Any recommendations for additional nutrients? Neve...

She looks very nice the way she is. you got some Blooming Fertilser whith More P+K that she needs now. like dude said take some Blackstrap molasses 1-2 tsp in 1 Gallon water . she would like the sweet treat. and for sdiagnosing any defiencys are pictures without hid- LIght the solution. Happy growing

She’s looking beautiful already, you really don’t need much, if anything in my opinion. Cal-mag can definitely help with bud density and is worth using. But you may also want to try some Bud Candy to increase the flavors. Molasses’s may be worth trying also - some swear by it, but personally I was not too impressed (its cheap though). good luck. 👍

Yeah cal mag is a good one to use, but it doesn't get absorbed by the plant very quickly, so it could be tricky at this stage. Mag Sulfur is a good option for flowering stage because the plants use sulfur to make flowers. I noticed a flower boost + P/K works really well, especially if you want to make a ton of frost. you can also use mollasses, that's bio and really cheap. Seems like your plants have a deficiency of something starting ... so i would assure that the base nutrients are there NPK. Good luck, it already looks very promising !
