Gooooood morning friends!!!
I need a little help, in the last 3 days I've ran into a deficiency I need a little help with. First off, I'm growing in a 4x4x8 tent, 2 LED SpiderX plus, co2, running canna organic nutes, cal/mag, molasses 1 time a month, Dirt is roots organic greenfields, growing in 5 gallon pots, Bruce Banner #3 from seeds. Watering schedule 1 day fertilizer, 3 days RO water
What I think im seeing is a potassium deficiency. What do you guys think?
First of all you should be doing it the other way around, nutes for 2 days and plain water the 3rd day. Also i use
bluelab meters and they are hands down the best. You can get a soil version for a good price, around 200 canadian i think.
I can help you out a lot more if you tell me everything you can
What nutes you use?
How much do you feed/ what is the ppm/EC?
Anything else that might help?
How much magnesium / calcium is in your soil?
It looks to me like either your pH is way off or youre experiencing lockout from overfeeding/pH imbalance
Before you try to add anything you should leech the soil. So for the 5 gallon pots you want to pour 10 gallons of water through them. This is the entire reason that i never used fortified soils or soils with nutes added already (back in my outdoor days). Because soild like that or like
fox farm (dont even get me started n those screw-ups) because it makes it very difficult to know exactly what is going on. Are there still nutes in the soil? If so how much? Are all the essential elements there or is only nitrogen left? Is there a salt buildup happening because of over ferting from having no idea whats in the soil? When i switch to flower will there still be veg nutes left in the soil and if so how much? I could keep going but i think you get my point.
Give me all the info you can and i will try me best to help you out. Happy growing.

Oh shit i almost forgot, you need to move fast. Plants can cross a threshold where the leaves no longer have sufficient chlorophyll to photosynthesize.
