Should I keep both just veg switch on to hold my clones until they go outdoors or should I flip both veg and bloom?

you should use whatever provides the most DLI the plants can handle -- if you want to maximize growth. 100w and very likely not an efficient light producer, so maybe 30watts per sq ft will do it with that light on a 18/6 light cycle. So, depending on hanging distance and the area you are covering.. if it's 4sq ft, you want the full thing on for 18h. .. observe and react to plant growth. The resulting length of stem that develops over time between 2 internodes is your guide. too tight = need less. too long= need more. the effects of red and blue are real and measurable against a control group, however, these effects are fairly small effects. Total light applied is by far more important. Read up on Daily Light Integral (DLI) on wiki is fine.. lots of decent sources for that one... the gist is fine, you don't need to memorize the math.. but puts applying light to a plant in proper perspective.. i.e. it is about photons received per day.. not too little and not too much - the whole observing the internode development above helps fine-tune this. hours of operation are 1:1 related to resulting DLI, all other factors remaining the same. Increasing rate of photon/s applied is 1:1 directly related to resulting DLI, all other factors remaining the same. e.g. going from 18h to 16 h, while at same power and hanging distance drops DLI 1/9th. As long as you give enough light to avoid flower, this is a valid option to impact how much light you give per day... just as effective as a dimmer knob or using veg or bloom switch on its own etc. sso the answer is it depends... if not trying to maximize growth between now and moving it outside, i'd just give it enough so that the plant doesn't stretch too much.. obsererve and react.

I;d do both, just make sure its not to close. more light = more energy = more growth... in most cases unless it to much and and it can equal less growth. Best to find a PPFD map for the light and go off of it. or if no light meter base it off of new growth on the plant. little to no space bwteen nodes. to much. to much spaceing to little, some space, good ammount.

Blue light shortens internodal spacing, red light promotes longer internodal spacing. Has nothing to do with leaf shape or size that is dictated more by light intensity and the distance from light source , the plant creates bigger leaves when there is less light available in order to catch more of the scarce photons passing through the chloryphyll. Long thin leaves are a sign of high light intensity. Preferably you want to use higher levels of blue, keeping the plant as compact as you can prior to stretch. Won't hurt if have red on too, if it's going outside too then I wouldn't t worry so much so long as she is healthy. Blue photons hold almost 2x the energy of red, excess blue also promotes stomatal widening allowing greater uptake of co2. Blue is the primary wavelength for chloryphyll production as it is easiest to absorb.

Blue light/veg side on alone will keep plants shorter with smaller leaves. Red/will make taller with bigger leaves for taking up energy. It depends what you want really. I would personally turn on both so that it’s receiving everything. Full spectrums the way to go imo. Good luck in whatever you decide & with your grow
