the reason you have an n def is because you are not watering enough so the plant cant get any food. feed it more even if it means less often so it dries to.

Ok thanks! I will give that a try and see how they develop. I guess i was under watering out of fear of over watering like last bunch

as long as the cotyldons are green there is enough food for the seedling to thrive until it cn produce food via photosynthesis. You dont feed them anything but 1 drop of superthrive per gallon maby on the end of the second week until 4th and 5th node you can start feeding nutes.
Im in the same boat. I have 8 stunted seedlings going into thier 2nd week and only 2 sets of leaves. Im doing eveything right, they simply are growing at a veryvery slow rate.

SO last night i gave them all a very good feed, hope it helps.

Browning has developed a little more since yesterday looks like they are heading towards the same fate as my first grow.

I am using this light on them as close as i can get it to them:
130 watt self ballasted grow grolights lighting plants envirolites cool queensland Australia Gold Coast

I just realised though that they are probably over heating... it is winter here and my wife likes the house to be around 23 degrees, i am thinking that the ducted heating might be drying them out, and causing them to suffer heat stress so I have blocked the hot air from entering the room, opened the windows and hopefully that will do them some good.

Meantime more seeds on the way just in case.. ill stop by the hydro shop next weekend see what better soil they recomend.

BTW i thought that 3-4 tablespoons of water a day would be plenty?

So long story short water those more and start with like 15%-25% nutrients.
Your plants look dry as another poster said, and also are eating themselves for nutrients IMHO. I have nutrient burn on my babies and it is different looking. Yours is a water and nitrogen deficiency where as mine is a burn from too much nutrients I will get you some pics since e both have seedlings and can see the difference more easily.

This guy is right on the mark.

everything? really?

Please feed those plants with a ppm of 2-300, and ph your water @ 6-6.5. I am suspecting that since you have a soil medium that dose not have any nutrient that you are using Coco. Next time mix in some perlite into the coco, this helps alot with keeping the oxygen levels high. As far as your watering goes, look at these 3 things, is the plant starting to wilt?
is the container exceptionaly light? you will learn the correct weight in time.
if you stick your finger into the soil, is there any moisture an inch into the soil? if not, probobly time to water. Just remember this simple rule...The reason you don't keep the soil saturated all the time is that the oxygen levels go down when you water. The plants root system does best half way through its feeding cycle. After that it starts to decline due to lack of.....you guessed it water! So try to fully saturate your containers so you don't get dry pockets in the soil, then let then dry out until the plant starts to show signs that it is thirsty "wilting". At this time feel the weight of the container, and from that point on you have a reference point. oh yeah "nutes"=fertilizer...Feed them! Do you have any nutrient yet?

Great advice!!! Thanks so much for taking the time.

Damn little seedlings are fragile, thought this thing was meant to be a weed.

Once they develop a healthy root system, they can recover from just about anything..GL, I plan to watch to see how you are doing, so if you have questions I will probably be around to help you out...And hopefully there is some others around here that will give you sound advice and get you through this learning curve with out to many pit falls...

Thanks mate! I shall be here for a while i suspect!

They are actually looking a little better tonight, I think i know what else might be bothering the ones that are burning... i didnt change the soil since the last batch that I over nuted (yes yet another rookie mistake right), so i suspect a couple of them are actually being burnt.

we'll see how they go. non the less fem seeds on the way just in case.

the best thing u can give them is time dude, water them wen the soil is dry and wait till they grow. Dont worrie bout nute till the plants tell u they need feeding, id personaly wait till at least 4 weeks old and then only 1/4 strength. Good luck man, what fem seeds u got coming? did u buy single seeds?

I've only read ur post, haven't read any replies coz in a rush, but at first glance they appear to have a Nitrogen (N) deficiency coming on and are either being over or under watered.

I recommend you get some standard potting mix (like in a 20L bag from local garden center), pot them in this in a small container and water every day of two with about 20ml of water (don't add nutes coz they won't need any, other than what's already in the soil, until they have their first 5 finger leaves).

Cheers.
