New Grower flush before flowering?

[dingoDark]

I have given them veg nutes 5-6 times,looks like they'r about to give all into flowering in very few days as vertical growth seems to stop. Is it necessary to give them a good flush with plain ph adjusted water now before i start feeding bloom nutes? Medium is plagron light mix,its peatmoss and sphagnum.

Some people do but I've never thought it necessary unless there were other issues that warranted it. Besides removing excess nutes and salts, flushing can also leach out beneficial microbes from the soil. I only like to flush if I see a specific need.

Yes was thinking of the salts,have been feeding 1700 ppm last three times. I will just give one time plainwater and not flushing several gallons,and then start bloom and micro.
