nute strength

[avs]

Hi stoners

I'm in the early stages of a coco/perlite grow with Growth Technology coco nutes. Seedlings are 5 days old sativa and i'm feeding them 1/2 strength nutes as per directions on the bottle with a drop of superthrive. Problem is my ppm reading is only 600 at this strength. Seems a bit low to me

 

What do ya reckon guys? Should i up the strength a bit?

im girl when it comes to dossing the girls up i go with low PPM's some will say 600 is fine for your seedlings persoannly i would go around 200-300 PPM they look like there bairly cracked the seeds so slow and steady IMO no need to rush things

yeah avs superthrive is good stuff but use it sparingly on the yungins ,get some seawead extract ,i did that with mine and they loved it .slow and steady at this stage mate they love the sun at this time of year.....see ya sundy....space

Cheers fellas. I'll keep a close eye on them and might even start a diary later.

Well i've been stickin with the half strength nutes at around 600ppm and they seem to be doing fine. Aaaawwwe they're so young and impressionable........

What's the e.c. of that reading? (a true measure of strength as opposed to a mathematical conversion of e.c.) Depending on the ppm meter you could be talking about 0.8 odd ec in the 700 scale or 1.2 ec if it's in the 500 scale....

 

Young plants don't need much. They'll soon tell ya when you're not giving them enough anyway.

 

Looking good buddy.

What's the e.c. of that reading?

 

My meter only reads in PPM and i don't know if it uses the 500 or 700 scale. Its only a $30 pen type instrument.

Hi all time for an update i think. Been a bit of a pussy with the nutes keeping at around 1100ppm & haven't had any probs.

 

 

First shot is Red Devil/Hash plant which has been topped and LST'd.

 

 

2nd shot is the Afghan both are at 5 weeks flowering and being fed some PK 13/14 this week

 

 

Here is my box 900x500 i'm using air cooled hood with a 150mm inline axial plus a 120mm axial for intake. Got another Afghan from seed plus a hawian fantasy clone in there too its a bit crowded

 

All comments welcome.

looking good.,. i would have thought at 1100ppm thered be some yellowing of the leaves.. but its looking real healthy... and sticky..
