Thanks man, appreciate that!
So I’m using the
canna coco nutrient line which is a 2 part line for the whole cycle, canna a and b and the same canna a and b is used throughout the whole cycle, I will be changing this on the next one so I can dial down my ratios better when I add perlite for drainage.
Back to this crop, canna suggest that when you have soft water, to add their canna
calmag and bring the ec to 0.4 before adding other nutrients.
My water comes in at 0.2 so I add the required amount to make the solution 0.4 ec.
Checked my local water supply and these are the numbers
Then I add my base nutrients and other additives.
Now I checked my last nutrient res and I’m pretty sure it was around 1.2 ec which is very low so I think that sure did have a big part to play.
Dr Bruce bugbee, a plant scientist states you should always under feed rather than overfeed and I may have took that too seriously lol.
Now with regards to the ratios of K/Ca or K/Mg or any other ratios I honestly don’t have a clue. I just roughly follow the feed chart and try to keep my ph now around 6.0 and 5.8 previously in veg.
I’ve not really done much in depth research on nutrients yet as obviously there are so many aspects to growing good quality shit but I’ll definitely need to if I want to dial things in.
Yh exactly 2 weeks, today is day 15 after the flip and I have just fed them at 1.8 ec so hopefully will see a difference.
Yes 600w hps lights at around similar ppfd to the leds, ranging from 900 to 1300 ppfd at canopy.
I have however only brought in the leds like a week ago to help control temps as only hps was just too much. So the leds were introduced on around day 7 of flower, not sure if the sudden change may have interrupted them in any way.
Room is sealed with no intakes or exhausts, I run air conditioning, humidification, dehumidification and heating for full control.
Air flow is pretty good so air temps are even around the room. However, canopy of the hps are a little hotter obviously with all the infrared.
At the moment I’m running my room at 28 d c and 60 percent humidity.
I don’t have any normal lights in the room but I’ve just taken a few leaves from under the hps and placed them under the leds and have realised they are very similar lol, the orange light is very misleading, I would say the leds still do look a little worse off but I’d only know if I placed the led light over the canopy of the hps I guess.
Thanks for the help by the way, really do appreciate it!
