Every strain is different. Idk after a while the plant "tells" you what it needs the first time around. Then the feeding for that strain becomes second nature. I'm not going to bore you with MORE plant pics for examples. But there is a BIG difference between the first Pineapple Muffin I did and the two that came after it. I've been growing White Widow forever. It's like my danky stanky staple must have a gallon jar of those buds at all times or life ends. It definitely has its unique needs. I don't think there is really a one size fits all nute approach that works. I mix different formulas and have different schedules for all of it. Tons of them have a lot in common, but for a plant to be the best it can be? It's not always the same. My big widow that I'm working on now has the main cola at over a foot long and it is filling in VERY nicely. It's getting DELUGED with cal mag. But that's because it is in a 5 gallon grow bag instead of a 10 gallon. Soil is depleted. And it's WAAAAAAAAY too late to rebag her. So that dirt is more like coco fiber at this point with absolutely no viable nute value. The Pineapple Muffin plants were supposed to be TALL. Yeah bullshit. I've got two 2.5 ft tall indicas that a) auto flowered when they shouldn't have. b) are in 5 gallon bags too BUT their soil is solid. c) weren't topped because of the supposed height I was going to get out of them. I was looking for 4 feet. So the way they are fed is MUCH different than what the widow is getting. But the first PM? Hah! That thing is topped, trained, and just started flowering. But the soil in that bag is probably 50% to 60% as that plant has been vegging for 12 weeks now. So even though it is Pineapple Muffin, its nutrient needs are much different than the single cola, younger PMs. I guess what I'm trying to say is they are ALL different and there are fluctuations within the strain depending on its environment, soil, light.
