Leaves Yellowing? What to do? (pics)

The newest sets of leaves coming in on my babies are yellowing pretty bad. Is it lack of nutes? Do I need to transplant them into bigger pots with fresh soil already? Over or under watering maybe? They are about 2 weeks old.

Also why has the one at the bottom right stopped growing altogether for the last week and a half? It doesn't appear to be dead.

Hey buc, those new leaves aren't coming in yellow, the old leaves are turning yellow. This would be normal. HUH? It would be normal for a plant that is not being given what it needs to start shedding the lower, oldest leaves trying to protect itself from dying. There are some folks in the forum that may be able to tell you what is wrong without the details of the grow, I am not one of them. From what I am seeing, the short stature, close leave nodes, they are not getting enough of anything. If you provide the details of your physical setup, nute schedule etc. we may be able to help. I imagine all of that information is in your journal?? This question belongs there too. VV

I haven't been giving them any nutes yet as they are only 2 weeks old. I thought I shouldn't be giving them any yet? I give each of them about a 1/5 of a cup of water every other day. 18 hours of light under 600 watt MH conversion bulb. Temps are between 83 and 85F. Humidity around 40%. Sorry for not posting enough details.

Type of soil and ph?

i would say nitrogen deficiency because your plants are yellowing with stunted growth. i had the same thing going on. for an organic fix to your problem, just add some wet, used coffee grounds into the soil. coffee grounds are a very good source of natural n2

i would give them half strength nutes. i too have problem in later stages which people are saying thas normal but i think some co2 would hurt ether. so definitly give half nutes hey what do u have for soil , tree bark?

Without knowing the ph of the soil/water and type of soil this isnt helpful advice. High alkalinity in soil or water causes iron deficiency and so therefore yellowing leaves and stunted growth etc etc etc, still too many parameters need investigating b4 you start advising nutes and the like.

Thank you Woomeister. The pH of the soil is 7.0 and the soil is Sta-Green Moisture Max Potting Mix with .14-.11-.08. I don't like the soil because of all the stupid woodchips in it and probably won't use it again.

Anyone have any suggestions?

what is your watering cycle?

I water every other day about a 1/5 cup per plant. I was giving them more, but was told it was too much.

Should I remove the yellow leaves or leave them on??

Thanks in advance.

Now the leaves are starting to droop a little. Is this normal?

Well it definitely was a nutrient deficiency already. I gave each of them about 1/3 cup of water with the recommended dose of Foxfarm and they all perked right up! Thanks everyone.

Thats great, how will you know if its underwatering or nute deficient? VV
