Also I showed them to the people in my local grow shop and they reckon it could be a cal- mag problem bit to sure what to do:/

[SukonmiSkunk 97]

yeah cal-mag is caused from ph too low.. you want to aim for around 6.3

anything under 6.0 is too low

this will show you the various nutrients and their PH range.. its the same for soil or hydro

Thank you so much for your help mate. There in the first week of flowering at the moment if I adjust the ph will they recover and If so how long do you think it would take

[SukonmiSkunk 97]

yeah just raise the PH a little.. aim for 6.3 if its a little below or above them it wont matter.. but keep it above 6.0

they dont look bad.. they will start looking a bit better in a few days

Yeah just fed them now with the ph at 6.2 I can not thank you enough been so worried about them thanks once again.
