I dig your naming scheme! I just used Aa, Ab and Ac...., but numbers are better because then you're not limited to 26.....
Not in tubs, in coir & soil, absolutely. I've observed often huge differences in nutrient requirements. EG Cali Blue (Cali O x Blueberry) was only requiring about half the total nutrients as another line I was running at the same time called Mother of Thor (can't recall the lineage, but she was so good! past tense, cut's been lost forever), who isn't exactly a nute hog in the first place. Where 2ml/gal of Floranova Bloom would burn the Cali Blue, the MoT was begging for more.well looks like i have another issue.
P1 and P2 seem just fine and of the same pheno type.
P3 which seems to have thinner, longer leaves (and of a different pheno) has nute burn issues, while the others don't.
has anyone experienced 1 plant in a tub with nute burn and the other two don't.
350ppm, 6.15ph...
i am working on a water/nute replacement in my tub now...
Couldn't part of the spectrum of phenotypical differences include feeding? I think it can. Just like kids, right? My sisters have never battled their weight, I've battled it all my life.
