Looks good to me mate, nothing to worry about. Maybe nute splash. Definitely not light burn. You could use higher humidity though. Have a look at vpd info if you haven’t already.

Good luck with it.

I do have a humidifier in the tent, had the RH up to about a steady 70% for couple of weeks and temps at 75F - 80F until I had to open the bottom vents to let cooler air in. I will figure something out.

Thanks for having a look

That is the beginning of a nutrient deficiency caused by closed stomata. The plants cannot transport nutrients when transpiration is slowed or stopped no matter how much is in the pot. The water needed to carry the nutrients into the plant is stopped with nowhere to go.
Get your RH >40% and 60% would be much better.

Looks like the issue is slowly getting worse:


I will watch the humidity closely. See what I can do with lowering the humidity level between 40% to 60%

I managed to get my RH between 55% to 60% and temp between 70F to 75F

Symptoms spread through out the bottom leaves of this plant:

Another plant has faint yellow dots and droopy leaves:

The drooping leaves could be that I need to water which I plan to do tonight.

Should I continue to feed this watering using?:
5ml per gallon of Sensi Bloom A+B PH Perfect
2.5ml per gallon of Voodoo Juice

Should I add calmag?

Or should I hold off and only use plain water Ph to 6.0?

Your plants will much happier and will use a lot more water now so be careful not to let your pots get too dry. What nutrient schedule are you following?

Ok you need to get an EC meter because even though you have volumes it does not give you the strength in numbers to compare. I would not feed Autos over 650 PPM not counting your starting water. The frequency of feeding makes a big difference also. I think feed, water, water, water repeat. Is a good place to start.

You are using organic soil? Which means you should only Ben feeding water. They look okay just now but if it is organic; then do not feed it fertilizer.

Edit:
Sorry just realised it wasn’t living soil. Okay so your 5ml sensi Is really concentrated so definitely use less additives and cut down the dosage. 5ml is strong And you should use an EC Meter to see how strong ur feeds are first. I never go over 1ml per litre in coco with sensi line up
