Grown in Roots Organics Original Potting Soil
I was told to start adding nutrients after 3 weeks, i waited 4 weeks because I didn't think they needed it. I then added the nutes at half strength for the 4th week (which was last week). Now this week (5th week), two days after my third and strongest watering these few signs started to show.

They're shiny and lighter green towards the edges of the leaves.
Also the new growth might be slightly yellow if that adds anything.
The effected leaves vary a bit, but are mainly new.
Pictures are a 1000's words so I attached a few
THANKS so much in advance! Any suggestions/comments/questions are very appreciated :) !IMG_0807.jpgIMG_0811.jpgIMG_0812.jpgIMG_0813.jpgIMG_0809.jpg

Is this in a tent? A picture of the whole tent so i can see fan meters and such is needed.

Thats transpiration problems why the outer edge is lighter. It took me years to nail down this and find the reason leaf edges allof a sudden start failing :-)

Early potassium deficiency.....

Check Ph .... you should be at 6.5 ( Going In ) to medium.
Check your Nutes used and NPK .
Use better nute with higher ratio or use potash or kelp to correct.
And a tall can of beer ( it will be all better .... promise )

Is the beer for me or the plants? im kidding, ill be relaxing shortly haha. (i'm assuming you meant it's for me)
I have a PH checker I'm using but it's cheap and might be faulty so I'm gonna get another one just to double check.
I'm using the Aurora Innovation soul player pack for nutrients but as I said waited a week after they suggested adding nutrients and have only been using 1/2 strengh. I'll use full strength this next watering and look for changes within the next few days.

Yes, it's in a tent. It's in dark period right now so I'll send photos in 5 hours ish. I thought fan speed could possibly be an issue (if thats what you were gonna say) because I realized my fan was on a higher speed than usual, but its only one fan and not too strong.

Plants hate wind, was just riling out the basic issues :-)

Plants hate wind? They hate too much wind. From seed or clone my plants have fans. Big roots, big fruits and thick stalks which are like pipelines to the tops.

First off i was shocked myself to learn plants hate wind, it diminishes their boundry layer and means leaf cooling via transpiration is forced and not of a free nature. Secondly as with everything there is a leve, as you suggest, where the wind becomes too much and cooling turns from free to forced.

This rabbit does nay know or have the exspensive scientific instruments to accurately quote the wind speeds permissable for mj but after months of cross referencing most and especially similar plants that have been highly studied (not by mj scientists but real actilual scientists, one figure stands out and that is 0.3 to 0.5meters per second (some plants go up to 1.0 as a general max). Now i warn you this is barely perceptable by human senses and at 1 on the beaufort scale.

Most will create this with just exhaust and that mixes the entire volume of tent air - most have far too many cfm and havent got thermometer shaded so try to use wind speed to cool the thermometer which the light is heating.

This is all google for the educated but it made me form a question so i could quickly defeqt those that keep thinking plants need wind.... 'Do plants keel over dead in stagnant air?'. The answer is no and many a greenhouse ive been in with still air yet the plants thrive. Scientifically the leaf is hotter on its surface so convection currents start up between the bottom surface of the leaf and spill air of the edges upwards whichs sucks in more. Leaf energy budget science stuff.

Its just mj sites that think plants need wind, major greehouses of the world arent wind tunnels or even blowing wind on their plants but theyare mixing air with fans at equal spacing and exhausting heat when needed.

I'm willing to take my chances. 40 years of huge colas and stems that can support them have me hooked. No fan no exercise.

Howd you fix the transpiration problem? I got the same problem.
