  2. they have a nitrogen defficency my friend, give them some N nutes, the only time this would be natural and welcomed is late in flowering when the plant uses up all it's nutes..........Peace out............Sid
  3. they are showing a magnseium deficiency

    nitrogen deficiency leaves turn yellow along withthe veins
    with a magnseium deficiency thel eaves turn yellow but the veins remain green untill it moves farther in the leaves

    you need some magnseium
    epsom salts dolomite lime or something with magnseium will fix that up

    what nutrients are you using now howm uch and how often? if your using any that is...
