    The top 3 inch of coco was dry so I have just given them a little drink because of the size of the pots compared to the plants I don’t want to over water

    You need to know how salty your tap water is.

    You then are adding salt / feed ( your AB ) so you need to know the final saltiness of your feed.

    Do you know about pH?

    You need an EC pen to go further if you are learning.

    EC and pH is everything.

    Have you calibtated your pH pen?

    The range in coco must be 5.8-6.3

    I’ve ordered a EC pen ..
    I used the same kit for testing the water in my tropical fish tank the reading will be accurate

    I actually grew for 7 years but had to pack it in so I’m getting back into it. It’s Been a while.

    I just never had this before that I can recall

    We can get you growing the very best bud dude. Give us a shout when you know your EC and pH otherwise we are stabbing in the dark

    Ok,

    pH pen
    EC pen
    Target pH is 5.8 or there abouts
    EC feed total should never really go above 0.8-1.2 and that's strong.

    Let's say you have a tap water EC of 0.6 (hardware, great for seedlings unless excess of lime and chalk etc) and your feed EC of 0.8 that's a total ec of 1.4 which is fine but if your BG EC is 1 and you feed 1.2 total that's too low. But 2 may be too much.


    Your leaf issue is nite lockout it's not taking up the full NPK of the canna nutes.
    Dial your pH in and watch new and old growth for changes
    Get yourself an ec pen and keep feed EC under 1 for now.

    Bit too early for pK you're not in flower and the P will just nuke your plants especially if you're not measuring the feed properly

    Completely get that mate.
    Thank you for both for your time. I think I’ve ruled out light burn or infestation now.
