    Default Lower leaves turning yellow??

    Hi,
    So one of my lower leaves is turning yellow and reading on the forum I think it might be a nitrogen deficiency, but I just wanted to get some advice before doing anything.

    Also I'm not sure if one of the top leaves is also starting to discolour.

    List your kit
    What your growing in, lights, temps humidity
    Pretty much anything even smallest detail may be the answer, even if you ritually fart every time you open the tent list it could be methane toxicity

    I am using a 300W Vipar spectra LED light at around 23 inches away.
    Growing in Canna COCO profesional
    Temps at around 26-29 degrees with humidity being about 50-70%
    Growing in a 60x60x120cm tent
    I was using for the first week to begin with Canna A+B nutes at 0.5 of each per litre because I orginally used for the first day 5Ml of each per 5L!!! which was way to much for seedlings, but the last time I watered the plant was the day before yesterday and I just used Rhisotonic at 2ml per litre, because I found out that I shouldn't of really used the nutes straight away and was using to much. I also transplanted the plant from a small 6cm fibre pot to a 3.8L smart pot the day before yesterday as well. When I last watered them I thought I would try something and used bottled water as the PPM was much lower then my tap water, and got the PH to the correct level...so don't know if this may have effected it. I keep the fan running all the time now, but I haven't been using my carbon filter yet, because it brings the humidity and temp down to low.

    Just a bit hot from when you gave to much feed. Nothing to worry about. As long as you corrected the feeds😁

    Thumbs up

    The lowest "seedling" leaves always go like that as the plant uses the nutrients from them to feed first.
    Upper leaves just scorched a tad from ur high feeding.
    It'll be reyt now u've changed it up

    I haven't watered it in 2 days because it doesn't feel like it needs watering, but should I flush it next time or feed it or just use Rhizotonic... I just don't want the whole leave to start turning fully yellow/brown and ruin the plant.

    It wouldnt hurt to flush it i rekon. Get a diary up mate and get a mentor to help you out, that way you get advice from one person it helps.

    I've never grown in Coco so wouldn't wanna misinform you mate. As Hobbit said, get a diary up of ur grow and there'll be more than enough experienced Coco growers along to give u a nudge in the right direction
