Help identifying leave discoloring

Can someone help me identify what this discoloring is on my leaves. I did just transplant in to bigger pot two days ago.

Strain - Jack Herrer

Soil in pots, Hydroponic, or Coco? — Soils in fabric pots
System type? — Not sure. Outdoor plans in soil.

PH of runoff or solution in reservoir? —I just transplanted them from solo cups to a 5 gallon fabric pot three days ago. I gave a PH of water about 6. I have only watered once so far at the transplant and used a vitamin B1 mix (even though there are mixed reviews of it, I’m a beginner so I didn’t want to take any chances). However, that water was at a 6 PH

What is strength of nutrient mix? EC, or TDS. - I transplanted the plants to a “foxfarm” soil. Didn’t plan on adding nutrients for two weeks, but maybe I need to start sooner?

Indoor or Outdoor - Outdoor
Light system, size? Outdoor

Temps; Day, Night ---- It has oddly been raining/cloudy the last couple days. Usually it’s around 95 - 100 degrees F and around 65-75 F at night. However last couple days have been 67F during day and 52F at night. I have kept plants out of rain, but have had some rain get to them before I noticed.

Humidity; Day, Night — 80% during day and 45% at night

Ventilation system; Yes, No, Size.–they are outside

AC, Humidifier, De-humidifier, —no

Co2; Yes, No --no

Thank you HornHead. Looks like it’s potentially calcium or magnesium.

Could be nutrient water splash 2


No, that’s definitely Mg deficiency. Don’t pull it because It will spread. It’s very early on and easily fixed with calmag or Epsom Salts

Should I mix calmag in to my next watering and keep mixing it in until gone?

Yes sir. Then add it at half strength on your plain water days. If you see it again go to full strength

The soil ph is too low and has probably locked out the Mg.
Get that straightened out First and you probably won’t have to add anything till wk2 flowering starts.

Ya I had the water at like 5.9 PH for a deep water. I will bump that up higher
