Noob Trichome Help

For subsequent grows (even for plants finishing now), I have to tell you "all purpose" nutrients are GARBAGE in flower, particularly. For specifically potassium and phosphorus (main concern in flowering is phosphorus) you can get MKP (mono potassium phosphate) for really cheap. It would complement your all purpose nutrients well. So then you'd use a bit of that with your all purpose nutrients when prepping your soil, for roots, early veg. Use your all purpose nutrients as you would/did, until preflowers, and then start lowering those all purpose nutrients, while adding MKP and keep on gradually biasing towards the MKP and less all purpose nutrients more into flower. Also, there are some variations in MKP, some is a bit more biased to potassium, others more towards phosphorus, personally I would use the MKP more biased to phosphorus, like 52 phosphorus, 34 potassium. A bit of extra calcium along with that is usually a good idea too. Simple stuff.

Hell no. 2-3 weeks. Your plant pistil development is a better indicator of maturity than early trichomes (unless you had really messed up growth, like your one plant with nitro excess with messed up inconsistent pistils and super dark green leaves), and your plant says it's not there. So yeah, for future reference, lay off the nitro. And I really hope you're not actually using 24 hour lighting, that's not very bright.

Definitely clear. Wait a week and get some more shots and you'll most likely see the milky Trichomes you want. This stage is always difficult because it's exciting and you want to harvest to enjoy your hard work. Panteince is key.

Nice pics. Looks still mostly clear from what these old eyes can see..

Got a bit to go yet, those are mainly clear looking. Keep an eye on her but she needs more time to give you as much as she can. Also any other shots that aren't of the pistols
