Hmm, cant really figure out whats wrong

I think this is a nitrogen deficiency problem... they are about 3 weeks old and have no been fed any fertilizers, should i start?? Also, these plants have been on 24 hours light, and one is showing sex?? these are all Super Sour Silver Diesel Haze... So why is only one showing sex? Most of them are FEMM'ed... The starter soil did have VERY little nutrients. LET ME KNOW!

They look hungry, I would feed them a little, How are your temperatures?

My temperatures are in the high seventies, and there is a fan blowing on them constantly... I was thinking they are hungry too.

It looks to me like your plants are not getting enough light! If you had that one plant in the corner where it gets the least light for a while it might have caused it to try and start budding.

What kind of lights are you using/how many/how close? If those little CFL bulbs are your only light, they need to be closer! You also might want to get more than just 2 of them for that many plants. I don't know if that's all your lights or not, but that's all I can see in the pictures.

Also, with fluorescent lightbulbs, you need to get them REALLY close to the plants because the light does not penetrate very far out of that type of lightbulb. Depending on how hot those get, you can put them as close as 1-2 inches away from the tops of your plants.

See how close you can hold your hand to those bulbs for one whole minute without it feeling hot. A little warm is OK, just not hot. Then move the lights closer to that distance that you measured. You want them as close as you can without it being too hot!

I was also considering that an issue too... Those are two 65watts (300) equivelent, with 3,900 lumens each. The bulbs are at least 2 inches from each plant, and actually there are other plants that are further away from the plant that are doing just fine... If it is just a light issue, that should be fixed very soon, they are going outside Wednesday. Should i be using any nutrients? I have been told super thrive would be very helpful right now...

So weird, I just posted a similar thread an hour after you, one of my 2 week olds under 24 hour light is showing male flowers...I'll be sure to watch this thread as well. Get 2 birds stoned at once.

Yes, if they are 3 weeks old I'd say it is time for their first feeding. You should start at 1/2 strength for the first time and then work your way up to full strength. That Superthrive is not meant to be used as your only fertilizer, you should also get a good Grow and a good Bloom fertilizer to use during your veg. and bud cycles.

Also, don't just one day put those outside in full sun all day. Since they have been getting such low light from only those 2 little bulbs it would be a big shock for them to all the sudden get hours and hours of full sun. Put them out for a couple hours a day at first, and gradually build them up over a week or so to be able to stay out all the time.

Alright, thanks alot for your help! ill post pictures soon and show you how they are getting. Im going to the hydro store to get superthrive and a veggy fertilizer
