Royal Dwarf - First Grow (Indoor)

Ive been battling yellow tips and leaves dying from the bottom up for a few weeks now, I thought I gave them too much nutrients and started feeding less and flushed them a few days ago. I thought I had a nitrogen deficiency because of a nute lock, well turns out in reality I gave them too little nutrients and just made everything worse with feeding less and flushing, bruh. I have a Potassium (K) deficiency, I will from now on feed using the BioBizz feeding schedule and hope my Dwarfs will be good. I already simulated a little bit of morning rain using the BioBizz schedule, about 400ml, just so the upper root mesh can already pick up some Potassium (K). The bud development is also going quicker now over the last days, I feel like my dwarfs are a bit behind on buds because of the deficiency and me not realizing which one it was. Picture 1 - Day 43 - Topped the two smaller pearls. Dwarfs going ok. Picture 2 - Day 43 - Dwarf 1 is 90cm now, I dont know why since the advertised height is 60cm, Im not mad tho hopefully it just means more buds. 😁 Picture 3 - Day 43 - Dwarf 2.1 is 68cm now, he got a huge boost since he went into flower and I started feeding more, his buds are also getting thicker now. Picture 4 - Day 44 - Dwarf 1s buds are slowly but surely getting frosty. Theyre also getting pretty huge now, yay! Picture 5 - Day 47 - Potassium deficiency keeps getting worse on both plants. I fed them a lot of nutrients again todays I hope itll help. Picture 5 - Day 47 - Buds looking ok, kind of tiny still for 7 weeks. Picture 6 - Day 47 - Dwarf 2.1 seems to be hit harder by the deficiency.
