Hey it looks like nitrogen deficiency. Buds are taking nitrogen from the leaves and not the soil. Hope this helps happy growing.

Another thing to look at is where/what. Where/What leaves are affected. Old/bottom or new/top. My guess is N, P, and K, unless you have re potted recently.

Is this a CalMag deficiency?
It started with White Widow a few days ago, showing signs of yellow leaf tips. I'm quite sure I'm not overwatering. Are they overfed (nutrient burn)? I use plain water and applied Zamnesia Monster Bud Mix (Pellets) to the soil before the grow. Scared for my first harvest.

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!

Problem in 5 Week of Vegetation
Now in the 5 week of vegetation. The plants are Tropical Gelato cuttings. Everything was great until recently. They looked great. After another light fertilization, the condition of the plants continued to deteriorate. Soil PH value is between 6 and 7. Can Someone help?

Folhas a amarelar! Duvida?
Olá a todos, estou a ter um pequeno problema nesta run, gostava de pedir a vossa opinião, estou na 3 semana de flora e algumas folhas começaram a amarelar, como se fosse falta de nitrogênio, mas na verdade eu acredito que o solo esteja bem fertilizado, posso dar mais detalhes...

Nutrient burn/deficiencies/feeding
Having difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses. One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farms

🙏Greetings... I just transplanted this "Stoopid Fruits" from a Solo to a 2 gal cloth pot after the leaves started to droop and the roots were partially root bound. Starting to perk up but I have some yellow spots, should I clip this leaf off?

Did I go too light with the nutrients this time around? Yellow leaves and fading pretty quick. A good dose of nutes next watering?
My plant has about 3-4 weeks left, I have always had nute burn so I went what I think was way too light w the nutes this time. Is this a nitrogen deficiency along w calmag deficiency? I'm in week 3 of flower, should I give a good dose of nutes next watering? Advice appreciated.

Puntas de las hojas amarillas, otras en garra y otras quemadas, que puede ser? Las plantas están en la 5ta semanita de crecimiento y ya pase a 12/12!!
Ayer regué mis plantas con los fertilizantes grotek colocando exactamente lo que me muestra la tabla en crecimiento y hoy mis plantas amanecieron así, no sé si es por el calefactor que tiene en el medio o por el monster grow que aporta demasiado nitrógeno. Que pueden tener??

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).
