    Am only feeding so high as I was advised too, the yellowing started around 2 weeks ago so started upping from 2ml per L to 3ml, 4ml..

    Not making a difference though. But not showing signs of over feeding or nute burn so not doing harm I guess.

    Okay, sounds like you don't have an EC meter. That's what you need to find out some information about your background water.

    Have you been getting good runoff every time you water your plant? If not, if you're just putting in enough water to get the pot wet then you would almost certainly have some lockout.

    Then a flush with the light feeding afterwards would be in order.

    IIRC she's an organic soil grower, mate. I am too, and never have used an EC meter. I don't think they even show up on an EC meter to be honest. I am sure I read somewhere that they don't.

    you only at 8 weeks, up the grow to 2ml of Veg for a couple of feeds. Mine were the same, I upped the grow and it's sorted. Remember the yellowing won't clear up on the existing leaves but it will stop it spreading to the sugar leaves. Start flushing around 2 weeks before harvest.

    Here's 1 of mine, around 10 days after upping the N and at 63 days now

    Makes sense, I'm running some Remo nutes in Coco that's organic. First time I used it I was way under feeding my plants cuz the EC is so high with that nutrient line.

    if youre at max dose of feed and she still looks underfed it could be high RH ,being unable to release through leaves will stop her pulling up more feed via roots,cos "she full".

    are you getting the dry cycle as normal?,or is she taking longer to achieve dry pot status?

    sorry for funny wording,baked n buzzing.

    good point mate. I also had high RH (60) for a bit and watering was down to every 4 days. I pulled all the yellow leaves and any excess and RH back down to 38 and watering every 2-3 days now.
