    Default Is this cal/mag def. ? Or something else.

    Alright folks. I have a auto lemon zkittles day 72 well on in flower and have a bit of an issue recently quite bad now. Have a feeling it’s cal/mag related so ordered some earlier on cos never had problems until now. Here’s a few pics.

    Looks like a calcium deficiency, what medium are you growing in?

    How long do you have left of flower, have you checked the tricomes?

    Also, A1m Hydro on ebay are still posting out as of today. I would normally suggest a foliar spray feed, but as you are flowering, you will need to mix the solution into your system.

    Yeah would say at least another 3 weeks. Day 72 they say 75 but it’s defo goin a lot longer. Will get some in as soon as it’s here. Do I just take my water ec up to .4 with it ?

    I would use it at 0.5ml per litre of your size res, so 50 ml per 100 litres of water. pH swing can lock out cal/mag uptake, has your levels been ok?

    OK, a little jewellers loupe will give you the magnification to see the tricomes, I prefer a couchlock 20-30% amber on chop day, but personal preference will determine your favoured %

    Here is a quick picture, maybe adjust the pH to lean toward the uptake of cal/mag after you have added it to the res and keep a eye on the tips for signs of nutrient burn. Maybe 6.5 for a couple of days and be ready to bring it back down to normal.



    TBF, a hydro guy should chime in soon, I use coco, but it's has the same problems. Also hard water can be a bitch in late flower I've found.

    I always had calcium deficiency until I raised my PH above 6.2.

    One stop Grow Shop are still working and doing a great job.

    What's your Backround ec? If it's really low and ur not adding cal mag then maybe another sign it is that? I havnt worked with low ec water though so I dunno what exactly is needed in a low Backround ec feed.
    Good luck

    Background ec is just under .2 this is my second grow. Never had any problem on first grow. But then every strain is different too. I was reading about it and it says from canna to take your water up to .4 ec then add your feed.

    Would it help any to run it with higher ph for a couple of days 6.5 as the chart says. Or is there next to no cal/mag in the canna a+b and would it be pointless.
