What is wrong? Advice please

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

I’ve filled out a support ticket below and will try to attach some pics

Strain; ILGM Amnesia Haze auto

Soil in pots, Hydroponic, or Coco? Soil - Fox Farms Ocean Forest

System type? Not sure what this means

PH of runoff or solution in reservoir? PH is 6.5

What is strength of nutrient mix? EC, or TDS - Don’t know. I use Fox Farms nutrients and follow the Fox Farms feeding schedule.

Indoor or Outdoor - Indoor

Light system, size? - 900W full-spectrum LED

Temps; Day, Night - Day and night 75-78 degrees F

Humidity; Day, Night - 49-50%

Ventilation system; Yes, No, Size - No

AC, Humidifier, De-humidifier, - Dehumidifier. AC from the house

Co2; Yes, No No

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.

What do you guys think? @Countryboyjvd1971 @Myfriendis410

Have you flushed like fox farm recommends as well
If not it can be a salt build up
I would flush and check ppm of run off and ph


I have not seen any bugs, but I also have not flushed. I will do that


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.


OK, I do have sledgehammer. Should I flush with that or just ph’d water?


Fox farms recommends using sledgehammer. You’ll also need pH’d water, but a lot less than without the flushing agent.


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

I agree :point_up:️ with @dbrn32


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!
