How much ppm's do you feed in flower?

To anyone who may have been following my threads in the last couple weeks knows i've been having deficiency issues. I just measured my ppm's for the first time, to realize that I've only been feeding about 250 ppm of food in flower. I think the poor girls are starving? 1.5 mL per gallon of DG. Guess Im going to have to step it up. The drain to waste feed chart recommended by DG says 5 mL per gallon, or about 800 ppm. which sounds a bit much. Maybe I should step it up to 500ish?

In full flower you can do 800 no problem... That's 1 tsp per gallon... Don't forget the calmag.

800 ppms is not a lot, I feed with DG at that every time I water

My feeds in a galon bottle look like 780ppms then end up being 1500 at the bottom of the bottle, even though i shake it up a lot.
Plants arent looking too overnuted though, some minor tip nute burn.

Lucas formula is like 1400 ppms in veg and bloom lol

I start at 1000 for a new strain and then adjust to what the plants tell me from there. If I get any tip burn I go down to 850. If they look like they need more up to 1200. Keep records and then start with the adjusted level for that strain next round. Rinse and repeat.

it all depends on the root mass .......i had a plant up in the 4500 range

fallow the plan and step it up to what it saids if u see a bad reaction lower to 600ppms add in some destresser wait untill they get use to it then bumb it up until u see the burn on the tips and then cut it back 10% hold there for rest of life


u have found that plants maximum ........when it is down do a root ball check size weight shape take a photo.......next time increase your rooting horomones get the ball bigger then step up the plan ....u will see the plant react

PPM is just really for ppl that want to go really deep into feeding ......other wise fallow the plans on the box and just bum it up using MLs untill u see reaction and back down

It is 1400 using .7 conversion meters

I would imagine the 800 ppm they're talking about that of the 5ml/gal of DG is using the .5 conversion, although I've never used DG so not 100%
It's why posting ppm #'s on here without stating the conversion factor is usually pointless

I'm not sure about conversion factors. https://dyna-gro.com/feed_chart/ This is Dynagro's feed chart from their site so this is the info im going off of. I'm not quite as high as their levels yet. Yesterday when I decided to bust out my ppm meter and see just exactly how much food I have been giving them it was 1.5 mL per gallon which came out to around only 250 ppm. Last night they got a feeding of about 600 ppm. From the 600 ppm feeding the run off was about 120ppm. 90-100 ppm is where my tap water is at.
