4 weeks, flower?

It'll be 4 weeks tomorrow with this plant. I've topped it once and was wondering if i should flower it yet. No nutes, every 2 day waterings but i spray leaves 5+ times daily, im using a flood light because thats all i got. Let me have any feelings on if i should flowering it yet. Also in the close up picture of the leaves, you'll notice yellow spots, is that from spraying the leaves too much? Thank you

Personally, i wouldnt be flowering that plant quite yet.. but.. what lights are you using to flower with? That flood light wont carry you thru the flowering stage.. also, if you are watering every other day, there's no need to be spraying the leaves too.

since you have the one light only you should start to flower soon. it's time to use nutes.

The only reason i spray it and water it is because the light is so hot and i didnt want the leaves burnt, so i spray them and get the fan on em, but ill take the advice and just water it. the light im using is a 120 watt flood light. i was thinking i would start flowering tomorrow at 4 weeks. if i only use this one light to flower it and plain water only will the plant produce anything? Thanks for the past responses and to any future ones.
