Couldnt get any cal/mag so i bought some epsom salts, how long does it take for it to work. I used the salts with my normal feeding, shall also use it as a foliar spray or just wait. Should i use this with my feed again or is this enough, the def seems to be getting worse so any info will be much apreicaited. Nice1

I don't know anything about using epsom salts, But i use Molasses when my plants go mag def. but most all purpose ferts have mg in them. check it out. It also depends on wether your deffiency is caused from a nutrient lock out, or from that element being exhausted in your medium.

as mentioned, it looks like a mag def. now you have to figure out why. you're either experiencing a deficiency, or one brought on by ph lockout.

If you are sure, then buy some molasses, and use 1 table spoon level per 2L bottle, and water with that. Molasses has lots of usable Mg. Makes the buds taste great too.

sorry dude, i don't do metric. you don't want huge temp. fluctuations between lights on/off. when i lived in oregon, i had an oscillating heater on at lights off to keep temps. up. (make sure it's a ceramic heater, and not one that lights up when on.) also make sure the plant containers aren't on something like concrete, which can get very cold. don't want to freeze your roots...
