12/12 food

hey guys

when i switch the 12/12 do i switch to the flower food straight away?i,m using canna and does anyone know what ppm i should set it at,ive done a couple of grows with cell max and always had problems with burnt leaves when going by the bottle instructions,i was wondering what ppm you start at week 1 the accordingly up until harvest,a step by step guide would be awsome if you know of one or if anyone has got an ISBN number for a decent book on hydro (prefrebaly nft)with ec/ppm tables, weekly guides an easily broke down material,i'm not thick or anything but my 1st grows were over two years ago and i'm back to basics,read jorge cervantes book but hydro section week to say the least, currently growing BF blue cheese..........

regards smarts :spliff:

Leave em on grow nutes for 2 weeks after you switch to 12/12.

Depends on the size of ya plants and how much they're feeding. I would go for an EC of 1.6 and see how ya go. If ya EC falls, put it up to 1.8.

Have a look at a grow diary for your strain.

Can ya post any pics?
