I mean you could use that old light you have and pop it in a wardrobe for some vegging.
Say you set the schedule so you have a new plant start on the old light in a wardrobe, then move it into the tent with the big light when it comes on during the day? So you’ll have one making its way while one is in flower
The evo light in my main tent is on an odd schedule currently, i have it turn on at 6pm and turn off 12pm cst. So I would have the one start in my smaller tent I have with my old light then once this one is done flowering I would move the one starting out into my main tent? or move the one back and forth? i do have that second smaller ac infinity tent but i unfortunately only have the light that i could put in there, all the other internals are in my main tent.
You could veg a healthy plant by itself in a wardrobe on an 18-6 schedule with little extra gear.
Explain your current light schedule, you said its on for 6 hours, then what?
Edit* sorry just figured out thats 18 hours lol.
You can do this.
Give the new plant the 12 hours of the 300 watt with the old one. Then make up the remaining 6 hours under the 100watt
That old kit is for vegging 
@Dinky
I see what youre saying! I might have to go ahead and go through with this! Otherwise, Im still considering picking up some more auto seeds, or do you think I should try out one of the photoperiods?
Also here is how she’s looking today! I hope your seedlings are going well!!
Sorry go ahead with what?
Looking better
The leaves that are totally brown with no green left go ahead an pluck those
Oh sorry, I shouldve been more specific when I said that! I meant Ill most likely go ahead and setup my other tent then start germinating another seed to grow like you were recommending before.
Also, I woke up this morning to some pretty turned down tips -
For now dude all we can do is wait until she’s dry and get that next run off, keep in mind a lot of your leaves are already affected and your gonna have many burnt tips that will crisp up. She’s in the middle of branching out a bit and you’ll have some new foilage from that and with the stretch in flower
Okay, I understand! I was just a little worried about her! Once she goes dry, I’ll make sure to water well and most importantly grab that runoff!
What up @jeremyg how’s she lookin? Must be today or tomorrow for next feed or is she still damp?
I hope you’ve been well! She seems a little upset, today she just started laying the leaves down a bit and the curlings still there but hasnt gotten worse. It seems like its pretty much ready, I was guessing I’d either feed today or tomorrow!
Yup feed time
So however long that was from the last feed. Minus one day, and thats how often you should be watering her
Alright! I did the flush and fed on Oct. 3rd so about every 4 days she’ll need to be watered! Should I water with just purified water no nutes until runnoff or feed with my big bloom and grow big?
Straight in with your water ppm’d to 800 lets see what comes out 
Im about to feed right now! Fingers crossed the run off is good!!
I just got done with feeding her a gallon! The ph seems to have gotten better as well!
This is how she looked just after the feed!
Thats good about the ph! And the reason why we went with 800ppm again was just incase of that, the ppms climbed again!
So next feed same again until those numbers start coming down.
It usually takes 30 mins for the water dance 
Side mission: Anything that looks like this try and expose to as much of the light as possible.
I see there’s no holes in your fabric pot, you can get a clothes button hole puncher pretty cheap in most hardwares. Or alternatively just tie a piece of fishing line to a clothes peg and peg it onto the pot. I want ya to take that little branch and tie it down slightly so its almost horizontal. A little branch like that will be perfect practice, go easy and slowly.
Those little shrivelled up leaves at the base of your stem pluck them off and tidy up any dead leaves on the surface of your soil - mould hotspots!
