minuets and finish flush using ph water
My plant looked exactly like yours i flushed with sledgehammer and comeback and now everything is good i had a nitrogen deficiency i believe but used cal mag with the rest of the fox farm nutrients and every thing is nice now
Looks like nute burn to me and as John said FF recommends periodic flushing (on their chart). I also notice that they use a VERY high TDS value when feeding in soil. With Ocean Forest you don’t need anything until flower and risk this very issue.
Something I do (and did yesterday) is to use Flora Kleen or Sledgehammer followed by running the garden hose for 15 minutes then after the pot has drained, water with PH 6.5 water to reestablish correct PH. Works great!
