Nutrient Help

Hi All, Newbie with first post here so pls forgive any rokie mistake regarding posting. Thanks.

I have a problem. My first grow was durban poison and Maui and African power. The Durban and the Mai suffered terrible throughout from lack of calcium despite my best efforts.( growing in RDWC using Fox farm nutrients). I have been flowering for 12 weeks with very little buds but the African Power seems to have done better.

I now have 2 clones growing using Flora Nova and the Lucas formula and all seems fine but for the cost of R/O water. To reduce cost, I am thinking i should move to FloraMicro for hard water but my hard water PPM is already in the 750 range at 7 conversion.

Will this work and do i continue to use FloraNova or switch to the flora 3 part series?

Any ideas?

Thanks all.

Are you sure your ph was 6 for the previous grow?

Since your going to use tap with that ppm, you are going have to dilute the lucas strength (it's for r/o water). Also lighting wattage effects the strength you use as well as plant stage.

Remember the saying "It's better to under nute than to over nute".
