ETHOS - Mandarin Zkittlez F1

Stems are getting top heavy, more weight packed on and they are starting to lean, I don't have room for a scrog net. Pistils are turning amber, only about 10% so far on day one. I hand plucked off the small larfy, sucker buds. I let some go too long and the large majority are worth keeping. Next time I will have the courage to defoliate properly! I get so scared after weeks or months of growing and then removing growth. Final day of week and these colas are stacking on so much weight they are bending over. Noticed nutrient deficiencies and tried to adjust accordingly. Hoping the problem doesn't get exacerbated.
