last question first : you have run of the mill potassium deficiency (K- deficiency) you can tell from the exterior of the leaves turning first and the coloring happening. Easy to fix that : keep adding PK and the booster, which is just amino acids that help turn the P/K into something the plant can use. Even though you're adding PK you're still seeing deficiencies, so you can up the dose, why? because the plant is so well tuned in that it's growing faster than expected. So now for the first question : this Quick One is gonna become a Fat One in the next 2/3 weeks, i would give her a chance to buff tf up as much as possible, i'm leaning more towards 3 weeks than 2 weeks just for that reason. And for your final question : pretty sure you can expect 70grams dry per plant ! The only way to really tell how she's doing though is to check the trichomes with a 40x + magnifier regularly and try to figure out the pace at which she's ripening up. hope this helps, Chef ! π
