Hey Tokey... This looks most definitely like a nitrogen deficiency - but since you don't have a diary, all you're going to get here are guesses because it could be something else, too! Is your PH in a good range? This could be a lockout issue where you're giving enough nitrogen but the plant just isn't able to absorb it... in that case, you'd need to do a flush and start your feeding over again...
Do yourself a favor and start a diary so that when you have questions or run into a problem you need help with, the community will have as much information as possible to help you out!
Good luck!

Look like mostly Nitrogen deficiency and may be potassium a little as well.

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own.
I’m not sure if it’s a nutrient deficiency or blockout from ph or something else.
I watered them only with water ph 6.5.

Blätter gelb und fallen ab Blütewoche 9Aktuell machen mir meine Pflanzen echt Sorgen, viele Blätter werden sehr schnell gelb und fallen von allein ab obwohl ich bei jedem gießen Dünge.

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?

Yellowing, wilting, stunted growthCan anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.
