Hello and welcome to the forum Lowrollerbean, sorry to read you're having issues.

We really do need to see some pics, but the forum has an image posting requirement of at least 10 posts, which is very simple to achieve without spamming as we have lots of interesting topics/threads to get stuck into

Once you hit the 10 posts (or a friendly admin decides to bump you up), then you can share some pics with us and get more help from the members.

Don't know anything about coco but yellowing leaves usually means hunger but really do need the pics to help you out here mukka so get your post count up to 10 and lets try and get you sorted, all the best bro' G'.

Thanks for the help, turns out my ph pen wasn't calibrated and ppm meter was out slightly, so increased food now waiting a day or two for the difference....or the burn!!

So with your ph pen being out could you have put the ph in the pot out? Causing lock out. May be worth looking in to run off numbers lad. 1 ml a and b per litre gives me an ec of around .6 or 0.8 somewhere between but thats with my bg of 0.4 so depending on size of plant it could just be hunger, photos due!!

[Lowrollerbean]

Yes I was thinking this too, my ph run off was 6.2, water/food going in was 5.8, so after discovering my pen was out .5 that in turn means my run off was really at 6.7, pot size 8ltr plant size exactly 30inch today

[SmobyToker#1]

take some photos and do a run off test of the ph and ec.

I'll try upload picture around 7:30, if all goes to plan
