Flush duration in DWC
Cremostarted grow question 4 years ago
Okay, so here's the deal. A lot of people say that flushing should take a week or two. BUT flushing DWC could take only as little as 2 days. Is that true or does the medium really not matter at all? THX :)

I've gone 0 days to a week for my flush and really don't notice much of a difference. Some plants I've given a longer flush don't burn as white as others with a shorter flush.
I found it is more important to lower the feed (EC .6/7 and lower) the last 10 days or so.
I like to do 2-4 days for my flush. The plants I have in flower now I am going to do 2 res changes of new water and see if that makes a difference.
good luck.

Medium matters
Soil is slowest if flushing mineral salts simply due to being able to move less water through it. A week to 2 common.
Coco is a bit faster being hydro prob 1/2 the time for soil, Four to seven days.
DWC yeah 2 days should do it
Use of a flushing agent will speed things up

Questions about wateringI 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.

Should I wait to flip?Since I just transplanted and amended my soil using gaia green amendments and geared them towards veg. I know the general rule is to allow 2 weeks for them organic amendments to break down, will that deter me from flipping to flower next week or should I wait if so how long?

Am I on a harvest window?Am i on a harvest window?
77 days old autoflower, up to this point is personal taste or still there ways to go?
I majorly see milky and a few ambers trichomes, correct?
Those white pistils are due to the foxtailing, so is not a good metric.

Help: potential over fertilisation or over waterningI used Biobizz bio grow, 2ml/L and sprayed them more than usual. The tip of the leaves is getting yellow. 2 plants have the leaves pointing down and seem more textured and tick. The other 2 (the biggest) seem better, but the yellowing of the leaves is more evident.

F44: dozens of gnats stucked on buds & sugar leavesHey,
I noticed dozens of gnats stucked on sugar leaves and buds trichomes/resin... I tried to pick them by hand but there are too many.
I saw articles about bud washing which seems to be a good thing except for higher mold risk.
Would it be the only way to smoke bug free weed?
