What's causing discoloring on leaves

Hey, I was curious if anyone could help me figure out what's making my plants change colors on lower leaves - drooping. It is some indica bagseed was growing under some CFLs. I Moved to a 600 Watt hid mh. It's being grown in a 2 Gallon Pot with Coco Coir - General Hydro. I water when the coco is dry about one inch down.

it's about three weeks old I have three others much healthier and then I have two dieing and one I am pretty sure is dead. The one that is dead I am not sure what happened to it, but it looks like the same beginning stages with these other two starting to discolor - droop. I water whenn they are dry - 1 inch down

If anyone has any information that could be useful to me I would appreciate it very much.

Thanks


Also I wasn't sure how to remove my own post but I figured my question is more suited for this section.

Looks like a Nitrogen deficiency imho. Lower leaves turning yellow like that is usually an N deficiency. What exact nutes are you feeding and how often?

I would say so too.
Other things to consider, you've made a massive leap from clfs to 600w MH, make sure your lights not too close and give us some info on temps and RH if you can. Also what is the ph of your nutrients when feeding?
Where in relation to how your plants are situated under the light have you seen the worst symptoms? As in were the ones that died in the center or at the edge?

I am going off the schedule In the picture I attached Sourced from a growweedeasy guide. For the most part sticking with what this guide says but there have been days where the Coco is still wet and I will let it dry up only was a few days.

Yeah, but the one that is most shitty looking - dead never made the transition. He died off early. I noticed the light being an issue early on for me but It became pretty obvious when the leafs were curling I quickly fixed temp - distance situation. The temps are anywhere from 73°-80°(rarely that high) generally. RH usually 45-55 I kept the humidity higher during seedling(70ish). The PH of my water nutes after I added everything in ill level it out to 6. Position didn't seem to make any difference with the symptoms. Most of the good looking ones are not anywhere specific some center some outside edge. but the position of the one I care about saving the most right now is center.

I read more into this a little and I would agree very good chance that's the issue. I know week 1 it got over nuted my roommate mixed nutes in a 2 liter for the plants didn't seem any different next few days to be honest. only noticed these issues like week 2 so I am not sure if it is related.

Seems like your PH temp and rh are not the problem then. The only thing I can think if your lights not too close and all the above is in good range is overwatering. Roughly 2 of your gallons(our gallons are 5ltr) is around 7.5 ltr. If your light is drying out your coco with the help of good airflow rather than your roots actually drying it out or drinking it up then you could be overwatering and damaging roots. They look fairly young. Let the pot dry out considerably and feel the weight of the pot rather than measuring the dryness on the top inch or two of coco. The roots dying or not been in good condition would explain a lot. Give them some time, that's the only thing that can bring back your root system... It will take a while. You could also aid the root system by adding some H2O2 like oxyplus to your next feed. Just be careful to no overdo it and follow the instructions.
