I know u harvest when 75% of hair r red or when the crystles r foggy. i think they r calles caylax or something like that. But how do u tell if ur 2 weeks away from that? I need the info. THX
It's not going to hurt your plant to flush it...you can always add more ferts if you flushed too early, and I've read some people flush multiple times within the flowering stage...
When the first hairs turns red or brown, whatever chron your growing, it is usually when the plant has 2-3 weeks left to flower depending on the strain. That is when i begin my flush, I start then with 80% less fert of what i was using during blooming. So look for those hairs tanning.
One of my buddies flushes after every third feeding this is because he has hard water which he's had problems with before in the past.
Ya that makes sense, I guess I'm spoiled with a RO filter, but with hard water and soil flushes are needed more often, it's true.
