leaves and flowers status

Best to understand what's happening is leave the first grow with next to nothing nutes or push slightly and then move feed up 1 by 1and you will get a feel for what she wants you will get the feel for it mate.. Happy farming

You're only in your 2nd week of flower, you don't want to start giving a bunch of bloom nutrients yet. The first 3 weeks after you start to flower are a transition period and still going through a bunch of vegetative growth. I increase my veg nutes just a little and start adding small doses of bloom nutes, after those 3 weeks I then start slowly lowering grow nutrients and start increasing bloom nutes. I don't think it's the trichomes you're seeing turning colors, not this early but some of the pistils (white hairs) will start to turn. You will need a jewelers loupe or a microscope to see the trichomes clearly but you have quite a bit of time until you need to start checking them.

too early to look at trichomes the reddish stuff in leaves is probably due to cold temperatures at night (anythign near 68f andbelow can do it) as far as the imbalance.. hard to say from a few pictures. need more info. skinny blades might be genetics or too much p/k. not forming the typical 3-5-7-9+ progression might be genetics too or a poor formula in general preventing the natural progression. if soilless, a ppm breakdown of the nutes would likely cast a spotlight on any problem. if soil it's always a crapshoot of uknown variables you have to guess about.
