Not too long to go. Plenty of brown trich's around, but pistils still mostly white. Will probably be my last feed and will start with only plain water from now with the aim to chop in 10 days or so, maybe a little longer. This will take me to 8 weeks of flowering.
Congratulations on the harvest! For the first time I used my QB304 @ 110W to grow LSD-25. Unfortunately, I ran into a deficiency which more likely stunted her growth. I'll be using the same setup again and see what the quantum boards really do.
I'm looking forward to your next grow 👍
@Short_N_stockY, Cheers! Once you dial it in, i think you'll love it.
I'm getting close to 1g per watt with a full tent, last grow was 135g total at 150w. I too ran into deficiencies in my first grow with the QB's, but i wasn't testing ph and i think i had a bunch of other newbie problems as well. My last 3 runs have been great.
Yes you are correct, the website says higher than 7.6 to lower. But if i use straight 8.5 tap water and add the 3.5ml/l of Bio Flores, it comes down to around 5.7, so i never saw the need to lower it or it would end up in the 4's.
I think the cal mag need comes more from your medium and light source. Coco apparently needs a great deal of cal mag added, as it doesn't provide any. I use Canna soilless mix which has some coco, plus using LED, so i choose to use it.
As far as lowering, i just use standard ph up/down. I know these aren't organic, but it's what i could find at the time and it works well using 1 or 2 drops.
@evilsurfer, I'm using An current and adding cal mag.. Thing is my tap water is mad hard, So I'm thinking if I go bio all the way maybe I dont need to add cal mag..
.And yes what did you use for lowering ph?? If i give them only water I lover it with lime acid...
P.s: I think I read on their website if your ph is higher than 7.6 we need to lower it..
@CovikLaFlaire, I found that with my tap water (Ph 8.6) using the old Bio line i had to adjust, as the ph would come out around 4.something with the Bio Flores. They seemed to be using a new formula now as the nitrogen levels have been upped in the Flores (Which are now actually higher than the old bottle of Bio Vega i have) and when i follow the feed chart my ph comes out around 5.6-5.7.
They do say there's no need to adjust, but i always like to check anyway.
As far as cal mag, i use it every second watering as a precaution. I had issues with my first grow so i started using it, but am unsure if it contributed to better results or if i just got better as a grower. It's so cheap that i just use it anyway, and you need so little of it. General consensus is that you need it with LED so that's good enough for me.
I did 1 ml/l every second watering from early veg and then i did .5 ml/l every second watering in the last 4 weeks or so.
