Can I crank up Lucas formula?

[hank123]

I know the Lucas formula calls for 8ml of micro and 16ml of bloom, I have some large outdoor plants and wanted to know can I crank it up to 10ml micro and 20ml of bloom or even 12ml/24ml?

They are in a heavier soil mix that holds a lot of water so at best I only have to water every 7-10 days in high temps. I would to feed heavy and water well twice before the next feeding.
I feel like I have been underfeeding my other outdoor grows.

I don't use this formula, but in general, larger plants get 'more' food by being in a larger container with more media to put water/food in. Are the plants showing deficiencies, or going light green? If so, then yes, bump the feed!

Not showing any deficiencies. I did give them a half dose of the Lucas formula last week. Watered again 2 days ago. I figured I will give them a full dose and about four or five days. When they are two or three weeks into blue I will start adding liquid kool bloom.

As I stated before I think I started feeding two little too late with my other girls. Every time I have set out doors I've never burn and they always think it well.

I guess I will go with the full strength and see what it gets me

Plants are massive. Five foot in diameter.

I've ran Lucas formula for couple years. Think it lacks N in veg and flower tbh.
I use Maxi grow and bloom and do a 1:1 ratio up until week 6 and drop the grow after that.
Think you would be ok water/feed/water/feed but I'm not outdoors.
Nice looking plants
