I've never followed those feeding charts at all, I just feed based on how the plant is looking, every plant will have different feeding requirements. I use AN Sensi Bloom, 4ml/L is full strength and I don't ever recall giving any of my plants 4ml/L
Pot looks a bit small you may want to think about transplanting, when you say you fed 2ml/L of AN is that 1/2 strength? it sounds like it's a bit early to be feeding 1/2 strength nutes to a plant that size
Not really, not to me, I usually think it looks like more spotty than the above - yours looks like something else like maybe ph fluctuations

yeah I may have stopped feeding it a week or so too soon - have to say this plant was a really light feeder, not sure what the hell it was living on lol
looks like classic K def
not sure what the correct ph is for soiless but yours seems too high
also could be feeding too little K or K is getting locked out by overfeeding of something else, too much Ca for example would lock out K
Oscillating fans are good as it's not a continuous air movement on any 1 bud, I have 1 osc fan and another stationary fan to hit any buds that are too close to the osc fan, mold is a real bitch have a lost plenty of buds in the past due to it :(
thank you - most of my previous plants i let go probably too long and they feel a bit sleepy/couchy - i think i will just chop this and see what the effect is like, there are 1 or 2 amber trichs now but not even 5% in my estimation
not lighting I don't think, look at the edges and the tips, early stage K def, maybe caused by a lockout as they seem green enough to indicate they are getting enough food
