I did a mid flower flush with water only a few days ago. Also stop using grow big at start of week 5. How would one keep plant greener during flower and after flush or is it just nature of the beast. Did have yellowing on bottom leaves before flush but know its moving to upper leaves. Lost a good amount of fan leaves as well.

Not knowing your setup, after flushing, do you feed? Flushing removes the good stuff.

I know most say to let the soil dry after flushing, but I’ve always followed up with a full strength feed as soon as the bag stops dripping from said flushing. What are your ppm’s at?

Not during flush. I figured since i. Only running water through it. There should be enough nutes left in soild plus i do use earthworm casting in my soil and thought that would also help. My set up is very basic . Over kill but basic. 4x8x6 tent 8 inch vevro exhaust fan mars hydro sp 6500 light and infinity cloudline t4 inline fan for intake.

What PH after feeding?
Do you have pictures before and after a week later?
It takes about 4-5 days to see the results

You need the Grow Big from start to finish Growmie, it’s the needed nitrogen source. Leaves yellowing are a symptom of a lack of nitrogen

I try and maintain 850-1000 PPMs, run off on feed days lets me know what the next cycle will be as in run off over 1200ish is a water day day, 800 or below is a feed day. Follow a drench to drought routine with soil and feed or water to liberal run off using synthetic fertilizer. The liberal run off helps rinse away the salts that can accumulate in the root zone, this also helps keep the medium PH in range

Soil loves the drench to drought. The drought period provides the roots the needed oxygen. Tag me on your update Grow Bro

@OGIncognito thanks for your help grow bro. You can learn a lot from checking ppm. I rarely used my meters in the past. But now i get why thats the first thing most people ask when offering help. Man i was starving my girls. .watered my babies i. Early veg today and ppm was in th 600 range. Soil dry as a brick. Will definitely continue to water to 20 percent run off from now on. Thanks again
