Very Yellow and Small PLEASE HELP!!

MY 8 plants are almost 3 weeks old from when the seeds went in the ground. The tallest one is MAYBE 5 inches tall but the smallest one is barely pushing 3 inches. The lower leaves are VERY yellow on all the plants and they haven't really grown that much in the past week.

They are in 6 inch pots in 18/6 under a 400w HPS. A fan is always blowing on them. I have been watering them with distilled tap water and they are growing in a soiless mix of peat moss and perlite. I think i might have been overwatering them for the first week and a half so i figured that might have hurt them a little but they STILL look as described b4 even after fixing that problem. Also i had been giving them small amounts of big bloom and this morning i gave them a fairly high dose (accidentally) of big bloom and grow big. There are not signs of nute burn but it looks like they are lacking nutes. I have given as much info as i can think of so PLEASE HELP!!!!!!!!!!!!!!!!!!!!!


p.s. it feels like its getting pretty hot so iam going to start giving it Co2 today or tmrw.

any1????????? they look RLY desperate.

Well it sounds like they needed the nutes, but you identified the problem and fixed it already. So just be patient now.
Peace

how fast should they recover though - i fed them at about 8 this mornign and still have not shown any difference? and how can i continue to give them the nutes they want without over watering???

Just wait until they actually need the next watering, than if you desire, give em nutes at that watering.
Peace

sounds good - they are just sooooo small i feel like they need something else.

They need your love dude.
Peace

THat is what we all need but those those plants don't need MORE nutes man.
The distilled tap water is probably 8.5 or 5.0 ph.
Control what you can control dude.

What is the ph of that water you use anyways ?

i cant ph test

Exactly. Give them time. Marijuana is an amazingly resilient plant.

When mine done that it was the heat.

Check the temp and try to keep it below 78 deg f

It's very common for the lower leaves to turn yellow and die. Plants are like people, in the sense they come in different sizes, are stronger or weaker, there is no guarantee that you'll get the same results from every seed.
Finally, your light might be the problem. Vegging is typically done under floro or MH lights, HPS is better for flowering.

You can and you will if you want to grow good pot.
