Yellowing of leaves during flower
What is causing yellowing of the bottom/backside fan leaves during week 5 of flower? Should I worry about it spreading? Increased bloom nutrients to 3ml/l recently but could have started when feeding 2ml/l. Or is this just leaves yellowing as a part of flowering?

Help. Leaves on young plant curling downwards
The last few days I've noticed the leaves wilting, I let the soil dry out abit at first because I thought I had given too much water but then last night I watered it with ph 6.3 run off 5.0-5.5 and the leaves still haven't sprung up. Is there something I've done or can do to fix?

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

Light Stress?
Yoo Fellows, Can you share your ideas what kinda problem is it? My first thought is Light stress. Can you confirm this? I don’t see any other problem on the lower part of the plant. Only the top leafs getting yellow at the edge.

I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

Lowers getting blotchy yellow minor rusty spots? 4th week of flower...P/K issues?
What's making these lowers blotchy yellow with some 'rust' spots? Any ideas? I think it's probably a P/K issue, am I underfeeding? Blumat drip system, Promix HP, Maxibloom @3.5g per gal. Ca/Mg @ 5ml per gallon. pH @5.8-6.2.

Nute Deficiency or New Leaves?!
Thoughts if this yellowing may be nute deficiency? Or are these just new leaves and I am concerned about nothing and I’m babying them since it’s my 1st grow? Both plants are about to be 2 weeks post sprout. Both are in 5 gallon fabric pots with layered soil (FFHF on top of FFOF)

Strange yellow patches
This is a new one for me, sont think I've ever seen discolouration like this before. My first thought was having left some nute solution on her leaves after feeding but pretty sure I've ruled that out and more leaves have begun to show the same discoloring. Any advice appreciated

deficiency symptoms
I'm a beginner and some plants are getting fallen leaves. They are being watered with the amount of approximately 10% of the volume of the pot and an average pH of 6.5. Runtz has Mag deficiency symptoms after I fertilized, is she also lacking N deficiency?
