What’s your opinion on this one?
What you think about it? Is she getting too much? I’m not giving her too much in my opinion. Her stems are purple and the leaves are yellowing a bit. Watering always with ph 6,3-6,5. Thanks for your help! Happy growing!

Im getting what looks like a Nitrogen deficency but I have put nutrients on my plants and still the same. What other thing can cause this? PH? All strains are 4 to 5 weeks old and already flowering. Yellowing started to show very early, since week 3 and leaves fall off.

Fatal ovewatering? Will she survive?
Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start. Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?

Lockout or deficiency?
I have an issue with a girl. Newbie alert. I feel it’s either calcium def or nut lockout. I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water. Now it’s really trying to grow, it’s kicking out new leaves but it’s stunted

Lower leaves too pale or yellowing?
I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant. Is this a nutrient/light/watering/lst stress problem if at all? First Grow. Started balcony, moved to tent D23. SF-1000 light, 100% at ~ 55cm from canopy.

Papaya - looks thirsty and starts yellowing on lower half :'-(
My very well trained photo Papaya (Nirvana - Citric x Ice) is significantly decreasing in happiness since yesterday. She looks thirsty but the fabric pot is still heavy and moist (watered 4 days ago), also the leaves on lower half turned yellow today. Too much / little of what?
