If its just the lower leaves it may be from getting them wet when watering.

My plant in week 4 of flowering are yellow from bottom up so I think it was nute deficiency sign but also they have slightly burnt at leaf tips on top. My last feed is 750ppm, grow in soil. My routine is feed every 3rd water(f/w/w/f) should I feed more often or same but more ppm

Organic grow, yellow leaves, autoflower
First ever grow. I'm in my 5th week of autoflower, organic grow. Using the bomb paonia soil, raging kush light and boogie brew tea and filter to water. Temps are steady around 86. Started noticing yellowing on bottom leaves. I'm pretty sure it's from under watering? any feedback?

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?

Yellowing leafs.
Hello guys, my plant is now on the final weeks of flowering, buds are getting bigger and the leafs are getting yellow pretty fast. It's this last thing that scares me a little, I know it's completely normal due to flowering but I wanted to ear your thoughts about it. Thank you 😊

Going coco with coco coir!
How often should coco be watered? Some people say every day some people say wait till coco dries up a bit, then water? Been watering every 3-4 days and ive had all kinds of deficiencies. Not sure if it’s from the amount of nutes I use or I just don’t water often ? going coconuts
