Automated ferts start @2.0, 2.6 mid flower, and I'll drop back down to 2.0 late flower. I push as much DLI as the plant will take but 40-47 is my range. Mainly relying on the plant to tell me it's too much then back the lights off a percent or two. I'm too lazy to type it all again but I made a post about nutes a couple pages back.
Thought I'd share a rough idea of my feeding and the current nutes Im using.
First 7 days I hand feed a full solo cup at around 1.0 ec 3 times a day. Once she gets settled in I hook her up to automated feeds. My first res mix is 1.8-2.0 ec and the pump runs for 12 minutes every 4hrs 48min. 5 feeds very 24hrs. 12 mins is overkill early but nutes are getting recirculated and it saves from reprogramming timers. Second 5gal mix for the res is 2.2-2.4 ec. Im currently at 2.4-2.6 ec mid flower and will float around there until late flower dropping back to 1.8-2.0.
I just got home from work. Here are their actual numbers as of today.
Lil stubby first. I don't have a par meter so I use foot candles on my meter. Easy conversion. Every 500 fc is 100 ppfd. Holy shit I haven't used the meter on her for a minute. After calculating DLI I triple checked the reading and it reads higher in spots and around 3500 on edges. I'm blown away right now. That's 73 DLI and I don't see signs of it bothering her.
Cookie monster has a low EC today. It was 2.3 yesterday so she'll get fresh nutes tomorrow or Friday. Let her use some more of the res before I add them. She is hovering around 47 DLI but also has a tiny bit of yellow tips
