Sieht wie beginnender Stickstoffmangel aus. Eine gute Gabe Stickstoff ist jetzt notwendig. Beobachte, ob die jüngeren Blätter auch langsam heller werden. Und falls möglich, gerne auch den pH-Wert checken, evtl. kommt das Problem daher.

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Alguna carencia?
Veo algunas puntas de las hojas que se están quemando y poniendo amarillas. ¿Qué opináis? ¿Algún exceso o carencia? ¿Debería subir el pH? Quiero corregir el problema antes de que vaya a más. Apenas le estoy dando nutrientes ya que la tierra tiene para 6 semanas: Batmix de Plagron

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Could this be light burn?
Could this be light burn? Only on top new leafs. Have not fed her any nutes yet. I did lower the light after I did LST by the height difference after bending her lower. Have raised the light back up again but just wanted to check what people thought. Thanks in advance

Light green tops
I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.

Discolored leaf
Why the discolored leaf? Maybe the neem oil? Or over watering?

Ph ? Nut ? Not sure what it is on the excess/defiency chart. Details below
What kind of issue here? I think about the pH. -Soil : Light-Mix Biobizz (pH 5,5- 6,5) -Water pH : approximately 5.5 / 6 (initialy 7.4 and I read that is too high, I reduce him to 5.5/6) -Watering : 50ml every 2 or 3 days -Temp and humidity : 23 celsius degree and 44% -Pot : 11L

How much should I feed my plant in week 3?
Hi, I just wanted to know, why do the last Pair of leaves start turning yellow every Saturday. Am I under feeding the plant? Please let me know. Last week I only gave Bruce banner 3ml GHE flora grow, 3ml bloom, 2ml micro, and that in a 5gal bucket. Should I be feeding her more?
