Sorry I never said its coco canna cocoSo your soil/coco has nutrients in it and you are feeding on top of that?
What is that soil? Is it coco with perlite added?
Iv tried starting cuttings same size at 1.0 e.d in past i get more problems, the bags says 1.0 but don't work for me, I checked today roos are looking good just bit yellowish, I'll post some pics nowCoco mediums need regular feeding. Your coco brick is no different. Feed your plants at 1 EC, 5.8ph and see how they respond. Feed, feed, water, repeat
Ok might try some calmag with this grow see how it goes at 150-200ppm.Yea for as big as those plants are whether in coco or normal dirt .2 EC is WAY too low, that why they are turning almost a yellow green on you, also the brown rust colored patches on the leaves from the older pics is definitely Calcium deficiency.
With any medium whether it be soil, coco, or peat based, you want your run off to be right around 200-400ppms OVER what you feed in, .2 EC depending on the PPM meter you are using usually converts to 100ppms, that is no where near enough food for them, because that 100ppm (.2EC) runoff is most likely just extra bullshit that arent actually going to uptake like Micro Nutrient, you can tell from the plant and the EC run off you stated that the plant has no NPKs left to feed on.
Seeing that I assume you have a ppm meter, feed your plants around 400-600ppms at the stage they're at! Make sure you add Cal Mag too, add Cal Mag first, do about 150-200ppm of Cal Mag, then add all the rest of your nutrients and get it to around 600ppms and then PH to 6.0-6.2, then feed your plants! Keep that up and they will go back to beautifully lush and dark green, the leaves that have the rust patches on the are dead, they wont come back, so just cut them off. But it will stop the spread of those rust colored patches from spreading any further!
Thanks just what i wanted to hear that the old big plants was calmag, as I can't think of what else it could really be.Yea for as big as those plants are whether in coco or normal dirt .2 EC is WAY too low, that why they are turning almost a yellow green on you, also the brown rust colored patches on the leaves from the older pics is definitely Calcium deficiency.

Thanks,Make sure you add Cal Mag too, add Cal Mag first!!!
I am new to coco not new to empty mediums sounds like you need cal mag.
In my hydroton and coco setup I run with 5ml per a gallon of ro water @ 10ppm nets me a 260ppm / 0.5ec
It sounds like you may have a 700 scale ppm meter so be careful when using others ppm readings.
Ok might try some calmag with this grow see how it goes at 150-200ppm.
I'm already feeding 0.8-1.0 what I mean is the coco has a e.c of 0.2 out the bag before I add my feed at 0.8 even tried 1.0
I binned them big ones I didn't have the head to mess about already wasted 2 weeks messing with them.Oh ok... My mistake I thought you meant your run off was .2ec
I was like thats way too low... But if your hitting them up with .8-1.0ec that amazes me that they are yellowing out like that! But if you get any cal mag that has Nitrogen in it then that will definitely help.
Anytime the leaves turn yellow as long as you correct the issue then they will green right back up, but when you get Calcium deficiency that progresses to a large portion of the leaf, that's actual necrosis (leaves are actually dying) so the rust patches will never go back to being a healthy leaf, but if it is only a subtle affect of calcium deficiency then I wouldnt worry too much. But I would definitely cut off the leaves that are bad, it will force your plant to put out new growth!
Thanks some nice infoI read PPMs in the 500ppm scale for my Bluelab PPM meter, some meters run differently but most are very similar, but most people read their ppms in the 500scale, a lot of pens read differently for EC, most go based on .1ec=50ppm, but some other pens and meters read .1ec=100ppms, so just be careful using EC when on this site. Sounds like you have a meter very similar to mine!
But that CAL MAG is perfect,
Just watch the PH though when you add it, most cal mag is calcium nitrate and magnesium nitrate which are PH balanced salts, but calcium oxide and Magnesium Oxide are usually basic/alkaline in nature, so it may possibly bump up your PH! I could be wrong but just keep track of your PH
