Harvest flush
Blazinjaystarted grow question 4 years ago
Ok I’m sure this is a loaded question but here we go. Straight water in rez for the week or change rez daily ? I’ve gave one plant flora kleen and one with out and see and taste no difference still black ash. I’m noticing now that one plant is starting to yellow doing daily rez

HazeyBobbyanswered grow question 4 years ago
the strategy behind a harvest flush is to essentially stress the plant in its final days for more trichomes production (the plant's defence system) - the key is to give the plant water with as low EC as possible (i.e. plain or RO water). So in your case, keeping the same water in the rez for the week or changing it daily should not have an impact on your harvest. Buds do not leach nutrients of them just because we are providing them with flushing water. Hope that helps - everyone is going to have an opinion on this subject :)

Hi there!
I assume you have an Ec meter?? I think you can measure the ec of the rez daily and if there is lots of dissolved salts (ec has risen a lot) then you should change the res to fresh water again.
I think if the ec is somewhere around ~1.0 ec you should be fine with it!

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.Setup. Strain - Autoflowering

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

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.

We have decalcification machine. Should I add Calmag right from the start? How much? (Autoflower in mostly Biobizz Allmix)We have a decalcification machine (natrium based), so I have low magnesium/calcium. People say my soil is low in cal/mag. Should I add Biobizz Calmag on my first watering?(50% of recommendation for autos?) This one looks already droopy, doesn't it? Think I need to water soon.
