great pix guys...

cees im now starting my bluberry in a 4.5x8.9x7 room with 2 600 hid in cool tubes. I am utilizing a co2 injection system and have great ventilation temps and humidity never rise 75f / 45rh. the system im utilizing is dwc buckets , now the question is since im doing the 12/12 system how long should I use veg feed if at all. the nutes I have are rockwool formula a&b, pureblend grow and bloom,grotek monster bloom and advanced nutrients overdrive ...can anyone help me put these nutes together as pertaining to which nutes to use during which phases.

fyi these were all nutes I got from leftover from friends funny thing is all the seals were never broken so I got free nutes never even used....

[bullish84]

forgot to mention the medium im using which is all rockwool, I unfortunately could not get seeds so starting from clones that are 1 week old.

[Boss]

I suggest flowering nutes like racefan had said, they are better for rooting. Were the clones flowering or in veg?

[bullish84]

they are fresh cuts and just rooted in the rockwool cubes only 1 week old

[bullish84]

they are in veg

Well, I just can tell you what did bring us the most succes with fertilizing.
We're using ONLY flowering fertilizers and on side of that Guano-extract since we only use 12 hours light. The Guano extract does bring a lot of direct uptakeble and naturely Phosfhor, magnesium and calcium in our medium.
We're coming to at least 1.2 gram ( dry ) per watt with no nonsons talk.
Conclusion may be that we're doing fine.. I guess.
Sorry for my poor english guys.

so just to reiterate so i and everyone else understands you use only flower nutes and secondary nutes with high phophourous/mag/calcium correct?

as well how often would you suggest feeding with a hydro setup?

[Boss]

Cees, you must use a moderate N at start right? They say Nitrogen makes females.

See if this works, it's a great read.
