Yellow leaf tips very early

Discussion in 'First Time Marijuana Growers' started by Heuristic, Jan 21, 2010.

  1. Soil - Fox Farms Original
    Type of light? 2 - 27w CFL Cool White
    "Atmosphere" Conditions - 70º, dry, small constant fan
    Waterings - Tap water
    PH Range N/A
    Nutrients/Supplements - None

    I have 8 - 2 week olds and the leaf tips are turning yellow and turning up. They started this while still in small trays filled with vermiculite in a tray with about 1/4" of standing water. The roots quickly grew out of the trays into the standing water, and were like that for a few days before I cut the bottoms out of the trays and put them in 2 gallon grow bags with Fox Farms.

    My assumption is that they received too much water early, but I'm not sure.

    Should I keep watering to a minumum and see what happens? Any other ideas?
  2. Yellow leaf tips sounds like a fert burn to me.

    Any chance we can get some pics?

    Good luck.
  3. Here's a pic. They don't seem to be getting any worse now that they're in soil. Perhaps it was chlorine burn from having the roots submerged in the tray for a few days with tap water in it?

    I think I'm going distilled from here on out.

  4. Probably chlorine burn but you also need some more lighting to help them heal faster. And get the daylight, use the cool white for flowering.
  5. Picked up 4 27w Daylight CFL's at lunch and two more reflectors. I now have all 4 going on 8 youngin's. Hope to see a bit more growth in the coming days, they've been moving pretty slow so far...... :cool:
