I may very well do that haha. My plants didn't stretch much, but I also think the growth is stunted...and I've been using FF Tiger Bloom for a month now. Before that nutes were organic - Alaska Fish Fert(5-1-1) and FF Big Bloom. Do organic nutes leave salt behind? Anyways I've never done a flush and with the syn nutes, tums(cal), epsom salts(mag), variety i've fed - Maybe I should flush? I've also fed 1/2-2/3 the various nute dosage every watering. don't think i've given but 1 plain water feeding.Raising the pot off the ground will do wonders for air flow. Simple plant riser or milk crates work like a charm.
I'm also leaning flush bc...hell I prepped for up to 2x stretch and they only grew 4 inches maybe? Willing to try something extra. Also soil pH is 6.0, seeing further calcium def yellow blotching on fan leaves.
