New Grower When to switch to flowering nutes?

[Mainemedical]

Hey everybody,
I'm about 6 weeks into my first grow of 3 cream caramels that I hoped to get about an oz per under my 600w hps. I was planning on switching over to flowering nutes at this time but due to a ph problem in my soil my plants seemed to be pretty badly stunted. The tallest one is only about 9 inches but they are still growing vertically every day. I know that it would be best for my yield to wait until they stop growing up but I need to harvest as soon as possible. Should I wait til they stop growing vertically to switch to flowering nutes or could I switch now without a much effect on my yield? Any advise is welcomed and appreciated!

Your best switching to flower nutes when vertical growth has stopped around week 6-7 but you could start it now it will reduce your yeild by what i couldnt tell you, but try giving flower nutes with a very small dose of grow still it will work a treat :dance:
