Is 500 watt MH to much light for 2x4x5 tent

I’m having problems with my plants in veg. I have 1000 watt ballast with 1000 watt bulb dimmed to 500 watts is that overkill. My plants growth seems to be stunted I also switched from using coco w perlite mix to sunshine # 4 and I’m not sure whether it’s a heat or light or nutrient issue pls help

I tried the flora nova veg sample that I have also maybe I dint shake the bottle enough??? If I flush these with the sunshine 4 am I going to cause more damage to the plants?? My lights are off but I will post pics at 11 30

If your temps are ok then its not gonna hurt anything. yes its overkill but thats the point , right? we would need to know more details. size ,age, pot size ect....
Only 5 foot high ? i dont know ....that is for sure overkill. maybe even too much. If they are big enough then more food would help but not without knowing more details.

Okay I have one Tangie I just transplanted from one gallon to 3 gallon the rest are in one gallon pots. They are 12 inches tall I’m using sunshine 4 I’ve never used before with GH Armor Si flora Nova grow and Diamond Nectar day 22 veg I started w cuts not seed last feeding was yesterday 307 ppm Ph 6.05 I also use max microbe. I’m thinking about scraping the Nova and going with the florA trio which I’m more familiar with. If I flush these plants with this sunshine # 4 which I don’t think gets hood drainage at all am I going to make the problem worse. Lights on at 1130 I will def post pics at that time thx for responding so quickly man I appreciate it

Okay the one I’m concerned about is in the 3 gal it’s tangie cut the one to the left is lime og . I took pic of the tangie and I believe there rust spots from overwatering. I have them under cheap blurple light right now so there at day 21 last feeding last night 302 ppm ph 6.05 . I’m using sunshine 4 and I’m starting to think that this is a heat issue and an overwatering issue as well. I have 6 inch hydro farm inline fan just blowing out of the tent so temps are staying around 76 to 82 which is to high. I’m going to introduce Honeywell fan and slap it right underneath the light facing up with humidifier in there as well. Crank up the ac and see if I can’t get stable temps in there. My veg setup sucks.I would also like to flush or at least get a less potent solution in there but I am worried about water logging and root rot at this point. Also I was thinking about just biting the bullet and buying LED for veg but I know nothing about them and don’t want to make a bad purchase and just adding to the problem. I was looking at a viparspectra 300 UL certified but am concerned about the heat an the light intensity. What do u think ? Any recommendations or ideas from any one would be great and definitely appreciated thx for reading this really long message. Whew I feel like I just got done writing a book lol

"Flushing" is a waste of time. Yes you are correct , it will rot the roots. your just going to have to let them dry out longer and feed a lil less if the light is weak. 76-82 is close to perfect sir. Not too high at all.
