When should I start my Lotus Bloom Nutrients?

they look fine i wouldnt add anymore nutes atm and you switch to bloom nutes when its time for bloom. cannabis plant uses a shit ton of nitrogen during all phases of growth but especially during early bloom when it flips from vegging to flowering. it stretches excessively at that phase and all that newly created plant tissue needs nitrogen to be created. at this point during stretch you can slowly start adding bloom nutes and after the stretch you can very slowly dial down your grow nutes but dont cut them out completely because flower tissue is plant tissue as well and it needs nitrogen. also just an observation: you got too much direct wind on your plants and thats gonna give you windburn in flowering especially. you want a breeze around the canopy not wind hitting the canopy.
