Hi guys,

Just wondering if you could give some advise on yellowing leaves. It's my first grow, i'm using soil, fabric 5 & 7 gallon pots in a 4x4 with SpiderFarmer LED's and keeping things pretty organic.

I'm a few weeks in to flower and been feeding with Canna Bio Vega then after the stretch been using Canna Bio Flora at the recommended dose. Since the flip been adding CalMag once a week. I also have a BlueLab pen, properly calibrated and PH the water to the 6.3-6.5 range. All water sits for 24hr with an air stone prior to adding nutes and feeding.

It's not happening on all plants, the effected strains are Jack Herer, Northern Lights and White Widow.

Thanks for any help.

Nitrogen hungry. Can cut cal mag back to half now.

Thank you so much mate, i was guessing Nitrogen from the charts but couldnt be sure if it was a toxicity either because it feels like i've been feeding them enough going by the recommended dose. Good thing i didnt do a plain water flush it would of compounded the problem.

They have just gone in to lights off, so i will feed them some more Nitrogen in 12 hours. Interesting you said 50/50 i was doing this for a week during the last week of stretch to transition them from Vega to Flora. Looks like they didnt like stopping the Vega despite being in flower a few weeks. Thanks heaps 🙂👍

That's funny cuz walleye is one of my dream fish , we're going to have to swap places soon 🐟😂
Oh you aren't kidding.... I can catch hundreds on a good weekend. I would give up fishing for a yr to be able to catch a blue marlin... hell maybe even a couple yrs.
