Strength of nutrient mix: EC ~ 1.1 - 1.3 Using TechnaFlora Nutrients. Did have EC up around 2.8 during week 3 and 4 of flowering.
pH = 5.8 - 6.0
Light system: KIND LED 3W (= to 220W Traditional)
Temps; Day = 75 - 77 Night = 66 - 68 F
Humidity: Day and Night (around 40 - 50% RH)
Ventilation System: YES
AC, Humidifier, De-humidifier - NO
Co2: NO
When the spots first started showing on the fan leaves we thought it from insufficient nutrients so we increased the feed solution strength. When it started getting worse we back the EC down to 1.4 - 1.5. But it has gotten worse. For the most part this is only occurring with the main cola stem. THe majority of the other buds and leaves look good. Is this from disease or nutrient overdose? Can this be turned around? Starting week 7 of flowering today

It is definitely a deficiency or a Mobile (toxidity). You all are going to make my blind ass dig out my J. Cervantes Grow bible and get out the pictures of issues; If you don’t quit linking to offsite data. LOL
Thanks for the info…I’ve since removed the affected leaves and things are looking good.
I think the outcome is going to be a little less yield…but looking for quality with this first Blueberry harvest. 10 days to go! Can’t wait for color changes.
