got some of this tropic mix from the shop, its the shops take on canna terra pro plus but this has nutrient in it, pre fertilised if you like ! 

first time i had a go at it and tbh I'm not a fan, got a white furry like mould on top of the pots, (top of medium) and i noticed some discolour on some leaves, i have no idea what it is but i do reckon its something to do with the medium, i did freeze it first like i do with all terra as to de-bug it maybe this has had an effect seeing as this contains nutrient, 

 

anyway enough rambling, heres a pic

It doesnt look to bad mate but not perfect.
Have you checked the ph?

The mouldy white stuff is either white mould or could be the excess salts within the medium showing up.

If the ph is where it should be then its able to feed but cant so its either locked out due to the mouldy stuff in the medium and roots or its simply starting to run out of the nutrients in the medium.

adding great white shark or some other type of mycorra bacteria or benifical bennies will help that a lot.
but first. Check ph. If ph is out then flush it clean an feed. If that doesnt help then treat roots an medium with gws etc.

Keep us updated mate

 a foliar feed of high ec veg nutes twice a day for 2-3 days and check your ph meter calibration is what i would suggest,good luck

I don`t think its anything worth worrying about too much, i remember seeing it last week in one of your pictures and tbh it doesnt look any worse.

I'd say more or less the same as the other answers here; probably a ph issue, some of the seedlings I have going just now have the same kind of discolouration, checked my water ph, was 7.7, a touch of ph down to get it to around 6.5 and the new growth isn't showing it, just nice and green as it should be

cheers lads ! 

@ mellowed its crazy when i think about it, i have some ecothrive charge, (soil/coco conditioner full of bennies) and some mikos root inoculant in the cupboard totally forgot about em, the charge stuff is good gear imho ! suppose i could top dress some 

 

need to stop dabbin i do !

I would mate. just to balance it out a bit. Bennies wont do an harm at all.

its the only one to persist with this problem as the lemons are flying and so are the other jilly's,

i think it could of been ph lockout as i checked the water i was giving them and it read 7.3ph, i adjusted down to 5.8 drenched em and it seems to have sorted em out, apart from the one in the pic, it is a reg so i don't know if to just bin it off, got another so fingers crossed not just for a female but for a good pheno, got em on a 0.6ec feed now too !

7.3 is very OK for pre-fertilized soil. 5.8 is way too low. It seems you are having a calcium - magnesium deficiency.

@ Fonzee its not soil as such, coco and peat, and shite lol won't be using that again ! got em in the old canna coco pro now and flying m8 checkout the coconuts thread, i just put some pics up of em now !
