I plan on using the Lucas formula for flowering but have heard alot of controversy over using it in veg?? Any recommendations from people that have vegged with the Lucas formula???

I've used it in veg with absolutely NO problems. Plants were nice and green and grew as vigorously as when I use the whole GH flora series. I use tap water and grow in coco, btw, but have used Lucas in waterfarms:)
 
It will work but I remember Lucas himself saying that he had better results with 1-1-1 in veg when vegging longer. Lucas I believe was originally intended for short veg periods.

I just vegged 6 weeks using Lucas only adding CalMag. I had explosive healthy growth, no troubles @ .9EC I don't see any problems with long veg via Lucas... Go for it, check out my 1k vert thread to see a long Lucas veg...

Note that Lucas lists numbers as Grow-Micro-Bloom. Thus his 0-8-16 or 0:1:2. The veg formula would be 0:1:1 (still no Grow, it's useless and throws off the NPK proportions) Start at 0-5-5, monitor EC and pH readings and adjust up or down from there.

Yuuupp. His newest incarnation actually starts with Floranova grow at whatever the ratio is 6ml/gal maybe (i use 3 part so im not sure) and then all add backs are with floranova bloom..

yep, id get flora nova bloom though, ive been using from day one. of course i add a little extra for my own preference but i pretty much stick to the formula.

works well but i would still watch your plants through flowering as some have had issues with it being too much nitrogen, which lucas formula focuses on, if anything just drop the doses a little as i noticed some strains prefer a tad bit less nitrogen.

also if you are new to the formula and dont really know what you should start adding per gallon for veg versus flowering, start out with 5ml of nova bloom per gallon during veg and then go to 8ml per gallon in flowering.

he has a new formula that starts with nova grow? i cant find it... where?

i dont know if this is true because nova grow is almost exactly the same as nova bloom, would seem pointless to use both for cannabis at least.

same here, I use lucas with FNB from rooted clone to harvest, with about 12 strains no problems, save having to supplement with cal/mag for hungry strains using R/O.

Your problems probably have more to with your little extra for your own preference than the formula...

On the Canna-World Ask Lucas thread, which apparently doesn't work anymore..

And yes it is 100% true.

And OP, Mel Franks targets, which is the principle that Lucas formula is founded on, uses a different ratio for veg than flower.

I use from veg through flower as well. In veg, if I see them getting a little too stretchy, I cut back on the micro a bit and add more bloom to cover the ratio. I cut the micro a little early in bloom this run, so my ladies got a little more yellow that I would have liked. Added more micro and they were much happier again.

I used it for a 21 day veg in a 0-x-2x ratio with good results using moderately hard tap (EC 450, pH 6.8).
It is by far the easiest and cheapest nute regimen I've used.
Highly recommended.

I did not know that. I always thought that he reccomended 1:1:1 (G-M-B) for longer veg. This is the first I've heard of 0:1:1 for veg. I generally veg with G-M-B @ 1:1:1 and flower with Lucas @ 0:1:2.
