I’m currently 1 week into switching to 12/12 and after watering today (Just PH 6.15 water) I checked the PH and PPM of the runoff. Currently 6.52 PH and 215 PPM for the runoff. PPM still confuses me a lot. With PPM this low should I be increasing my nutrients? I’m currently using the FoxFarms trio and watering twice a week and adding nutrients every other watering. Should I water with nutrients every water? Or should I just keep the current watering schedule I’ve been doing? Sent from my iPhone using Grasscity Forum
I'd suggest. Feed , ppm 600-800 , ph 6.5 Let dry a bit longer and fresh water ph 6.5 in between feeds That would be for soil If you're in coco that's a whole different animal Sent from my SM-G975U using Tapatalk
Feeding Schedules - FoxFarm Soil & Fertilizer Company Use their feeding schedule, can't go wrong , After a successful grow you can start tweaking the nutrients around Sent from my SM-G975U using Tapatalk
I’ve been following the feeding schedule but this schedule says water with nuts twice a week and I’m doing it just once a week. Is this why my PPMs are no where near 1,000 I’m at just 215? Do PPMs matter much? With 215 PPMs in flowering stage should I up my nutes? Sent from my iPhone using Grasscity Forum
Are you testing ppm on runoff only I noticed you mentioned your run off ppm but not your input . And how much solution are you giving the plant at one time , Sent from my SM-G975U using Tapatalk
I was just checking PPM on runoff. I want to say a few weeks back I checked the PPM when I was just using 3tsp of Grow Big per gallon. I do what the chart says 3tsp of Big Bloom, 2tsp of Grow Big and 2tsp of Tiger Bloom per gallon and I water my 6 gallon pot twice a week (1 gallon each watering). I can increase the nutes I give. What should be my target PPM during watering not runoff do you think? Sent from my iPhone using Grasscity Forum
See the chart where it says ppm , thats the estimated ppm for all nutrients combined , That doesn't include ph up/down That is the ppm range of the solution going in Sent from my SM-G975U using Tapatalk
So I watered with normal PH water no nutes today do you think I should water a gallon with nutes with higher PPM? Sent from my iPhone using Grasscity Forum
Yes I'd start at 600 and work up I usually feed at 800+ in early flower with fresh water in-between Sent from my SM-G975U using Tapatalk
I thought in a soil grow ppm at runoff is basically meaningless? But in coco it is essential? I've tracked my ppm going in, but never checked runoff. Using FFOF here. Harvesting in 3-5 days so just curious for my next grow.
I’m an idiot, my PPM meter has x10 really small so I’m actually looking at 2,150 PPM which is far too high... Sent from my iPhone using Grasscity Forum
Should I flush? Or just use regular PH 6-6.50 water for a week or so? Sent from my iPhone using Grasscity Forum
That sounds about right , I was going to mention your plant looks good Only see a couple brown tips which tells me she's being fed Sent from my SM-G975U using Tapatalk
I fed more nutes just before I realized my PPM meter was x10... the runoff was like 2,600 PPM should I run another gallon on PH 6-6.5 water through? I don’t want to overfeed and burn them or should I wait until I water again on Wednesday and just use PH water then? Sent from my iPhone using Grasscity Forum
Run off of 2000 is a bit high I would run a couple cycles of pure ph'd water like a half gallon at a time Let it dry out between then after a couple of those give it a full gal light feeding like 600 ppm and check the run off and build back up , check your ppm on the way in Sent from my SM-G975U using Tapatalk
