I got done with my temporary soil grow and have moved on to DTW in Coco.
I've got 2 plants that were my test subjects as I got everything dialed in.

had some issues with what EC to run and how often to feed. think all that has been fixed. running EC at 1.2 (nutes 1.0 and water 0.2) and started feeding 15seconds/hr and now they are at 25 secs/hr.
Here's 2 seeds that I started 8/10, they popped 8/13 and are now trying to get bigger and badder. They are SuperSkunk from Nirvana seeds.
There is a modified lucas formula for coco called h3ad's (I think), it's listed in the lucas site. Not sure what the EC is one that and it's a HUGE thread to read with several people disagreeing exactly what the right formula is now but it's worth the time...
YMMV...

Yeah, I did find that h3ad formula: it was like 6/9 plus calmag
I started with house&garden coco a/b but I had some issues. I gave it a few weeks but I just switched over about a week ago to Lucas. stick with what I know works at least for this first grow. I do like the drain to waste. I set the pH in the res once and a week later it's still good to go. Just dialing in how long to run the drip halos per hour is a bit tricky. It seems like I get just a bit of run-off every feeding which is what I think is supposed to happen.
Yeah, he later says he dropped the calmag because he switched to well/tap and other people argued about using it (or not) and how much waste/how often. I still don't know what the current coco formula is. Maybe it'll be the RKY formula...

this page is an an interesting read for anybody interested. a history of Lucas formula and a pretty cool nute calculator to see how other nutes match up.
Nice share, I think I've linked that calc before but things get buried on forums so it's good to reshare things like that on occasion.
I use that calculator when checking new nutrient mixes to see if it has enough of the major stuff. The 100-100-200-60 "rule" doesn't take micro nutrients into consideration so it's really more of a guideline and, as we know, different genetics, environmental conditions and lighting situations make a difference too. I like lucas (for hydro) because it's simple and they can use it for veg and flower...once they get it dialed in for each situation.
