cow manure,bat guano,worm casting??

my plants is not taking off like I wanted to I had it under my T5 light for like 5 weeks and now it's been like a month in the ground they were stress out and had some problem but now it looks better but it's taking too long to grow. i'm using top soil on the bottom and roots organics 707 on top in 2 feet deep 2 feet wide holes and I was wondering is it too late to add like cow manure,worm casting or bat guano. I don't know which three of these to choose from and will it help my plant to grow better and will it burn my plants if i just put some of these manures on top of my soil? so please let me know which one is better and how do I use it since my plants are already in the ground.

I would suggest some good old Steer Manure, actually "Gardner and Bloome's" Farmyard Blend, if you can get it! Farmyard blend is just what it sounds like, a variety of farmyard manures blended together - it's really good shit!

Manure is fairly balanced (NPK-wise), plus, it is cheap and "strong" enough to do some good. Worm castings are also fairly balanced, but may not be potent enough to be added (after the fact) for a "rescue mission". Bat Guano, on the other hand is plenty potent, but it's not at all balanced. Guano either comes as a "High-N" variety, or a "High-P" variety. So if you do use Bat Guano - you'd better know what you're doing!

Whatever you decide to use, you can "Top Dress" it in. Just sprinkle the desired amount on the ground surface, about the size of the "drip line". Then just "scratch it in" a couple of inches, or so.

I bought a bag of bat guano with the high nitrogen and I put it on top of my soil and gave it 2 gallons of pure water so hopefully it will help the grow. Where I live is over 100 degrees this last week and will continue to stay in the high 90s or over 100's the whole week.
