First hydro grow (white russian)

This is my first grow and went for 3X 20ltr D/W/C buckets + 400 watt Hps
nuts
cana flora A+B
cana veg A+B
cana pk 13/14
i keep closet temp at 80 light on 77 off
i live in a hard water area and the ppm of my tap water is 800 + ph of 7.1
i have 5 white russian + 4 unknown

ph of all buckets is 5.9
ppm all buckets 1000
these were started from seed on 20/08/09
here are some pics as i think i have a pb with the unkown seeds
1. ive thought of reducing nuts but any input would be great



the white russians are loving it buy the looks of things but need all the help i can get to keep them that way lol




also when would be the best time to flower
any help would be great as i dont want to lose them cheers


ill update pics every few days just to be sure there ok

nice setup. looks good man.

Just a side note, my friend who grows started using the little foam inserts over his pots, and his resovoir temp dropped a few degrees. As far as nutes, I see no burn, I say keep feeding them as you are. Wait til you get preflowers forming to switch to 12/12 if you are taking those directly to flower with no topping or anything.

i was going to let them get to about 13in then start to flower 12/12 but is it better to let the pre flowers to show first ?
cheers for all the help

Congrats Bifta

Looking good there so far ... One bit of advise don't kill your plants by being an over bearing parent. One of the things i have seen and have actually done myself is over analyze your plants.

Your plants look great and there is no need to panic if you see a little spot on a leaf . Do the research on what it is and fix the problem.

If you have done your research and continue to do it learning everything you can about your next phaze of growth you will be fine.

Keep us posted

cheers sparkafire i no wot you are saying lol im doing my best not to keep looking at them it was just all the unkown plants are the same strain and seem to wilting a bit even new growth any ideas or should i stop being a fool lol
cheers m8

you said your PPM is 1000 your water is 800 you did account for the the 800 right?

well yes i split water ppm in half so my base was 400 then added 1000 ppm canna veg A+B
the white russians are loving it but the unkown might be getting a bit to much

If you started at 400 and your PPM in your tank is 1000 your true ppm is 600?

If your water is 800ppm to start with your ppm should be 1800 for a true 1000 ppm reading.

ah ok m8 just dipped my ppm meter in all buckets and getting 1400 ppm so my true reading is 600 ppm as 800 is tap water

There you go!! your plants look great bump up the nutes a bit and see what happens. You will be suprized as to how much they will take on. Just make sure you do your math correctly you have a confusing ppm set up with the water and all. double check your math and you will be fine. I only say that because i am a tard when it comes to math. yes i have dumped a whole tub of nutes because i cant count.

i dont think ill up nuts yet m8 still a bit young 3 weeks and 600 ppm seems to be about right for white russian as they dont mind a bit extra nuts but the other 4 needs to be about 300 ppm
ill up new pics in a bit

also with the tap water the ppm is 800 but at least 50% of this is undissolved salts and dont do anything for the plants so i have read thats why i halve the 800 ppm as i no 400 ppm will be used hope this makes sense m8

Yes it is clearer and makes sense. at 3 weeks you should be able to jump up the nutes though at least to 1200 or so. Why do you think the other plants need less nutes? I am learning here as well just want to know your thoughts on it .

ill up a few pics in a minute i think they are struggling a bit at 600 ppm also they have been getting this from seed they just dont look as healthy as the russians leaves are curling upwards but you will see wot i mean in a bit light go out in 8 mins then ill get some snaps to show you

No we don't want to burn them !! just want to make a educated choice as to what you want to do.

thats it m8 by the way thanks for all the help otherwise i would be second guessing everything and thats where it starts to go wrong lol

As you say down there No worries Mate!! Think about playing with the nutes though.
