I consider this the 5th week, which I'm treating as the 1st week of flowering since they still resembled veg plants in week 4. Now in week 5 (although it looks more like week 6), I've noticed some salt build-up, and within just a couple of days, signs of "nutrient burn" have appeared with leaf tips showing burns. I've already performed some flushing and defoliation by removing the affected leaves, amounting to 60% so far. I'm contemplating whether I should remove the remaining affected leaves, even the smaller ones. I understand it might shock the plants, but I'm keen on observing. I'm also considering top dressing, but I might hold off until the next watering to gauge their response after the recent flushing.
