High priority changes/bug fixes:
- Phosphate in Fleet corrected to 131.36 mg/ml from 669
- "Calculate" button no longer clears value entered in the phosphate amount box
- Flourish macro ferts (Nitrogen, Phosphate, Potassium) no longer report iron
- On the "Find amount of target chemical ... " page, corrected the 'Grams or milliliters to use' value when selecting a liquid fertilizer. It was off by a factor of 100.
- On the same page, 'PO4 in K2HPO4' was showing results for K instead of PO4. Fixed it (although admittedly, the K value was not far off from the PO4 value).
- TSP-to-grams conversion factors (used in calculations) changed, based on these values:
MgSO4.7H2O : 5.10 g/tsp (from 4.00 g/tsp)
Miller Microplex : 3.90 g/tsp (from 'TE Mix' 2.60 g/tsp)
CSM+B : 4.30 g/tsp (from 'TE Mix' 2.60 g/tsp) - Updated values in the "Conversion of tbs / tsp / Dash / ..." table to reflect the actual conversion factors used in calculations. This includes fixing the typo for MgSO4.7H2O (now 5.10 g/TSP instead of 14.00), and also replacing 'TE Mix' with separate entries for Miller Microplex and CSM + B.
Lesser priority and/or 'usability' changes:
- Changed the number of items displayed in the drop-down boxes on the "Get concentrations from chemicals added" page to allow all possible sources to be displayed at once. 'Iron Fe' sized to not go beyond the bottom of the Fertilator application.
- Removed leading zeroes from TSP values in the "Conversion of tbs / tsp / ..." table to improve readability. (With the MgSO4 typo corrected, they were no longer needed for alignment.)
- (Really minor) corrected spellings in some places
New Fertilizer Support:
- Seachem Equilibrium -- selectable as source of K, Ca, Mg, or Fe
- Tropica Plant Nutrition Liquid (formerly known as Tropica Master Grow or TMG) -- reports K, Mg, Fe, but only selectable as a source of Fe. Concentrations of other elements too low to justify selecting it as a major source for those elements. (Getting to recommended concentrations would add much too much Fe and other micros.)
- Tropica Plant Nutrition+ Liquid -- reports all but Ca (none contained), selectable as a source of NO3, PO4, and Fe.
