What am I doing wrong?

Hi Everyone! this is my first post, I have spent the last month or so reading through all the wonderful information on this site. My plants are about 3 weeks old and the leaves are starting to get droopy. I was hoping somone could help me out. It is a cabinet grow 4'X2'X5' with 400w hps. We have an ac unit blowing cold air into the cabinet as well as two passive vent holes. The fan we have is a 265cfm, which pulls through the light. Hopefully that makes sense, my husband built it and I just take care of the plants.

E-indoor or outdoor Indoor
E-soil, soilless, coco, aero, or hydroponic soil
CSL-Soil type/brand 2/3 FFOF 1/3 perlite
SCL-Anything you have added to the soil FF Grow Big 1/4 strength
SCLR-Soil or slab runoff pH have not tested run off
E-Water source RO Water
E-Source water pH 6.0
E-Age of plant 3 weeks
E-Type of fertilizer FF grow big 1/4 strength
E-Rate of application (if hydro, this is your PPM number, preferably after each component is added)
E-Lighting source and distance from plant 400w HPS. 6 inches away
E-Air temperature (both day and night if you are running a dark period) day temp max 84 night temp 68. running 18/6
E-Air % Relative humidity 30%
E-Lighting schedule 18/6
E-Type of ventilation your room has ac inline, 2 passive vents. 265cfm

It seems to me buddy that you are watering the fuck out of it...make sure the soil is dry before giving the little baby another drink

Welcome riley22

I would have to agree with SunnyD.
Also I would bring the water PH up a bit.
I personally use PH 6.5 with good results
And then I would put my hand on top of my plants for a minute or 2 to see if it gets hot.
If your hand gets hot so will your plants.
GOOD LUCK

good lord your drowning them !! let them dry out maybe put more holes in pot ... goodluck also that light is prolly to close HOT!!

Thank you everyone I will let them dry out before I water again. The temp at plant level right now is 81 degrees, is that still too hot?

I went through something simular. It really want hurt to go without watering. Let the get dry. It may take a couple of days or more.

It might just be me, but im pretty sure the light is to close especially for little plants. I would say at least a foot away. Could be overwatering too though. Mabey that will help.

Now THAT'S how to fill-out a troubleshooting form, ^^^ lol. (gotta love the "bold" responses) :thumbsup::thumbsup:

ph is low. You'll want to raise it a bit to around 6.6 to 6.8 for soil.
Too small for nutes yet. You may want to flush them once they've dried-out a bit.
Overwatering (already mentioned)
R/O water will need a CalMag type of suppliment.
Light may be too close for seedlings/clones unless it's very well cooled. Especially if they are stressed. (which they are) When you put your hand just above the canopy, (back of hand twords the light) if your hand get's too warm, it's too warm for the seedlings.

OK...so I let them dry out and flushed them today with just tap water. I also moved them down to about 12 inches from the light. Will the leaves eventually spring back up?
