We ran straight Lucas for over a year. It works but Latewoods modified is better. There's a sticky for it.

5th week of flower and your mix would be

0ml's per gallon (grow)
8ml's per gallon (micro)
16ml's per gallon (bloom)

I would read the label for koolbloom and the hydroplex it maybe too late in flower to use or it maybe like gavity and need to go in now on week 5.
LOC NAR on probation Reviewed by LOC NAR on probation on . Lucas GH Schedule with *New* Botanicare Hydroplex?? So I've been using the GH 'Flora' series nutrient schedule. I've been following the feeding schedule thats printed on the backside of the container, ( i was just trying to keep it simple) (Grow-1 tspn/gal...Micro-2 tspn/gal....Bloom-3 tspn/gal). Tap waters not too bad here so Im using that, and also saving the trouble of adding cal/mag. I started with rooted clones, vegged for 5 days, and now in the 5th week of flowering. So far everythings been great, and I haven't had any problems. Rating: 5
