I was pushing nutes every feed when mine started too. But my one plant is completely uneffected. It eats anything I throw at it. Same strain. Same batch of seeds same exact lighting and feeds
Yea same I have 2 uneffected plants, seeds aren't the same though even on the same strain. Seeds have a lot variety (gets more stable through around F4 or F5s) other than that expect diff growth rates, feed rates, some seeds lean towards different strains inside the crosses.
Sure you'll find some of the same phenos time to time but there is a lot of variety in there.
