    Default Seedlings, watering and nutrients

    Hi guys,

    I need help with watering my seedlings. I literally read everything on google but cannot find exact answer.

    I have 2x White widow, 1xAmnesia haze, 1x Skunk XL.

    They are under 600w HPS.

    I started with 16L pots but I think around 12L of pure Coco natural is in each pot.

    My seedlings are week old and 2 of them started turning a bit yellow so I will start using a+b from canna once I'm back from work today and also got rhizotonic for roots on the way.

    Just wanted to know how, when and how much to water them ? Right now I water them about 0.5L each plant everyday, is this fine?

    With nuts I want to start adding 2ml of a+b and 8ml of rhizotonic per 2L and spread it between 4 plants, what do you think ?

    With coco, always water to run off

    Even if they are 1 week old seedling? is it not going to damage them ? By saying runoff should I have at least 20% or more ?

    Also what about nutrients ?

    Once you start adding nutrients, yes, you want runoff - 10% + is enough

    I normally start feeding at 0.2EC

    I don't have EC pen at the moment, just PH meter.

    Should I start with 0.5ml a+b + 4ml rhizotonic per Litre?

    I will buy EC pen by the end of next week.

    Unfortunately, as the others have said..it's impossible to help here without knowing EC numbers

    I would be looking purchase an EC pen ASAP and since they do look hungry increase the A+B by 1ml (per litre) and hope, since they look to be dying right now anyway..so a last-ditch attempt.

    Looks hungry looking again. Can you get a lights off photo .. I would expect burning at your dosage.

    To give you a clue 1ml of a + b per 5 litre = 0.1 EC in RO
