Slight leaf curl, and yellowing of leaves

Discussion in 'Sick Plants and Problems' started by ScaredyShrooms, Feb 5, 2011.

  1. I am in week 2 of flowering, in a 8x12 indoor spot using 1 600W HPS on 6 plants (OG Larry with one Sky OG that snuck in accidentally). They are currently in a nice organic soil, and are growing nice and bushy. I noticed the other day that the top leaves are lighter than the bottom fan leaves, not spotted just lighter green. Upon closer inspection, I noticed a few leaves out of the entire crop that have slight leaf curl that goes upwards instead of down. Temperature in the room is ranging between 65 and 70, and humidity is ranging from 35-40%. I had a buttload of nutes sitting around, and am currently using up some Canna Flores A&B which I know is for hydro but it's what I had on hand. I also have GH sitting around, and would be willing to switch if it's a better match. When I water, I'm adding 12ml of both A&B per gallon of distilled water. I also have access to reverse osmosis water, but I had the distilled on hand as well and wanted to use it up. I haven't seen any browning on the leaves, and they appear very healthy otherwise and are growing by leaps and bounds.

    Help! I want to head off any problems before they become PROBLEMS.
  2. Two weeks into flower or two weeks into 12/12?
    If the plants are just begging to flower, the leaf twist and slight yellowing could be normal............

  3. 2 weeks into 12/12 and we have some flowering going on. When I checked them out tonight, I found what looked like burn spots on a couple of leaves. They needed water, so I just gave them plain distilled water with a ph of 7.
