DWC feeding chart detailed


#1

Hi, I am just about to start the a new batch of seeds. My question is, is there a specific feeding chart from start to end? I will be using rockwool as main medium, dwc, 18 liter bucket and most importantly General Hydroponics 2 stage (micro, grow, bloom). One other thing I will be using RO water which is currently at 50ppm, should I add calmag to every water change, or the gh has all the calcium and magnesium the plants need?

Thanks

You will need to add cal-mag as well… I would also suggest a silicate to add as well …
You said rockwhool is your medium …
Is this a flood and drain or a dwc or rdwc…?
Rockwhool isn’t the best for dwc or rdwc…
More info needed…
And yes there is a chart that can help you determine when to feed and how much based on age of plant… need more info…?

Yes I would need more info as you did not answer anything xD recirculating dw.

I want an actual one not the one on there site as it is way too strong for seedlings

I run rdwc systems and I dont go by any chart…
I go by the age of the plant and what stage of growth I’m in…
You should look into hydrguard and orca… they will help tremendously…
I need more info on your end to be able to give best advice… maybe even a couple of pics of your system and set up…
Using rockwhool is going to be a lil bitt of a pain do to overwatering and damping off issues…
Need to know more about what your doing…
I dont use any media… I just run a neoprene holder and a empty pot for support and water and nutrients… nothing else… :grin:

I use a simple formula…
2 mill bloom , 4 mill micro , 6 mill grow… in veg

Transition , I use 4 mill bloom , 4 mill grow. 4 mill micro…

Mid flower to late flower … 6 mill bloom , 4mill micro , 2 mill grow…

Always add 3 mill call-mag until 5 weeks till estimated finish…if using ro water with a ppm of less then 25 ppm…

Always 2 mill hydrogard and orca … up till 4 weeks of finish…

Depending on silica supplement you use , 1 to 2 mill until 6 weeks from finish…

Diamond nectar… 2 mill until 4 weeks till finish…

All measurements are to 1 gallon of good ph water of 5.5 and no more then 25 ppm to start with… :grin:

Change at least every 14 days depending on size of system… (ie) how much water it holds…

5 gallon buckets… Need to change out every 7 days with new…

Haha talk about answers. I feel educated and i dont even use rdwc :joy::joy:


#7

I should also add … that I use crystal burst and snow storm ultra … mid to late flower… crystal burst as soon as you see flowers and one more time 2 weeks later…
Snow storm ultra till 1 week till harvest…
On a 14 day schedule…
2 mill to a gallon for each with everything else mentioned above… :wink:

Sounds complicated , but it isn’t… :grin:
