Looking for clarification on the Flush time requir...
Mintystarted grow question 4 years ago
Looking for clarification on the Flush time required for a RDWC grow? I have read this can be as little as 2 days of just plain water but should this also include CalMag if I am RO water? I assume the standard root rot treatment continues? i.e. OxyPlus, HydroGuard, Phytoff?Thanks

Contrary to what happens with soil or coco, where the media keeps some nutrient and needs some time for the plant to consume it. in DWC, once you change the water, there is no more nutes in the growing media, so there is no need for a long flush, 2 or 3 days is enough. There is no need for calmag on those days.

There is no need to flush at all honestly, but if you feel you must, 2 days is fine for hydro. Just pH'd water, nothing else needed, it's just 2 days.

Apricot Oreoz... the Unhealthy RuntDoes anyone have any experience with growing Anesia's Apricot Oreoz seeds? The plant seems to be experiencing a Cal-Mag related nutrient deficiency that the others are not. All plants are being grown under the same conditions. Any suggestions?

Autoflower, deficiency or light stress? End of week 8.Good time of the day. Having following problems with my autoflower (see pictures) which is at the end of week 8. Plant had some light stress before, could that be a consequence of that? Or could that be nutrient deficiency? Looking forward to hearing from you guys!

Roots or some type of mold? Noticed these on the bottom of the fabric potsCan someone shed some light on what this could be ?? I've noticed them on all the pots at the bottom on them, my initial thoughts were could it be the roots ? But then the nutcase in me, started overdrive and thought could it be something more sinister like mould.

Intensity of the smell decreases after wateringI've noticed that after morning watering (I water once a day in the morning) the intensity of the smell decreases. However, at night and early in the morning, when everything dries out, the smell sharply increases. Is this a normal condition?Week 10
