Grow QuestionsTransitional flush and its effect on beneficial colonies.

Transitional flush and its effect on beneficial colonies.

DWCbadassquestionmarkstarted grow question 5 years ago

If one is growing in Coco, and using bennies (Mammoth P, Great White), would a flush during transition be detrimental to those colonies, or would it be an irrelevant variable? (Sorry, I have 2 questions just sitting here, might as well use them.)

I always flush a few extra gallons a week before flower. Helps get rid of all the extra salt. I also check my ppm runoff every water. If my ppms get to high I'll add a little more water than usual. Every water should have some runoff.

Hello,I grow in RDWC and why do you want to flush? You do not need to flush in DWC except for when its time is up or Harvest time. But just from veg to flower not needed You will loose those colonies if you do flush.😊

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)Maturity in day 49 flower from 60-65 (according to breeder) I'm not sure about the degree of ripeness. I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ? What should I do Thank you

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200. I guess EC gets diluted (biggest part of coco coir is new). Should I increase EC of the feeding water? I see slower growth but it may as well be due to stress of repotting.

Questions about watering I created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.
