I’m going to try that 1:1:1 when i start feeding again. Definitely going to start light though, maybe 25-30ml of each.
It’s crazy that I thought I was slighlty under feeding. Glad you guys were here to help

I’m not sure what the best fluid level is for RDWC. I usually try to get my aeroflo’s levels down pretty quick. You run the levels mostly real high though?

Fluid lv is best kept at 1 to 4 inches below the net pot to facilitate air to the roots. You don’t want the lv touching the bottom of the pot if the roots are already through the bottom.

i meant what you said about the 4 inch airgap?

Fluid level in a RDWC needs to be below the bottom of the net pot.

Any help would be much appreciated. This is my 1st hydro gr
ow; RDWC (6th or 7th grow overall
).
I am not really sure what to do at this point. These two plants upfront have been giving me trouble throughout their entire veg cycle. Finally got fed up with their slow growth and switched to 12/12 on Oct. 24th.
I tried to wait for them to catch up to the other two in height/width but they are just not doing much. Maybe I am doing something wrong, any insight is welcomed.
Tent temp: 75 F
Lights off temp: 66 F
Current Humidity: 60%
Current PPM: 1080
Res PH: 5.5
Current Res temp: 71 F
Using GH Flora series and their moderate feed chart on website
Last full res change was 10/17. Last top up was yesterday. Brought ppm up from 700 to 1000-1100. The only thing extra I add is hydroguard 2ml/gal
Front Strains: White truffle (L) & Marshmellow OG (R)
Back Strains: Terple 17 (L) & Ice Cream man #5 (R)
All from pinkbox
Please help, I just want to bring out the full flowering potential that these plants have

2 EC? you burnt them. they are nute locked now. flush and then start feeding much lighter

Okay, what ppm should I be aiming for?
the other plants seem to be wanting more and are thriving with current feeding regimen
I should also mention that I am using tap water and before adding anything to it the ppm reads right around 200

I chased problems like that... for me it was too low of PH which i didn't realize til i found this chart (one like it, which i cant' find at the moment, but this is close enough) Anyway.. below 6 the uptake of a few minerals drops off drastically.. i used to run 5.5-5.8ish, i went to 6.0-6.3 i never had issues again.. worth a try and won't hurt anyway...

thanks! I will adjust when lights come on. That’s what I’ve been reading about and seeing videos of. “pH lockout”. Plus, everyone makes it seem as if 5.5 - 5.8 is the “sweet spot”. However, it has gave me problems with the two front plants, so i will definitely try this range moving forward

well.. it used to be said that 6-7 is the sweet spot then it seemed to drop, when i started DWC i had issues i just couldn't find then upped the PH to 6-6.2 (normally cause it will rise a bit over time) and i never had those issues again.. like i said.. if it's not right it won't hurt
But i would bet your plants will be much happier.

Another item you can get is potassium hydroxide. Very potent. Be careful very caustic. Read directions and follow. Add with 2 parts calcium. Don't know what ratio with calmag.
But a great tool for upping ph.

use your EC meter to tell you how to feed them.
is your EC/ppm dropping on those bad looking plants?
i like to see a slight drop everyday which means they are eating. and the water should drop a lot per day too

So generally I just get a reading from the reservoir since it is a recirculating system. However, upon reading each individual bucket, ppm/EC has been the same across the board and lowering slightly everyday.
Like I said, whatever I have been doing for the past 2-3 weeks, the plants in the back are really loving it.
The two up front are just tagging along, very slowly growing a few inches per week
About 30min ago I added roughly 15-20ml of pH up (pre-mixed with a small cup of water first) to my reservoir. Current reading is about 6.18 in all 5 buckets
