Hey mrt notice your havin a bit of trouble with the coco mate heres a few tips dont have to listen mate just though id try an help
1st You wanna put ya tap root up mate, then it curls grows down an the curl straightin up is what pulls the seed out with out the case, cos coco loose puttin it in this way will help, but sayin that they will still germ any direction the seed just doesnt lose energy doin a double curl, i chucked a pic up explainin few pages back.
You want to start addin feed to your seeds in coco once youve got your 1st-2nd set of true leaves(not the round fuckas) at a low rate, cocos got no food allready.
An a little tip with the ph'in mate, i noticed youve allready noticed the rhiz raisers it so can use that if ya to low but be carefull not to rase pmm's to high while doin that an burn the fuckas i do it sometimes but only when i no im safe, another way is to add more tap water till you get back up to what you want this is safer but means everythings gunna be slightly weaker which aint gunna hert nowt. Another tip if your ph'n down small amounts an you keep addin to much, Ph down a 1ltr of water down to like 3-4 then use that to ph down your mix that way you can add a little an it will only go down by a point or 2 even when mixin .5 of a ltr
