can someone diagnose this nutrient problem?
    #584185 - 09/07/11 03:28 AM (5 years, 2 months ago)

this is a shot of one of my jack colas
it seems to be only the jack's doing this. out of 4 strains...
the jack also take up water slower than any of the other strains..
ill try and take more pictures when i have the chance
this photo was taken in the couple seconds before my lights went from on to orange :grin:

you can see a slight discoloration, a yellowing of the leaf.(second picture more so)
this is top canopy growth, so its not typical
some of my bottom leaves have been doing this, eventually drying and falling off

but i just figured thats natural as it happens more commonly with my outdoor plants

my soils/amendments 100% organic
nutrient also organic.
i dont think i fertilize as heavy as most ppl, but i dont flush as often as most ppl.

i do not know my soil pH. but i just watered with a weak nutrient solution (pH 6.7, and the runoff was pH 6.5)
previous watering was a straight h2o FLUSH
this most recent watering had some nitrogen in it also, to try an relieve the signs of nutrient stress

other than the diagnosis
could you guys/gals tell me:
- when it comes to mid/late flowering, how much do you step up potash and phos? and which more than the other, and when?
- do you apply nitrogen at all during flower?(im used to composts and organic matter to supply the plant everything thru its entire lifespan)
- do you apply molasses? when? any specific brand?
- do these plants look ok? healthy? for 3 weeks 12/12
no swollen calyxes yet, but juicy healthy pistils :grin:

As far as i know you shouldn't use much nitrogen at all to let your plants use up what is left in the soil..
