I've just mixed my very first coco formula for chili peppers. The grow formulation looks like this:
N 207
K 242
P 30
Mg 45
Ca 196
S 63
Fe 5.2
Zn 0.226
B 0.226
Cu 0.063
Mo 0.033
Na 4.5
Si 19
Cl 7.0
Mn 0.50
This includes the salts from my tap, which is pretty soft at 25 ppm Ca. I made 1 litre of concentrate of A:
Yara Calcinit (Ca(NO3)2): 89.92g
Part B looks like this (grams to the right)
Monoammonium Phosphate NH4H2PO4 1.85
Magnesium Sulfate (Epsom) MgSO4.7H2O 13.76
Agsil 16h 7.75
Iron EDDHA FeEDDHA 5.56
Yara Kristalon Plus NPK 8-3-27 83.16
This is IMO a better bloom formula than the other formula you posted. Even this formula looks quite strong. I would lower the N down somewhere between 150-180. I would also increase the P levels to 50ppm.
You say you only mixed this to half strength initially which would of left you with 15ppm P which is very low, young and mature peppers do not differ much in there need for P.
if you adjust your formula to
N - 150-180
P - ~50
K - 200-250
Ca - ~150-200
Then you could start your plants at 2/3rds strength and build up to full. I wouldn't worry about trying to change to a stronger bloom formula, pepper plants aren't that hungry in my experience.
