I dont have a ppm meter but sounds about the same as my problem. The purpling is a Mag def caused by high ppms. Ive been raising my ph to 6.3 and watering that in to get it back in check. I didnt flush this i just adjusted the ph and it seems to be working. 2000 ppms might need to be flushed out.

Hey Bud, I hate contradicting people but purpled petioles are not indicative of Mg-, they're indicative of P-. Mg- shows first as interveinal chlorosis of the lower leaves, and progresses to necrotic margins, then full leaf death & drop. P- starts as reddened or purpled petioles, then progresses to the leaves taking on a 'too dark' green color, then random browning & yellowing, then full necrosis and leaf drop. :)

A correction needs to be made to this chart. It has Ca listed under mobile nutrients. Ca is immobile, not mobile.

Root Aphids, god I hope not. I have to check, but my problem looks more like a K def. Should I just do the usual and flush with low ppm solution, or could I get away with 2 gallons of ph'd tap and 3 gallons of low ppm solution?

I'm not the pro, but everyone told me never to flush with plain, use diluted nutes.

you say your watering by hand? are you giving nutes every time?

i think im going to nail this one on the head... :D

im gonna guess overwatering and other things...a combo...here is what i mean...

if i take a clone and plant it to a 7 gal pot, the plant is way too small and will take a long time to grow roots throughout the pot, now if you water this 7 gal pot FULLY, the plant will never grow roots because the media will always be saturated...now if each time you water the top feels dry for 2-3 inches, but the bottom fels kinda like it still has weight, and you keep feeding with a full watering, you are building up nutes in the bottom of the pot and the plants roots never get there to eat them and drink up the water...by time it does(2-3 weeks into flower like you say) the salt concentration at the bottom is so high the plant goes into lockout mode....

i must also mention that i do not use any "zymes" because i find it did nothing but break down my growing media causing ph to lower (promix)...



that being said, i grow in promix and water with ferts every watering, veg @ 400-700, and flower 700-900ppm depending strain...i dont use much, a base nute, cal/mag, and a bloom booster(0-51-32)


now with all that being said, to fix your problem im going to suggest to water less when you do water, i never water till runoff...basicly when i plant my clones for vegging, i water enough to wet about half the container, then the moisture spreads out, to evenly MOIST-not wet or drench the rest of the media, creating a moist environment for roots to thrive, if its too wet roots wont grow, feeding them more wont help....basicly i start by watering 20 seconds each, then when they need watered every 2 days, i water 30 seconds each, then when they need watered every 2 days i water 40 seconds each, this allows for roots to FILL the container, ive noticed in the past when i would do "DRENCHES" like you are doing, roots would not fill the pot, they would grow straight down to the bottom and circle the bottom but none would be throughout the rest of the pot...


anyways its late and im high and rambling on...lol..anyways good luck
