Have you grown with this combo of coco and advance nutes before?
How many ppms is this concoction of nutes? I just use the advance
chart but lower the dose the first 2 or 3 weeks and maybe just use
the sensi grow for little plants like your's at a ppm range of 350-500 ppms.
It's your nutes are slighly a little too high ....
I really like advance nutes with the ffof I'll highly recommend it...
Is your ph consistant? If its fluctuating at all, that could be the reason for the deformations and leaves curling up like that.. Im not a coco grower but i think ive read somewhere that the ph/nute issue is extremely touchy with coco
You're adding 5 ml of this and 5 ml of that I would use meter.
I really like the hobbyist level of this chart it's all you need that
other stuff isn't required I know a lot of growers thinks it the
cure all for everything give it some CaMag it be better in the
morning. With fox farm's ocean forest and advance nutes I'm having
the biggest and best grows ever I tried for 3 years
to use the fox farm's nute noting comes close what I getting following
this chart and the sensi bloom and the voodoo juice big bud B-52
and overdrive here's the chart you may have already seen it~ http://www.advancednutrients.com/hydroponics/calc//
What brand of coco you using? I had similar issues and flushed w/ tap water and everyone looked a lot happier. How much runoff do you aim for when watering?
