Can Anyone Advise

[rachsymes]

I have 9 plants under a 600 light which I have just turned over to 12/12 two days ago... I turned them up to 660 over boost but then I noticed some of the leaves turning yellow so I have turned it back to 600... does anybody have any idea what is wrong with them any advice would be appreciated thanks all.

Its not the light, they need food

Yellowing is not because of the light. Bump up on the nutes..as previously suggested.

Nobody can correctly answer this for you without knowing the rest of the particulars such as, what is the medium they are planted in now ? What have you been giving them up to this point?

 

[rachsymes]

the medium is canna coco natural I always use this and have never had a problem before and I feed them canna a + b 40ml per 10 litre and again I have always used this and never had a problem

not everyone needs it....depends on your water source and medium

I believe the use of cal-mag is much more important when growing in coco
