Got a few dead/yellow leaves at the bottom. Is this normal at 8 weeks?

answered grow question 5y ago
Yes, this looks normal, as the plant uses up all the food in the fan leaves they will begin to turn yellow in flower especially the older bigger fan leaves. It's due to the plant now getting less nitrogen and more phosphorus to help with flowering.

Ph issue?
Hello, I'm getting a bit worried. I'm not sure does this yellowing happen because of my high ph? I think my soil have been moistured pretty long and wouldn't want to try lower their ph with water. Have anyone ideas what is the problem and how could I fix it? Thank you in advance!

Is this a deficiency?
Hello there, Today I saw that some of my plants have some curled and sad looking leaves (see pic). The soil is pre-fertilized and I currently use normal tap water (p.H. adjusted) for watering. My plants get 18hrs of light a day (approx. 300-400PPFD) Thanks for you help guys :)

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?
