White/yellow spots

[Wclazerdub]

Problem: Today I found white/yellow spots on one of my plants.

Medium/grow method: coco/peat/vermiculite

Feed: and supplements used: dr. earth all purpose + all purpose bloom 1/2 strength in soil

water source: un-ph'ed tap

Strain/age: 4 weeks c4 and blackberry fastbuds

light used: 14 100 watt equivalent led bulbs 30k and 40k

Climate: 77F RH:60%

Additional info: looks like its spreading to another plant

Everyday there's something new!!!

Thinking it is a Cal/mag issue but after reading it sounds like a bacteria issue or maybe mites

These are indoor and my other 7 girls look great.

What do you think?

I usually go full strength after plants are around 30 days old.
