My guess would be PH and or magnesium. 5.8-5.9 in veg. 6.2-6.3 in flower. Good Luck!

inner leaves yellowing
I've started to notice that my leaves, mainly the larger fan Leafs, are starting to get a lighter color in-between the veins of the leaf with dark green around the rest of the leaf. not sure what this means? I use only organic nutrients only (no bottle nutes used ever)

Orange Spot in first set of leaves
If you can see Veg Week 1 Photos, Photo named Day 7 Zoomed, I have been seeing these dots for 2-3 days now. What is it? how can it be solved? FYI - These were the first set of leaves, others look healthy. My guess - nut water got sprinkled or cal/mag deficiency.

Is the plant just maturing or something else?
I don't think this auto CBD plant has long to go. It's at 59 days of a supposed 65. I just started to notice a some tips beginning to discolour and a couple of fan leaves have small yellow spots appearing. Is this just the plant ageing?

Raise PH of soil? Is run off actuate reading of soil PH? One of my plants might be getting sick, I need a fix for this ASAP!
So quick question... how would I go about raising PH of my soil. I just took a reading about 5 mins ago from my runoff and it was like 5.8!?! It’s never been 5.8, and I do have a little issue with 3 of my fan leaves on one plant. No soil PH meter. Just flushed them 5 days ago...

Leaf issue
What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.

CalMag deficiency?
I have had it 2 times in 7 weeks, the leaves are bright orange. I'm adding now 1,5 times the normal amount of CalMag. Starts with small spots in the middle of the leaves and progresses towards the veins. Always happens in the middle of the canopy Am I overlooking something?

Leaf colour help. Hi all. I think there may be a problem with the new growth on my plants. They are 10 days into flowering 12/12. They look like they are too light. They veins are much darker giving them a stripey look. I had the light very close to them when it started. ?

The ph value is 6.3.👍 Yesterday I poured Short Flowering Powder "0.5g / 1.5l" in ph 6.28 water and today I notice these yellow spots. The beauty has grown 5 cm since yesterday.💪 What could that be? I'm just a bit worried?! 😲

Exeso de luz? Bloqueo de nutrientes?
Los nuevos brotes de mi planta salen con un tono verde lima. En la zona que más luz hay parece empeorar, será un exeso de nutrientes/bloqueo o quema de luz? La lámpara está a unos 40 cm

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?
Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.

Cal or mag def?
Believe this is a cal or mag def. Didn't begin supplementing until last week (2ml organic cal-mag per gal), but they're getting it w/ every watering now. Lightening between veins on higher sites, minor rust spots on lower sites. Think I can ride this out,but wanted to hear others

Upper leaves are yellow and not smooth
I noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?

Discolouration progressing
The first pic is from 2 days ago, now the yellow has turned to brown spots and is beginning to spread to others. I'm hoping it's an easily corrected nutrient imbalance, please help

Light spots on leaves
I have some spotting starting on a few leaves. I had some slight tip burn last week I believe from letting the soil get too dry and getting a bit of nute burn. Two leaves showing these symptoms.

From the start I’ve been watering with ph 6.5. I just discovered my runoff is 7.1 and I have what I believe to be a zinc deficiency. Similar issue on my previous grow. How can I fix my watering routine such that the ph stays more stable?
