yea well i dont use coco so im just repeating what the guys who use coco say, and that is that you should be using coco specific nutrients for best results, i dunno if thats what you using or not?

 

other thing is when you water make sure you have 'runoff' of about 1/4 of the volume you water with , in your case you use 1 litre so you want at least 250mls runoff, otherwise the nutrients quickly buildup nutrient salts within the medium and can burn the leaves, hence the advice is to regularly flush with lots of clear PH adjusted water to flush out any residual nutrient salts which may be present in your medium

 

all da best with 'em

With coco you do need coco specific nutrients.

I find it is best to use less then what is recommended on the label, also a good flush once a week.

Your ph levels are good going in, but may I suggest that you check what your ph and ec coming out of your pots is.

The ec I find is best 1.8 for fully mature plants and for younger ones around about 1.4 or less again for smaller.

If you have been using the proper nutriments for coco there shouldn't be any deficiency.

yeah i'm using canna 100% premium plus coco medium and canna a+b nutes

the run-off has been 1/4 and i have been flushing when it looks like they need it

 

the nutes guideline say's 40ml a+b to 10 ltr water? so that works out at 4ml each per ltr?

 

i think this might be to strong, so have been 1/2 ml per ltr, too see how they handle it, don't want to over do it

my tap water ph was 6.0-6.5 from tap, when i flushed plants run-off was the same, not much difference, when i add nutes to water it was the same too?

 

add some pics
