Local water report

Tap water as no nutes needed as of yet . I got some magnesium in diluted to recommend and defffo helped leaf curl but I will have to lime to see calcium response see if I can get shut of yellow/rusty looking parts expanding on newer leaves. Please advise

Nope I'm wanting to do my wiring in series but really fighting with elg-100-1050b and 1400b. External dimming I think will be easier to control . It's a straight forward 2 cob light clu048-1212 to wire in series and the best driver to do so?

Thanks Moflo, that's a great grid of reference and makes it easier to clarify figures instead of notes written on envelopes and cross reference pages by screen. But I'm now thinking the 100-1050b is best with a 100k pot to dim. I hope for a little more advice on this as efficiency if any more...
