Looks like a phosphorus deficiency. I would start by checking your substrate ph first. I just has same issue this last weekend. My ph was crossing to a unsuitable range. Good luck and happy growing 🌱

Light dots on leaves
I am careful only to spray the plant right before the lights go off - what could these light dots be? (Info about the nutrients I used in the diary.) Thanks in advance!

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

Plants react to darkness in different way
During the night, I have noticed that 2 plants out of 3 stand with normal leaves straight, while 1 has leaves going down during the darkness and when the sun rises, it gets back to normal. They are all same strain, grown in same way, why?

Brown spots on bud site leaves?!
halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏

Spider Mites 1 week before harvest
1 week before harvest I saw some white dots on some of the leaves which might be spider mites. It's not that spread out yet and only on a few small leaves, I have seen no webbing either. Do I harvest ASAP or will the plants endure a few more days without it affecting the buds?

Small marks on leaves a concern?
I noticed only a couple leaves out of a 4x4 gg4 grow show weird marks. Just wondering if it's cause for concern since it's my first grow. Otherwise they appear to be perfectly healthy, growing great and praying going on 4 weeks into flower.

Fan leaf finger progression
I read somewhere that a healthy plant should increase fingers with each set of leaves. Wendy had two 3 fingered leaves, one of which wasn’t clearly defined. The next set of leaves look to have one with 4 fingers and one with 3. Should I be worried? Does she look healthy?
