I did check the pics and the plants look pretty damn healthy, but they are a little on the small side and could possibly be a bit thicker?
But it sounds like you did everything perfect for a coco grow... I wouldnt change a thing as far as the methods you used (EC, ect.) BUT I am surprised you didnt have any micro deficiencies using just A/B and PK...
If you want to try adding some supplements, you may be able to increase yield and density... Cal/mag would be my first suggestion since your using rain water and it will increase cell density (use a low steady dose through the entire bloom cycle and also in veg if needed)... Always add anything with Calcium first, THEN add your nutes after ... U would probably benefit from some Micros as well.
I also like using Gravity with a little sugar starting right after the PK 13/14.
Inoculating with beneficial bacteria also seems to help quite a bit.
I use a lot of additives, supplements, beneficial bacteria, ect. but its up to you if you want to go down that route because you can get by without them. Keep in mind that most additives dont work that well unless all the environmental conditions (Temps. RH, ect.) are just right.
What type of lighting and strains are you running? How many ML per Gal are you using of the Canna A/B?
what else do want to know?
thanks for the reply man, much appreciated..
They are whiteberry from paradise, they arent renowned for big yields but there also not small yielders.. And yes i agree with u about being small for 5weekers, also the stems are flimsy..
Im in australia and havnt found any cal/mag readily available although i hvnt really looked if that makes sense, but it has been on my mind since im using rainwater..
(use a low steady dose through the entire bloom cycle and also in veg if needed)... Always add anything with Calcium first, THEN add your nutes after ...
this is exactly wot im looking for, this info i will use..
The Gravity, once again im in Aus ill be looking for the equivalent if its not available..
Im running 2x1000hps in a about 7'x 8' room, theres a couple more strains in there but im only concerned about the WB.. I run co2 at 28-29 degrees celcius, no intake or vent fans, between 40-60% RH.. Bcos i run my lights during the night, the plants night cycle is my daytime so temps stay pretty constant 28-29, even thru lights off, and humidity has been around 100% during lights off too, which ive fixed by cycling my AC during lights off..
so yeh theres some less then ideal things right there
As for how many mls of a/b im not sure, really, i just keep dosing until i get up to 2.2
And thats really it man, ur comment about Gravity is funny actually bcos i started a thread on a different forum about suggestions of wot to use after i finished with the PK, especially bcos i used the PK so early, ive had another 6-7 weeks to kill without any other additives, but at the same time i dont want to spend massive $$$ id just as soon use nothing..
Thanks again man
