Help…..Yellowing Problem?

[DoubleA]

Okay so not my first grow however I’m not sure what happened any thoughts would be appreciated.
4 wedding cakes and 1 DoSiDo….All planted in 5 gal fabric pots with Fox Farms ocean forest and added perlite. All on same watering, lighting, and fertilizing program. For whatever reason the wedding cakes all are yellowed while the Do Si Do in back right corner is still way greener. Additionally, the one wedding cake in back left corner is ahead of all the others. (Separate pic)
Any ideas? Suggestions? I’m thinking maybe it’s just genetics bc they all seem and look healthy

Looks like Cal-Mag def and ph issue in flower. Every plant uptakes nutrients at different rates, (different cultivars) If it's there it takes what it wants until it's gone. The PH scale shows which nutrient is available at a certain PH value. I water at 6.3-6.5 during flower.

I always get a little yellowing at beginning of flower then correct my ph and neutrient values. I seem to always burn the tips before yellowing on the indoor grows.

Tip burn almost every grow.

Thanks for the insight, I’ve hit all them with cal-mag twice now….been watering at 6.5 the whole time. Seeds are from different places…so different cultivars and different strains.

I think maybe I started too late with the fox farms trio, for the wedding cakes fancy. But the Do si Do was fine with it lol 😂

[dirtymike]

Yep, I try to stay with the same cultivar but it seems to never happen

Thanks again and I’ll keep ya posted on how this turns out

[dirtymike]

That looks a lot better than the first pic, not much yellowing going on now.

Fox farm always was a little hot for me.

Coco coir and perlite for indoor. Bugs got to bad with FF.

dirtymike, I agree with you on bugs with FF. That is why I switched to Roots Organics years ago. I see they haven't improved yet.

[DoubleA]

Yes they are looking better I think you’re right….different cultivars and strains. I threw the do si do in at last min bc I couldn’t get a fifth wedding cakes fancy to sprout 🌱

Do So Do is a good strain. There is a grower in here mainlining Do Si Do. Big Colas
