HPA Flora Series General Hydroponic dosage.

Hi All,
Can someone point me in the right direction for the correct nutrient schedule for Flora Series General Hydroponic grow/micro/bloom in an HPA system. Plenty of info on Hydroponic but not much on High pressure aeroponics. Perhaps an updated nutrient schedule by someone who has first hand experience.
The standard hydro mix chart on the bottle of 0.5ml per liter of each is extremely hot and even at a 50% reduction completely cooks three week old seedlings.

Thank you.

Do you understand how hydroponics works?

You don’t follow a feed chart you monitor your reservoir.

You should be looking at PPM increases and decrease along with pH drifts to determine if you need to increase ppm or pH or decrease etc.

1:1:1 ratio is great for veg stage

then switch to Lucas for bloom (1:2)

.5ml/liter of MGB is a very low dose, around 0.5 EC
0.5EC is not gonna cause any nute burning
Your problem likely lies elsewhere
What's the EC after adding the nutes to your water?

Do you understand how hydroponics works? Yes I've had several different RDWC systems that I've experimented with.

You don’t follow a feed chart you monitor your reservoir. I understand this. I was looking for a general starting point... 1/2 or 1/4 the recommended hydro dose.

You should be looking at PPM increases and decrease along with pH drifts to determine if you need to increase ppm or pH or decrease etc.

I'm looking for these values/estimates from someone who has a HPA system up and running.

Nobody is going to drive your car for you
I think you are looking for a mentor
Good luck

No 2 systems will run exactly the same.

use what GH recommend for veg and for flower as far as mixing quantities goes and the rest is done by monitoring your reservoir.

What you’re asking for is step by step how much of each to add to your water week by week?

Im telling use what GH recommend for veg and flower BUT monitor your water statistics to see how they are feeding etc.

No one can say add 5ml of A/B and then 27ml of C into a gallon of water as your system and plants may differ to someone else’s.

Thanks for the input. I discovered "connoisseurquality" on reddit who has extensive knowledge and experiance in HPA systems. Long story short, the EC/PPM for an HPA system, for autoflowers needs to be as little as 1/8th of the recommended dosage. The image shows one of his HPA systems. He shared his type of nutes, nute dosage, spray schedule and temps etc. Fascinating at how efficient HPA is.

start a grow journal here when you get it going. HPA is fascinating to me

The growth is absolutely insane. Hard to believe this monster was as big as my thumb only a few weeks ago.



This root pic is 2 weeks old... they have filled the bucket now and are super fluffy.

you have any better pics of your hpa system? those roots are incredible

Here are two pics exactly a month apart - 23rd last month. The tall monster with all the buds is left center.

Ill be happy to send pics of my entire set up. I put a lot of thought into it before putting it together. I kept it nice and simple. Before this, I had never grown any marijuana plants before. I only have two nozzles per 50 liter tote. 6 second spray every 6 minutes @ 700 kPa. Extremally fine mist. The 6 50 liter totes fit perfectly into my 1,2m x 1,2 meter tent. I have a 30 liter reservoir. All 6 totes are raised with smaller totes upside down underneath. Each tote runs into a main line back to the reservoir. 650w LED, also 650w draw. I have both UV-A 360nm and UV-B 310nm and halogen all running at different intervals with the use of Sonoff controllers. Two silent series extractors are also connected to a Sonoff controller which keep temps at 25c. I have a Large dehumidifier which controls the humidity in the room. I force the temps down to 15c when they sleep for 6 hours as I believe (Dr. Bruce Bugbee) colder temps help with the nice purple tones. The pumps controllers are Riken, one for the long timer and one for short timer (I don't trust digital on the watering).

that's awesome! nice work. thanks for the pics too.

what do you estimate the whole aero system cost you to build?

Short answer...a shit load lol. I had nothing to start off with though, I didn't have or know what a PH pen was. I work in IT. I saw a little weed plant on the side of the road while walking one day and thought to myself, Id like to grow that. A month later I had the aeroponic system up and running. Id say I spent about 2000usd, once the dehumidifiers and air-conditioning was in probably closer to 3500 / 4000usd.
