GH Flora Trio feeding strengths

Hey guys. So I've noticed that the feeding schedule on the bottle for the standard Flora Trio is obviously a bit too intense for cannabis. I was wondering if there's any chart or feeding schedule that anyone has followed that provided great results. I'm familiar with Lucas Formula, what is the full strength PPM of that ratio (8micro/16bloom per gal)?

Not too intense; you must adjust. Use 25% from start then 50% and so on. Average around 6-800 for adult veg plants, 1000 - 1100ppm for adult flowering plants, heavy feeders 1400+ppm in soil, good luck

So mixing exactly 8ml of micro and 16ml of bloom to every gallon of water would equate to roughly 1000ppm? So I'm correct in assuming that 25% strength = 250ppm and 50% = 500ppm etc.?

No my bad I deleted because I didn't see this was in the hydroponic Forum sorry, please forget everything I said I am soil grower

Ah, no problem man. I just don't personally have enough nutes to just waste in order to check the ppm at different ratios. Hence why I figured I'd just ask what the full strength ppm is so I can make adjustments based on that.

Yeah, full strength Lucas would be close to 1000 ppm. I use the 5/10 for my light feeders to get around 6-700 ppm. I put my clones right in the 5/10.

What are you growing in. If its water the more you aerate the less nutes you can run.
Half everything on this chart and start there.
I run 600-650 in full flower, start at 100. On a 500 scale.

Don't run lucas especially not in veg. Notice that you taper off a lucas type ratio near the end.
Lots of people go good with it but I had nothing but trouble trying to run it.
You are right about the ratios but the cool thing is you run 1:1:1 most of the way through.

Yes.... This gives you room for the 6 add ons. Since the OP is in soil feed feed water.

I'm growing DWC. So you recommend using that chart but halving everything? So ie. Week 1 : 1/8 tsp of Gro, Micro and Bloom instead of 1/4 and so on?

I'm still adjusting to the recirculating nutrient film thing, how much is a good amount of water per plant in the reservoir????

I bought a 55 gal tote yesterday, as now that the plants are big they make the water dip very fast in the one I vegged them with.

I only filled it halfway, which is still about twice what the previous res held. The old one is back on veg duty with the baby plants.

1:1:1 mix and dilute.
.6 ec seedlings
1.0 veg
1.2 1.4 flower.

Yup. Since your in DWC you can probably run a shade stronger but still start low because underfeeding is wayyy easier to fix than burning them. You start low and work your way up to what the plants want. The best way to do this is by watching PPM's. You need a PH and PPM meter if ya don't got them already.

Also, it is funny because the chart says calmag is "optional". In my world calmag is a must have. No-Go without it.

Depending on size of plants. 6 footers drink 2 gallons daily each. 55 gallon tote should last ya a week or 2.

I got 5 3-footers in there... most of the bottom is lollipopped..

Do you mind telling me what PPM's you got for each week of that chart? Or at least one of the weeks? So what PPM would 1/4 + 1/4 + 1/4 amount to?
