good advice,
plants use more of some nutrients than other's during a feeding cycle (as your ph shifts your plants uptake of certain nutrients changes and if you add a nute solution as your Topoff, you can have toxic levels of some nutes, so adding ph'd ro/distilled water is your best bet...
never tried the lucas formula, but might try it on a couple of clones this go'round...goodluck..just keep it simple for now and you should be successful!
