Hola Farm,

Wanted to get some input on what my plants are trying to tell me. I'm thinking C deficient....

Plants are 4th week of veg, photos are GSC, but also seeing the same issue on the OGs however it is not nearly as bad.

Growing in Coco, third run in the same coco, had similar issue last run, but wasn't as bad and cleared up faster
Precharged with mild Veg+CalMag once before potting
Running Canna Coco, current feedings:
8mL A+B
9mL Zym
7mL Rhizo
4mL GH CaliMag

Vegging under DE 1000s, lights are bout 7' from lights

Couple of notes
- atmosphere has not been ideal (AC issues), much colder than I would like, between 70-75 most of the light cycle, humidity between 35%-50%
- found out my CO2 monitor is not shutting of my gas so room has been getting flooded with CO2, not sure what it has been consistently, but def over 1500, possibly even getting 3k+

Much appreciation

Oops, think I posted same pic twice

A little more info....

- plants are from clones
- running tap, comes out at 80ppm and always let it bubble for at least 24 hrs before adding nutes
- ppms are currently around 700
- room is roughly 20' x 20'
- water every 3-4 days, slowly ramping up, end up feeding every other day once they are switched
- plants are in 7 gal fabric pots
- currently vegging under 8 1000w DE
- plants are all between 12" and 24" tall
- pH around 6.0

Appreciate any input
much love

I see a possible Ca- and definite P-. Going at a Ca- now is chasing your tail, you'll only be able to stop progression, it cannot really be corrected. Ca can be applied via foliar and root drench methods. Everything else looks alright, but I haven't used those nutrients so I can't really speak to them. I'd say offhand, raise the nutrient level here.

Don't ask me how much CaliMagic to use, I don't use combination products. :p
