Yellow leaf

Perhaps…Try putting the LED 15 inches away kind soul. This will help tons. I have never needed to have my Mars sp150 LED closer than 12” to canopy. Looking good! Your run will be awesome! 👍 Got one of these Critical Orange Punches on week 12 right now…one or two more weeks to go. She bulks up nicely. Your just getting to the sick part now friend. Thanks for posting mate. Will be following. Peace! New here. Will be posting my grow starting next month. Finishing up a run now. Been growing autos from Dutch Passion for 10 years now. You made a great strain choice! Enjoy. Looking forward to your excitement and continued growing success.

Could be Mag & Nitrogen deficiency. Mag deficiency because the veins are still really green while the leaves are fading. Also it's fading from the top leaves down, so maybe some nitrogen deficiency too. I would give water and add 1/2 strength nutrients at a 6.6 to 6.7 ph. A light foliar feeding of 2ml per liter of liquid seaweed extract and .25 tsp epsom salt to 1 liter spray bottle will help to correct sooner.

nitrogen toxicity, blocks magnesium uptake Good watering regime, plain water with light calmag, like 0.25 ml/L and in few week it will be nice small bushes ready to eat everything you will give them. Just be wise ! less is more in growing ! Happy Growing !!!

Looks like nitrogen toxicity causing a magnesium or potassium lockout. Flush your soil with only ph'ed water and then top feed or foliar spray with langbeinite. Keep this up until the toxicity breaks and your leaves look normal again. Then, do some research on your nutrients so something like this doesn't happen again. I hope this helps.

Ich würde mich da Anonymus anschließen, du hast da ein Kalium Problem. Du hast leider keine Angabe zu Deinem Dünger im Tagebuch😅 Ich würde aber eher vermuten, dass die Aufnahme von Kalium durch einen Überschuss von Stickstoff blockiert ist. Die Teilweise sehr dunkel grünen Blätter sind für mich ein deutliches Zeichen.

Hi there That to me looks like a potassium deficiency.. Are you feeding them with any feed yet? Cant see any info on your diary, I will give them a good nutritious feed, Best of luck 🌱
