first grow yellow spots

[NightOwl2018]

Hi everyone this is my first
attempt at growing...

i have Fastberry Auto Fem by Fast Buds...
they are in organic potting soil..

i have 4 plants and 3 out of 4 have these spots and been trying to figure out why...
some of the spots aren't visible when you take them out from under the full spectrum lights...

Calcium deficient.

Do you see any mottled light green / yellow areas as well?
What is the plant age?
What are you currently feeding?
What led lamp are you using?

Solution - cal/mag supplement. Do not be surprised if you cal/mag demands exceed recommended dosing while utilizing LED's.

Thanks...

**the plant is about 4 weeks old
**Phlizon 600W LED Plant Grow Light
**iPower 32"x32"x63" Tent

as i started germinating they took off great,
but then ran out of money so took me a while to get my tent set up and actually stabilized
with temp, humidity. So i was late transplanting them from solo cups then couldn't didn't have
money to get good fertilizer so i picked up Miracle Grow and mixed it to indoor plant directions.
But i think i should have diluted it even more.

i ordered General Hydroponics FloraGro, FloraBloom, FloraMicro Set and Cal-Mag and
i got them yesterday but unsure what i should mix up right now without hurting them further...

what would you recommend for dosage of the flora fertilizer and cal-mag?
what is a good feeding schedule to use?


Thank You so much for you help...
