SOIL Soil

Hey forum so I’ve noticed these spots pop up on a couple leaves and I’m not sure if it’s a deficiency or an abundance.. I’ve even noticed the stems start turning purple/redish.. and they kinda look light in color I need help I don’t want to mess these up during flower

3 gallon pot
80 degrees
58 humidity
Mars tsl 2000 at 75% power (will increase in a couple weeks)
3rd day of flower
Been giving regular ph water last 2 waterings
today I gave 4ml of calmag and 2 ml of flora gro
FFOF soil
last run off was 6.4 ph and 780 ppm
Lights off temp 72 degrees

OK i'm gonna ask if these are Photos an the strain? May be the size of pot it's OK for auto but unless it's fabric it won't breath as well larger root mass. I grow photos in 3 gal fabric now but they breath an the roots prune themselves. Any way here we are......did you just switch to 12/12 for flowering? If so it takes about 7-10 to see a pistils. Did you splash the nutes on the leaf?

Yes they are photoperiod plants and wedding cake S1. And yes I just switched them 3 days ago. They were fine last nutrient feeding then I watered twice after with regular PH water and then noticed these spots on them and discoloring and added cal mag and flora gro but as of right now they are looking worse so it might be lockout idk ? I have my light at 26 inches and at 75 strength

It does sound like " lock out now ". Nothing else but to let them dry out you have flushed. Your light distance sounds fine and good to decrease intensity for now. You gotta baby this now for abit just let them rest like your doing reintroduce your bloom food when you see pistils but for now until then i'd give them full NPK for growing.

I'm with SoOrbudgal. Looks like brown spots, could it be potassium deficiency ?

[Tackitor]

It could be a lockout cause after I fed with cal mag and flora gro they turned more yellow so I’ll be feeding plain PH water until I start seeing pistils then introduce bloom nutes at 1/4 power
