1-2-1 is as extreme as 15-30-15, it just seems less cause the numbers are smaller but it still only twice as much phosphorus as nitrogen and the same rate of potassium as nitrogen. For me giving the same ammount of nitrogen as potassium in flower and so little phopshorus aswell is a big no no, but some nute lines give you similar ratios to what youre using. Have you seen the PK liquids to fatten buds used in late flower? Well I dont use them because my base for flower has those ratios already with a bit of nitrogen, and the first 3 weeks of bloom I mix with veg.I use what worked for the mother...
24 8 16 divide by 8 = 3 1 2 and
15 30 15 divide by 15 = 1 2 1
Now it doesn't look as extreme.. its just more concentration of NPK per ml or tsp
Now it really becomes more of a matter of PPM... I realized in my first grow I was underfeeding the mother only after finding a long lost ppm meter did I realize the recommended dosage by the manufacture is less than 1/2 what the plant wanted.
last feed (2nd grow) they were only receiving 585 ppm with a RO of 450... I believe they should be getting closer to 900.. i'll have to double check.
I've learned from my last grow.. something you pointed out...and I concur that if majority of the plant looks great not to worry so much.. these had yellow leaves turning brown and dry duing their veg period.. It din't phase me long as the majority was green and healthy.
Example of a typical PK fertilizer to fatten buds, this one is synthetic but there are organics aswell:
Now, if you use that with your base, even if it has high nitrogen the ratios are still gonna be way more P and K than N. Theyre used with suggars to fatten buds. About the PPM I dont know what to say, its been so long since I used one PPM meter that I cant give you an opinion on that.

Exactly, as long as its just a few leaves with minor signs its just the plant telling you what she likes and what she doesnt like, its totally fine. 1 leaf with nitrogen toxocity is nothing, it will still perform, the problem would be if all the plant had excess nitrogen, not just one leaf, then everything would get out of control because the ratio of nutes is umbalanced and theyre blocking each other causing other major deficiencies.
