Under watering or nute problem....help???

So I got some Some pretty PK clones from a friend of mine and Im attempting to to grow them.
There a bout 4 weeks old,
Under a 400 watt Hps, its prety hot in in the room
In 1 gallon pot with canna terra professional soil,
watered/feed with Floragro by General Hydroponics 1 week ago.
They

These girls got extremely dry while I was away on a trip. I drenched them with a light Flora grow solution and ever since then they have stopped growing and started going down hill. Just wondering if you guys could help me figure out whats going on? There soil seems to dry out super fast and Im afraid of over watering.

Heres a few pics:

dont you love the fat ass leaves. haha

Im not sure of the exact temp, ill figure it out tomorrow. I have a Fan running in there but it really tends to dry out the soil like within 3-4 days. Would their leaves really dry up that bad if it was too hot?

it depends on how hot and if there was poor air circulation. I would be looking at my ph level. also how much nutrient are you using?

those are to big for a one gallon pot. get them in a 4 gallon at least

I only feed them once about 11 days ago with FloraGrow by General hydroponic following the instructions for the "vegetative growth stage" Ill have to get a digital thermometer and a ph testing kit tomorrow I guess.

Never use what the bottle says. use less than half of wat the bottle says. what kind of soil are you in

flush them a couple times

Nitrogen deficiency?

Google around for pics and threads and see if that sounds like your problem.

Just finished flushing. Type of soil is at the beginning of my post; Soil-less Canna Terra Professional Plus.

are you going to transplant into a bigger pot?

It very well could be Nitrogen deficiency seeing as I'v only feed once...?

no not really I barley ever feed my plants while they are in veg. I j ust let the soil do its job. But your container is pretty small so mayby you lacking nitrogen.
