I have a sativa dom. that's one month into flowering and doing great considering some recent stress (retard ripped off the main cola!). Otherwise, big, fat buds on about a dozen heads lookin' sugary. Question is: What is the ideal PPM? The runoff water shows 308. I have her in soil, in a clay, 20 gallon'ish pot that drains quite well. It's hot as hell here but my meter is auto adjusting for temp.
