At week 8 started to get a few leaves like pictured. Auto Bruce Banner, soil in 2 gallon fabric pots, ff ocean and perlite. 2000 w LED on 20/4 cycle. Doing light liquid feeding. Tap/City water no pH testing done.
Any thoughts ?

Oh, there are two Super Lemon Haze in the back right also.. similar marks.
 
Spent the evening reading about everyone's leaf problems...I ordered a pH tester and up/down. Seems like the next step... don't just add calmag with no evidence. Probably some element lockout due to water. They do look pretty good overall, first tent/autoflower experience. Can't believe these girls are only 2 months old !
 
@Redzo :welcome:welcome to AFN:welcome: That looks like a Phosphorous problem but too much or too little or is it a lock-out? Can you give us some more information.

Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)

-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics! Turn off the grow lights.

Thanks, will update when I get my pH kit. Never seemed to need it for my outdoor grows but this is much more intense...seed to bud in 10 weeks! Thanks again
