you can actually grow with those lights from start to finish and you would get some yield out of it. The lights aren't causing the droop. It's something else and to me at a first glance the soil looks really dry.

Give them some Water ph'd between 6.3-6.8 if that is a soil grow.

bluish lights are great for creating compact vegetative growth. Red lights I believe make plants stretch slightly and is ideal for flowering.

but either light can actually be used for either stage of growth. It's just one is more ideal than the other.

Hope that made sense.. still stoned. LOL
