light green leaves - Not sure what deficiency this is?
- Thread starter joe how
- Start date
Plants are in week 2 of flower. I have tried everything. I increased my irrigations from 1 time a day to 2-3 times a day with 15-20% run off each watering.
Info about grow:
Coco mother earth
GH flora series
PPM: 1100-1200
PH 5.8
CO2 1200ppm
humidity 50%
temp 82*
I calibrated all of my PH meters (4 of them) to confirm this isnt a PH issue.

They definitely look hungry for nitrogen. Their preflower stretch (the 1st 3 weeks of budding) uses alot of nitrogen up. Try giving it an equal dose of bloom, cal/mag, and veg. Nute. You seem to be basically in hydro? So I not sure how the flora line works. As I only play in the dirt. LOL

How much each of the trio are you using. How many mL of grow, micro and bloom?

I dunno about nitrogen. Wouldn't his lower leaves be yellower than his uppers?They definitely look hungry for nitrogen. Their preflower stretch (the 1st 3 weeks of budding) uses alot of nitrogen up.

Good point. But top right of fella growers pic shows some mightily wilted yellow leaves. That's just what brought me to that possibility. I could be wrong. But I do know every strain is a nitrogen HOG/feeder during the pre flower stretch period.

Absolutely They are hogs for N in preflower. I'm not counting it out. It looks like they could use N but also something else. I hate using the flora grow. I like using the Lucas formula. I think it's better.Good point. But top right of fella growers pic shows some mightily wilted yellow leaves. That's just what brought me to that possibility. I could be wrong.

I use dry organic nutes amended or top dressed in Dirt. So I don't know about those liquid nutes. Or the PPM's as there is no need to measure that wi organics. So I may not be the best source of hydro knowledge.

I'm in living soil myself but I've done hydro. I like the growth rate but it's kinda a pain unless you can stay on top of it. Living soil is easier and less stressful for me.I use dry organic nutes amended or top dressed in Dirt. So I don't know about those liquid nutes.

Mee Too. Soil wise that is!

I grow in soil. But I know some people who use that. Are you adding any Epsom salt? Looks like Mg deficiency for one thing. You might need to up the GH amount too.
@Doug Dawson uses it.
I posted this in multiple forums and majority of responses were im under feeding, which I also think is the case. But I tested my run off PPM and it’s still higher than feed PPM.
I’m feeding 1100-1200 PPM and run off is 1800 PPM. Run off PH is 5.9. Doesn’t this indicate to much nutrients
