This happened overnight...

I dont know what could be wrong with this girl, end of week 5 veg... also the stems are turning a red color.
-ffof/happy frog + 30% perlite
-no nutes
- 1000w mh

The no nutes would be a starting point....as that's a deficiency.

the soil is 10 days old, there is still alot of nutes in the soil as is... 5 gallon pots

According to the chart it's either an iron or zinc deficiency.

Your plant isn't absorbing micros... whether they're in the soil or not. It's probably not gonna kill your plant but she's asking for more micro nutrients. What was the plant in before you transplanted?

1 gallon pots of FFOF/happy frog+30% perlite

PH imbalance causing nutrient lockout. What is the PH of the water going in? Are you using RO water? On a scale from 1 to 10, 1 being dry and 10 being extremely saturated, where would you place yours?

Also, environmental specifications are critical to a proper diagnosis. Temps, humidity, light distance, light wattage, open/air cooled, etc...

The absolute last thing you need to do is throw more nutrients at it, though. I would add a rhizo supplement to PH'd RO water and let it sort itself out. A foliar spray with compost tea or rhizo would do wonders as well.

I use reverse osmosis filter water, ph is 7.
Soil is typically dry and I rate it around 3
