    Default What's going on here?

    Hello talkers
    Gonna have to post in here for a bit of help.
    Got some yellowing of leaves up on the canopy. Still dark green on new growth and under the canopy as u can see from the pics. Some leaves have a few shades of green/yellow from the edges into the middle gets darker some are just much paler. Not sure what they are lacking or if it's just normal for its life cycle. They have never had any cal/mag foiler and don't want to do that now I'm in full swing of flower. Info below cheers
    Soil is b&q verve with added perlite

    How close the lights Wags?

    I'm seeing mag deficiency in some leaves. A splash of 0.5ml / L magnecal to the roots will sort that out

    Hey dude. Lights are 13inches away from tallest cola. I've got some plant magic magne-cal. Read against feeding that in soil tho? Or is it OK in small doses?

    Answered below/above but yeah a tiny bit is fine in my limited experience. My Coco plants get 0.2ml every single feed, and it's not enough tbh with QBs.

    Bright light brings it on quicker. I bet your leaves in the shade from the top leaves are much greener.

    Back off the lights a bit until the green returns but they won't get that much greener now

    is ok in very small doses, mag/cal is full concentrate and they need very very little to correct,
    don't go by the bottle dosage please,

    when did the burnt tips show up? the same time they started to pale or before??

    this question ur not gonna wanna read but, do you know what the ph of your feed/water is compaired to runoff?
    hopefully it's just a mg deficiency like gardro said,

    did the yellowing start in the middle of the plant then spread to the newer growth?? that's a good indicator it's just mg/cal deficiency

    My first thought was light being too close. Following to see what the result is anyhow. On above topic... When I had a mag deficiency I used some Epsom salts and sprayed over the plant. Preferred to adding more nutes into feed :-)
