Each gardener has their expertise in certain areas, and mine lies in aeroponics running a perpetual cycle. I am very inexperienced when it comes to soil, and because I run a perpetual cycle in hydro, I'm also inexperienced when it comes to flushing. Now obviously I've done a few grows in my time where I did flush plants and go through that whole bit, but honestly I NEVER saw or tasted any difference in quality with my plants, so I stopped doing it entirely. This may be due to me using organic nutes, or making sure my plants cure all the way (dunno), but it is what it is, and any of my friends who have smoked my weed with me, tend to agree...
Back to the question: some plants are more susceptible to stresses/deficiencies than others. I've noticed in my own garden, that strains like AK47 tend to yellow a bit towards the end, and even show a cal/mag deficiency, when my other strains are fine. Likewise, my purple arrow and ABC strains yellow out certain leaves along the way. Ice, Maui, and others, stay green until the very day you cut them. So while I'd love to answer your question, the answer would likely be different depending on which strain you plan on growing.
BENJI - that 1st pheno looks REALLY nice for being only 34 days into bloom. I can't wait to see what you do with a scrog setup either m8!
,,,But on a good note the other 2 are doing fine well more than fine they are stinking up, pouring on resin and filling out as each day passes, i have had them on plain PH'ed water since day 41 and i plan on taking them at day 55...
