Lucas Formula and Method(s): Step by Step

Was that ment to me pip313? If so I didn't understand anything.

Take a small cup and get a sample of your mix. Add a couple drops 35% h2o2

I don't think you need to but if you want clear nutes h2o2 will do it.

The FNB used as Lucas before the buffer was removed

This is an old label I posted on a completed grow thread, on another forum. Mixed Hydro - Coco/perlite .. FNB feed as ppm, starting low and raising the PPM.. The 3% citric, that was removed, dropped my ph a full point when mixed.

Promotes Vigorous Flowering & Fruitset.
• Superb for Hydroponic and Soil Cultivation
• Super Concentrated & pH stabilized
• Outstanding for all kinds of plants
• Use for flowering and fruiting phase
FloraNova represents a breakthrough in fertilizer technology.
Combining the strength of a dry concentrate & consistency of a
liquid. This unique formulation of highly purified minerals, plus
natural additives combine the best of both the hydroponic and
natural gardening methods.
All elements required for hydroponic cultivation are combined
together in this unique one part formulation.
FloraNova is extremely concentrated. A very small amount of
FloraNova mixed with fresh water will provide your plants with
proper nutrition. For hydroponics, soilless mixtures, potted plants in
soil or for your garden grown plants.
Use for all types of plants from early flowering through harvest.
For Best Results:
• Use a conductivity or ppm meter to monitor water quality
and control nutrient strength. Drain, discard and replace
nutrient every week or two to prevent nutrient imbalance.
• Maintain nutrient pH between 5.0 and 6.5. Adjustment may
be necessary since water quality and pH vary both regionally
and seasonally.

Have been thinking of adding 3% citric back to a new qt bottle of FnB that's missing it.. I'm afraid it might cause certain parts to precipitate out. Would hate to waste 25$. Any opines on this?
