vancitybuzz started grow question 5 years ago
Which NPK ratios have you tried, and which ones work the best for different stages? I' on day 1 of week 2 of flower and have just done a res change with an NPK of 1-2-3 in 10gal of water: Micro-25ml, Grow-75ml, Bloom-50ml. Do you agree with this, why or why not?

Greetings. My friend I also grow o hydro (DWC) and also use GHE. I follow GHE feeding charts wich you can find on their web page... like bigdaddyk said don't overthink. I'm going to tell you how I've bee doing my feeding: so Im at this moment at the transition. I switch to 12/12 last saturday and according to GHE's feeding chart I use same amount of micro grow and bloom (10ml/gallon). Half that amount

(5ml/gallon). Now. I use to change the reservoir one more time after a couple of weeks with those feeding parameters to the bloom feeding needs.. I want to tell you that I have learned that when you use the GHE's feeding charts i cut quantities in half.. so if the chart says to add 20 ml of flora grow per gallon I just add 10ml. If you don't have a ppm pen I strongly advise you to get one..I have also learned that if the chart tells you that your water should have a ppm between 950 and 1300ppm os always better to be on the lower sid, meaning that you should try to keep your water ppm at 900 and 1200ppm.. I follow that rule that I learned by my self and I can proudly say that my plants don't suffer from deficiencies or nutes burns.. also I use to pin dead the ph at certain level between 5.5 and 6.5 lets say I pinned it at 6 and didn't let it move from that level. That my friend is also going to create deficiencies. Only correct your ph once it went under or above 5.5-6.5 let your ph fluctuate between the levels to make sure all nutrients are absorb by your girls... hope this was helpful. Good luck and happy growing!!!

Don't overthink , use basic nutrients and add some cal mag , less is better than too much in DWC you can easily use 1/2 manufacturers recommended amounts , plants need water , oxyegen and light , the last one bring the most important .:+1:

I'm agreeing with green on this, more difficult without the pictures for sure.. to know and see where you're at.

Nutrient requirements are minimal. Less is most definitely more. Most growers favour a high N feed. An NPK ratio of 3:1:1 during the growth phase. Of course, some strains will respond better with some slight tweaking.

It’s not all about nitrogen, but N levels should always be higher than phosphorus and potassium until bloom. Nitrogen-rich feeds are not required for soil growers as most high-quality cannabis soils contain enough fertiliser for the first 3-4 weeks. Just add water and keep an eye out for nutrient lockouts. Alternatively, Vertafort grow tablets can slow release nutes during vegetative growth. (Which I have, and they work quiet well).
Plants transition into flower, nutrient requirements swing in the opposite direction. That means switching to bloom base nutrients and adjusting the NPK ratio. A effective NPK formula is 1-3-2 for early to mid-bloom, followed by 0-3-3 for late bloom. Add a final flush of pure water and/or light flushing solution during the final week for flavour. Then, it’s time to harvest. P & K dictate the quantity and size of bud, respectively.

Tapering off N levels while simultaneously increasing P & K is the primary grower objective. Too much nitrogen late in bloom spoils the sinsemilla. Buds will taste harsh and just won’t smoke as smoothly as a thoroughly-flushed crop. Leave out the N altogether for the final 20-30 days.

Every cannabis strain has its own nuances. This is true when it comes to nutrients and feeding too. Regardless of whether you intend to use organic or chemical fertilisers, you must incrementally increase doses. You simply cannot launch right into full-strength feeds from the get go. Again, Vertafort slow release organic bloom tablets are a viable alternative as they time-release nutes throughout flowering. This is just advice and you're free to do as you wish, but in MY opinion this is what generally works. Good luck

Without all the info thats hard. I'm sorry you cant get your pics and info uploaded.
With the flora series its recommended at the preflowers to do 8ml/L of grow, 1.6 ml/L of micro, 2.4 ml/L of grow.
If you're more at the stage of preflowers explosive growth then 2ml/l grow 2ml/l micro and 1.5ml/l of bloom
I hope that helps a little bit and you can get all your data on here soon.
As for myself with NPK, I always have my NPK near a 6-4-4 in the beginning, then into flowering I'm more at an NPK ratio of 2-8-4
Best of luck to you.
