Impending sense of doom

I have two different strains both bought from the same dispensary. 6 plants per strain. They were both bought and put under my lights on the 17th of September. I put them into 4 inch pots with Fox Farm Ocean Forest. I know that is a little hot but since they were almost a month old already with strong roots I figured they would do fine. I have been watering about every other day when the dirt is dry down to my first knuckle and my hydrometer says the soil is dry down deep. I have only been watering with PH balanced water until today. Today I watered with a half strength Fox Farms Big Bloom solution. They are in 4 inch pots right now. Once they fill in with roots I will put into 5 gallon pots. I have 2 1000 watt ballasts. Right now I am using 1 1000 watt MH dimmed to 750 watts.(Aware of light shock) When I switch over to flowering I will use both lights at full blast. I also had my MH dimmed to 600 watts for a few days and just upped it a couple days ago. The light is over 2 feet above the canopy. The ambient air is about 75 degrees during the day and 65 at night in my grow room. The leaves are only about 74 degrees according to my inferred temp gauge. Yesterday I started low stress training so the plants look way worse than they did yesterday. There is lots of new growth but the older leaves don' t look perfect. Looking at my plants I just feel like something is wrong and that they are all going to die(Hopefully just first time grow worries). I have watched friends grow several times but never done it myself. I have read the cannabis bible and read so many forums here and around but just can't figure out what is going on. I also put in a picture of my room so you guys have an idea of what it looks like. In case anything is wrong in there....

EDIT: I just watered the pants when I had taken these pictures. I drained the tray so they were not sitting in water. Just an FYI

TLDR: Looking at the pictures of my plants, something just seems off. Any idea?

IMO=/ I'd potup up now to ur 5 gal pots

mixing in 20% perlite to ur FFOF

to offer some air and avoid root compaction

I see clones as some others work

next time please grow from seed

it makes it personal

always lift the pot before water, avoid ur current bull method

add 50/50 tap or some calmag to avoid Mg Def

good luck

I do not like vegging babies and even small teens any where near a MH 1000 watt lamps even dimmed WAY down. It is like putting the little plants in a microwave. No joke. Some dumb hippy told me to stick babies under MH. Yeah that works great. After 3 weeks of nothing, the baby plants died. I learned my lesson - probably thanks to a poster here on T8s and T5s.

You can get a T8 2 bulb at Wal Mart for $10.97 or a better one at Lowes for $18.99. The two bulbs are about $7 total for GE 6500 K that put out about 2900 lumens each. You will also use much less electricity. It may take a little longer to veg but you can put the T8 right on top of them or about 5 inches away. Alternatively, stick em under MH and fry em.

So you mean you got no growth for 3 weeks and then they just died? That seems very strange to me... What temps were you running? How close? Were they perfectly green for 3 weeks and just died one day? I am very very confused as to what occurred during those 3 weeks. Did you have the same symptoms that I have now?

They are growing well with lots and lots of new growth. Between 1/4 and 1/2 inch a day. The new leaves look great. Some of the old leaves just look a little deficient. I am thinking a cal/mag deficiency maybe. My temperatures appear to be in the ideal range and the risk of light shock seems to have passed. It appears that if done right MH is much better just more difficult to do correctly. So I think I am going to stick with MH, I have so much invested and dont really have room for more lights. I am curious as to why the old leaves are a bit droopy and yellow on the edges. From everything I have read it does not appear to be due to MH. I could be wrong. Can you relate as to why you feel the MH is causing my issues?

Next cycle I may try the T8 bulbs like your mentioned. I will read up on them. Thanks for the thoughts
