    Default Please help diagnose a few issues

    Hi again, back here again I think I worry too much lol. I've noticed my leaves are starting to have a slight yellow tinge to them all over and worse I've found a few small brown spots on 1 on the plants. See what you guys think

    Soil or hydro or coco: coco/perlite 70/30

    Strain: Northern Lights Feminised

    Photo or Auto: Photo

    plant age: 23 days

    pot size: 11L

    has it been repotted? and when?: No

    soil type: Coco/perlite 70/30

    nutes or additives used and how often for soil:

    Air temps (max min):21/28

    Res temps (max min):

    humidity: 50-60%

    lighting type and wattage (hps, led, cfl): 600w duel spectrum HPS

    Light schedule: 18/6

    ph level: 5.8

    EC (hydro and coco only): 1.1

    Background EC: 0.2/0.3

    feed schedule and nutes (for hydro and coco): 2ml per litre rhizotonic - 7.5ml per 5l canna A+B - Calmag used as foliar spray

    I added 1ml of calmag per 5l of feed yesturday as I suspected it maybe a mag issue, I also topped them about 5 days ago. Also they seem to be quite short and bushy the biggest one is 6" tall now don't know if that's just a strain thing





    Thanks for any help in advance!

    yea mate every day in coco, thing is you started them in big pots?
    i would double check the calibration again as it shud be done at least once week. with every day feeding they should green up mate.
    you getting any run off?

    also get a bag of epsom salts, stick a table spoon in to 4.5litres of warm water mix it, then remove 1litre of this solution with a 1litre jug and pour remaining solution of the bucket down the sink.

    now with your 1litre jug of epsom water add in 3- 4 ml calmag. give good mix and spray them tops an underneath, do this with the lights raised as high as possible and with the lights on, this shoudl also help green them back up

    They were acting like I had overwatered them before quite droopy. I read that you feed everytime its dry a knuckle down into the coco. Read a quite good guide on growweedeasy.com

    its quite confusing allot of contradicting information, Really not sure what to do then with regards to watering. maybe every 2 days instead of 3?

    devilscrack is there a suppliment i should be adding? i was under the impression that Canna A+B should be enough as long as it's at right EC?
