Hey guys, long time reader, first time poster.
Would love some tech support with my first grow please!!!
I have sprouted these 3 seeds about 3 weeks ago.

Temp: 25 degrees
Constant fresh air,
and fan blowing on them.
Ph of 6
Using canna part A+B nutrience at about 1.5mill each per Litre at the moment. Feeding plants about every 2-3days with about 50mill
Using a 700w hps bulb.

They just are not growing!!?? And im stuck on why. Any help much appreciated
One plants leaves going a bit droopy, it was doing this as i was over watering so i didnt water it for about 4 days and still no luck.

damn 700watt hps? that might be a little too much for your seedlings. try a t5 florescent warm light u can get a small one at homedepot for like 27$ with bulbs included. use that instead and save on electricity too. just use it till theyre ready to fully veg ( around 2-3weeks depending on your liking ). meanwhile u can look into changing into something more with blue spectrum light to help them grow out better...

also how much nutrients are you feeding at this stage of life? they dont need any nutrients just water is good.

25 degrees Fahrenheit??? jesus dude thats super cold. :? i would turn off the fans...

youre hella wasting the 700watt bulb on them man i would keep them under the cfls you would even save up some money too. never grown with cfls before wish i could help you more there. feed them water only, theyre at a pretty young stage of life still. patience my friend try to forget about them let them do their thing! your temps are perfect.

Umm for sure the 700w is not the problem so dont go searching there. I have had plants the same size under 1000w no problem.

why tho..? if you can afford using a 700watt hps for your seedlings you can surely afford a 400watt metal halide at least. :wall: i would highly recommend him not to use it and just have him switch to the cfls.... you really want him running that 700watt throughout his whole plants life cycle? what if he gets 1 female, heck what if he gets no females lol. just trying to give out the best advice possible. crossing my fingers he's using feminized seeds.

Sory guys, my bad... its a 315w metal halide..
Im going to just raise the light a bit to keep it warm in there, and water it without nutrience for a while and see how it goes.
Cheers for your replys
And yes they are all fem seeds

What im saying is that he says he is having issues and is questioning if its too much light. I am just letting you know thats not too much light

Look at those leaves as I am going to THC university those leaves are turning yellow ( sucker leafs) in my experience in class u have a (low nitrogen dif) seedling only need lil light throw this stage for about 3 weeks 2 26 watt CFL would do the trick I would feed them 1/4 strength nitrogen use like fox farm or other organic fertilizers. What's ur ppm and I agree that light gives off a yellow color M.L would give a blue spectrom of color

very nice, prices are hella dropping on LEDs on amazon thats good. my friend hooked it up with this tiny LED bulb that cost him 26$ not even enough to cover half of a plant. i could clearly tell the nodes exploding with growth compared to the other girls in the room.
