My plants are just over a week old now ,and seem to be going yellow through the middle , there are yellow line's appearing on the vains of the leave's and little patches as well as leaves looking a little yellow, tips are also yellow !,. On a different plant the leave's are very dark in colour and looked waxed also with yellow tip's and also some tips are faceing down??? ..... ...Here is a few thing's i'm Rating: 5

yep for sure (MB) MOLYBDENUM Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb

(MN)MANGANESEN yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn
this may not be problem sometimes this could just be over waterring
try get some pics from other angles as for ph you want guy called rusty he shoud be on later
digital tester is always better but im sure you can get a good enoth reading of of that
and if ph is out this could cause this

[jaydee84]

as far as PH goes i no that 6-7 is ok i think 6.5 is a good number

[jaydee84]

as for superthrive yea take it away for a bit not too clued up on superthrive i think its good for clones/cutting but small doses dont over do it
i could be wrong about what you would use superthrive for but i think it is

oh ok...i take it ur 600watt is hps 2 foot is ok do you have a fan pointing over plants to take the heat away... do the leaves feel dried out?
you say 6.5 ph im sure this is ok is your water boiled or straight from tap

[jaydee84]

also you said.....quote>When i turn the lights off i turn everything off , i.e fan filtter fresh air ! Should i or should leave on ??

yes i would leave it on with my grow i used to turn fan of like what your doing was ok but then i done some xtra sealing around door's to cut down lite leak etc they started going bit droopy i was advised to keep them on 24/7 and yes it made the difference
if they are starving from fresh air it would make them sad droop etc

The water is straight from tap , my tap water is ph 7.1 , , my temp is 39.2 , and humid is 33% with lights on

And no my fan is well away from the plants at the top of the tent , and is not directed straight at the plants but across the ten , is this wrong ??

ok you should use boiled then cooled water
for starters....AND IS THAT 39,2C IF SO THIS IS TOO HOT should be around 25-27c roughly.....as for fan if you can get it so it directs the heat away from the plant

38-39 Is the best i can get it ! , will this cause a problem in growing? or anything else for that matter?

I moved the fan and is aiming directly under the light now ! that should help a little with the heat once that settles i think ?,... i just went a bought myself a ph meter and a thermometer, so that should help me a bit?

Hydrometer? Does this read the humidity? if so which is good Day & Night?

And boiling the water , Doesnt that get rid of some stuff that plants need? if so i will have to replace??
