ID:	382365Morning peeps, looking for a bit of help having problems and not to sure what’s causing it. He’s a bit of info about plants. Iam growing 1 dosido and 1 peyota cookie got them in coco 20 litres pots iam giving them coco a&b 25 mill per 10 litres cannazym 20mill and rhizotonic 25 mill. Temps running between 26/28 got 1 600 watt hps on them and I ph between 6 and 6.4. Plants starting to go yellowish and just dosent look well from what iam reading I think it might be magnesium def and the way forward is Epsom salt but not 100% and would like to pick the brains of you fine peeps. I’ll put some pics up and take some more later. Would really appreciate some help as iam struggling.

    Hi mate whats your background ec? If its low it may not have enough trace elements of magnesium/calcium. Ive never run coco before only hydro but its pretty similar, i would use some calmag, as for epson salts i have never used them, hopefully someone with a bit more knowledge will share their input.
    I think your ph could be a bit high too mate usually people lower it in veg between 5.5 and 5.8 and then higher it to 6-6.4 in flower.
    Hope this helps.

    Background ec is your water before you add any nutrients, if this is 1.2 its seriously high.

    Are you getting good run off? Personally, I'd be sticking to a pH of 5.8 to 6.2. The tops of your plants look okay although one seems to be right on the edge of over green. Maybe it's just a light.

    Anyway, when things are looking good on top but not on the bottom you have either a corrected the problem or b you have a mobile nutrient problem. So your mobile nutrients are N P K Mg and Zn, I'd be hesitant to give calcium and magnesium to that one dark green plant unless you have some that has no nitrogen in it. I would recommend dropping your pH, getting a little extra run off for the next couple of waterings and then perhaps some calcium and magnesium for that lighter green plant, if it continues or you could up your feed on that plant after trying a few waterings at around 5.8 pH. If that one dark green one stays the same then it might need a foliar application of Epsom salts.
