I need help, my bottom nodes are turning yellow and curling. At the top node, the two biggest leaves are slightly turning yellow. Any information will help. Here are some pictures.
Thanks

I water every other day 200 ml.
And the temperature, I don't know.
I have two fans though as you can see in the picture, one fan bringing in cold air and the other sucking out hot air.
I can get the temperature in a few minutes though.

What kind of Soil.. Have you used any Nutes.. and Whats the PH of the Water you use??

Ive got the same kinda Meter.. it doesnt test the PH of the soil when you just stick it in.. Get one of those Swimming pool testers and test the Run off of the Water after you water the plant.

What kind of light is that?

Other than the light i can really think of anything that would affect the plant that much since you prolly havent added anything to it.. Aside from the Dolomite Lime..

Are you measureing the PH after each watering? Its possible your fluxuating the PH too much and its affecting the plant because its so young.

i would say the light is way to far away (you want the light as close to the plant as possible with out burning it), the fans are to little (one fan should be on the top to take out the hot air and another on the bottom to bring in cool air).

my guess is your plant is a week 1/2 or 2 weeks old, i would not use any nutes yet, thats why i would change the soil.
MG is not the best soil to use try to find some thing with out time release nutes in it.

the leaves on the bottom are going to trun and fall of its okay.

what kind of light are you running?

Get a small fan to blow directly on the plant to make the stock stronger to help support its-self durring flowering.

what should I use?

If.. the problem is the light.. get a 23w+ CFL or a few.. 6500k Daylight.. until the plant gets a little bigger.. Then switch it back over to what you have there.

Just a guess though.. Im growing with CFLs from start to harvest.. so its not 100% Accurate.

do you have any preference of soil to use that is easily accessible? and to get u correctly, i should run 3 fans? one on top by the light one on bottom for cool air and one in the middle directly oin the plant? and what if i put a sheet of thin glass to separate the light from the plant, and the light is 18" from the top of the plant

your PH is off...this is pretty consistent problem with miracle grow...its great on my plumeria's...but not good for growing bud. You'll be way better off in the Ph department using higher quality soil. look up a local hydro store and pick up some soil there. ive been using foxfarm soil for a while with great success...its already mixed with perlite and is ready for use right out of the bag..ph of 6.0-6.3 is my target range.

as far as your lighting goes...im surprised your not having heat issues with your 400W hps...looking at your setup..i think you'd benefit from connecting ducting from your intake fan to your light and back out of your exhaust. another intake/exhaust fan for the room and a tabletop fan directly on the plants should be able to.

good luck and hope this helps a lil atleast

the light you have is just fine that is what i am runing at this time for my seedlings. put the palm of your hand on top of the plant and see if gets hot, if uncomfortably hot then raise the light till you can keep your hand there. as for soil i used jiffy seed starting mix organics for home depot. like $5.00. as for fans the hot air will raise so one exhaust fan needs to be above light to remove heat from light and hot air build up. Another, intake fan as close to floor level as possible to bring in cool air. And a 3rd like a small portable fan to blow air on the plants (you can get on at home depot for $10.00) ((I have 2 in my room)). When you change the soil your ph should level out.
