We need more info, but based on the pictures it could be a ph issue. What kind of soil are you using? Is it draining well?

 

[Muddy]

Could be a nitrogen deficiency or the start of a cal/mag deficiency or a lockout caused by the pH being off. What is your soil mix and it's pH?

cheerz 4 the response kp,my soil mix drains realy well,its westlands john innes 2,with perlite,vermiculite,as iv only fed them once wen they was 3 weeks then last week with biobizz bloom n topmax i only gave them 1ml to litre,iv got a ph meter one of those electronic ones it cost £30 but it needs calabrateing and as im a newb iaint got a clue how to use 1,lol...

It looks like your soil is a mix of peat moss, grit and compost, but I couldn't find anything more on what type of grit or compost. It also says it has enough nutrients for about 4 weeks. I would say at this point it looks like a nitrogen deficiency so I'd feed them some more. Sooner or later you're going to need to figure out how to use that pH meter. The sooner, the better.

thanks muddy,thers also little black spots on 1 or two of the leaves,kinda looks like hot rock burns like when your smoking hashish,so maybe a bit of nute burn maybe?? also i got the biobizz 3 pack bloom,grow,and topmax but the grow nutrient is quite thick and gloopy but the other 2 bottles are fine is it meant to be like that?? and with the ph meter it says i have to calibrate it first any help woul be cool as iv spent quite a bit of $$££$$£ on this first grow and dont want everything dieing,wish there was a start to finish guide lol,peace out

 

[Hopper]

Looks like N -def to me. Especialy as you only fed once, nice going anyhow

 

[Muddy]

I doubt it's nute burn if you've got a N deficiency. Sorry, I've never used those nutes so don't know if the thickness is normal or not. You will need calibration solution to calibrate your meter. If it didn't come with any you'll need to buy some. The instructions that came with the meter should outline the procedure for you.
