    Orange funk forming on one of the leaves on one of the plants? Sick node? Sick head? Sick leaf? Deficiency that will effect the whole plant? Where can I start to figure this problem out?

    Possible nutrient burn. Look on the back side of the leaves to make sure that you don't have bugs. If it looks like the damage started on the back then chances are it's some kind of bug. Usually there will be bugs back there too. No damage on the back of the leaves or about the same as the front? Usually nutrient burn. Flush with pH'ed water for a couple waterings.

    Hey there! I just found this for ya :) looks like it could be nitrogen. Is it your plant in vegetative phase? Could be potassium too... [​IMG]

    I had a manganese problem early past month and I fixed it with tomato fertilized I bought at Walmart, so act fast, don't let the sickness spread!

    I'm convinced it's the PH. My level is currently between 6.9 and 7.1

    Very shocked considering the sensei grow is "ph perfect"

    Yeah bud, definately try to lower the PH to 5.7-6.2, flat 6 would be great ! Are you seeing signs on any of the other plants ?

    PH problems usually first show as red stems.

    Looks to me like your pH is off. It's either that or a nutrient deficiency. If your pH has been out of range for a while, there's a chance your roots are locked up. Looks like that plant is a pretty developed one. Got to keep the pH between 6.3 to 6.7 to make the plant happy and roots open so it can take in what it needs. Nute burn always shows up as burned tips...for the poster above. LOL If you're concerned about root lock up, flush it 3:1 tap water/gallon pot size with the last couple of gallons going through properly pH adjusted. Set it under the lights and leave it alone until it dries out before you start nutes at a very diluted dose. After a flush, you will be solely responsible for the nutrition of the plant since everything got washed out of the soil. Good luck! TWW

    hmm, now that I think of it, it actually does look a lot like light burn, how close is your light to the plants ?
