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.

 

[dirtymike]

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

 

[DoubleA]

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

 

[dirtymike]

Fox farm always was a little hot for me.

 

[dirtymike]

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

 

[dirtymike]

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

 

[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 🌱

 

[dirtymike]

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

 

[kingfish]

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.

Updated pics…..at 50 plus days 4 wedding cake autos and 1 Do si Do auto. separate photo is of the wedding cake that’s ahead of everyone else.

Looks like they may need more nitrogen overall or PH issue. It's so hard to get them back right when they are in flower IMO. I'm not a master grower so idk how well my advice is

 

[Bluey]

I agree with HobbitGDF on both points re N, pH and sorting them in flower. Just use best practice and push on.

Your plants needs across different cultivars is completely different. Also the uptake of water and watering amounts. If you had more run off in a soil grow it would stand to reason that plant will get less of everything, as its been washed out of the pot.

Thanks for all the input…. I’m going to just keep on, keeping on growing. I ll keep posting updates to see how this turns out. Like a science project

Jiffy pots are a no no. Stunted root growth. If your air flow is proper the top of the soil should evenly dry. The front left you can see the dryer side of the pot. My assumption is wet, no roots or little root growth, dry is where the roots are concentrated. When you use those starter pots, not all roots are strong enough to break free. So the weak and little ones die. Next time either germinate in a paper towel then go straight to a red cup or small pot with holes in the bottom for drainage. Then transfer to the big pot. Start there....It will give all roots freedom to expand. Just my opinion......Not enough roots to feed them the amount of nutes they need.

I ripped the bottoms out before I planted…for that reason just like I do tomatoes 🍅 lol
also updated photo we at about 2 months now.
