Leaves yellowing from tip to base mostly in the middle of the plant.

@roberts thank you for your reply. run off is in range. I raised the lights and will add on to the nutrients next watering. Any other remarks are welcome, keep them coming!

Looks like light stress. But could also be a ph issue going on in substrate. What is run off ph? Is it in range? If not there is 1st issue. Next are you getting 20 percent minimum run off each watering. If not old chemical salts build up in soil throwing ph off and causing nutrition problems. Also could double amount of nutrition if your numbers are right in question. Could be lack of nitrogen is why I say adding more nutrition. Good luck. If you need more help feel free to pm me, if you pick my answer. 🌲🌲🌲👊

@OimRausch thanks for the reply she is sitting at 38cm(15") away from a spiderfarmer sf 4000 in the front left quadrant of the tent. I was contemplating the praying leaves, managing the canopy is hard since I do a multi-strain run and on top of everything, all of them are untrained. The substrate is soil. Anyhoodles the water goes in at about 6,2-6,4 PH. My last grow has been 10 years ago so I am fighting on all fronts to dial everything in :P

5th week? why do feed so little? The third photo looks like lights stress, so many leaves turned up... Greets and peace!

Hey, Servus Mate. Thx for the last pic. Your leaves are extremely 'praying'. This is a sign of too much light. I had the same reaction on my last couple of runs. How far away is your light? What substrate do you use, half a Liter daily sounds a bit much.. hope this helps a bit, good luck and happy trails for the rest of the way, servus✌️! OimRausch

Added a picture of the whole plant with natural lightning. Any feedback is appreciated. It is sitting untrained in a pretty crowded 4x4.
