1. Forget the big bloom instructions, it is too strong. You can do what you want, but you said yourself you increased the dosage from what they liked before, and now there are problems. The only way to really tell is to cut out all nutrients, flush with clean water, start over at low strength and work up from there. Less = More.
2. If you are watering every other day, or even every 2 days, that is watering too often IMO. A plant that size in that plastic pot (not fabric pot), if watered until the pot is soaked with 20% runoff water, will not dry out in 2 days. It should take at least 3-4 days. If you water every 2 days, the pot will not dry out and the roots will not get enough oxygen. For cannabis plants, the roots need oxygen as much as the leaves need light and CO2, that is why the method of watering is so critical to overall plant health, harvest quality and yield.
The proper method for watering is to soak the pot and let it dry out, and I mean dry, like almost saraha desert dry, right before they droop. I use a scale to be sure I have enough patience and force myself to wait until the pot dries out. Sometimes, this means I wait an extra day waiting to water compared to if I just guessed when they need water. I am terrible at estimating the weight by picking the pot up, especially when the difference is just 25 or 50 grams, not very much weight but the difference between watering now and waiting another day.
