Northern Lights

start feeding them 1/4 of the dose, then gradually increase over three weeks, i.e. do 1/2 dose, then 3/4, then 1/1. if you do it gradually you have less chance of upsetting them. some people feed once a week with plain water in-between and some feed more dilute nutes every watering.

NL can take a lot of nutes but don't over do it. keep a close eye on fan leaves as they usually indicate first if you're over/under ferting.

the 100w cfl is fine for veg, just make sure the light is only an inch or two above the plants.

thanks for the advice emmpey, much appreciated :)
