I’m using coco/perlite. In wk 2 of flower. I was thinking about flushing the grow pots out with RO water -flooding the pots to drain/flush out any build up. Then re-flooding with fresh nutrient mix. Is there anything wrong with doing so? Thank yo
there's a few products that will help to do that exactly, like florakleen. I do it from time to time without any problems.
If you do flush I recommend using ph’d water. You can use straight RO water but my theory is that the ph imbalance stunts the root hair ion exchange sites. I have flushed with non ph adjust water and ph adjusted water. Both worked but for peace of mind I just use ph adjusted water to flush.
