250W HPS indoor grow- Nutrient Question

Today I gave my plants nutrients for the first time because I started to notice slight yellowing of the bottom leaves the other day. When I got home I looked at them and one of the plants has all its leaves standing straight up! WTF it looks crazy! All of them are pointed to the light. Is this good or bad? Also this particular plant is was topped like 4 days prior. What yall think??
Happy blazin

Plant is happy. All reactions that look "strong" (not limp) are generally good. Might need more light though.

More light generally is good. Newbies tend to use too little.

I have heard the same thing about when they are standing straight up that they are searching for light but idk if this would be the case here. I have the light right on top of them maybe 5 inches away its only a 250w so its not burning them its been good for the new growth I have gotten.
