Looks like natural leave colours to me, don’t worry too much just keep an eye on it. Leaves are prone to develop mutations

Leaves Showing yellow edges and banding
Is yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise

Did I do the right thing? Pls check my update on this week!
Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Ciao a tutti. Ho un problema alle foglie più giovani superiori. Stanno avendo delle bruciature e non capisco se sia un problema di troppa luce oppure a causa della carenza/eccesso di fertilizzante. Qualcuno può darmi un aiuto ???

What leaf problem am I dealing with?
Crispy brown tips, dry leafs. What's going on here? It would be weird to see this as nutrientburn cause I don't give that much. It's coming from down and moving slowly to the top. Can I still solve this?

It got a little hot yesterday I think plants hit around 81 at one point when I was gone. Not sure if this is some heat stress and light burn or if it’s a nutrient problem. This is this only plant and only leaf with any signs of this

1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASE
Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Brownish stains after transplanting
What do you think this is? I have recently transplanted it outdoors. These stains appeared the day after. Might it be sunburn? What can I do if that’s the case?

Slightly Brown Crinkly Tips
Dose anyone know what could be causing this browning at the leaf edges? It is a bit dry and crinkly to the touch. This is only on the bottom two fan leaves, and only the very tips. All the newer growth looks fine. Nutrient Burn maybe? Should I be worried, or adjust anything?

Autoflower, deficiency or light stress? End of week 8.
Good time of the day. Having following problems with my autoflower (see pictures) which is at the end of week 8. Plant had some light stress before, could that be a consequence of that? Or could that be nutrient deficiency? Looking forward to hearing from you guys!

Suggestions as to why this plant is a mess!
First grow - Blueberry Auto outdoor. Pathetic thing is on day 36 from direct sow. White splotches since week 2. Subjected to excessive heat, an oversized garden bed, lack of sunlight and overcompensating with supplemental grow lights. CoM organic nute/soil. Any solid diagnoses?

Light burn?
My girls were doing great growing fast until they hit light burn. Growth was immediately stunted for days. I think I have my light problem solved for now, but how long should it be before growth ramps up again? Anything else I should do?

Looking droopy/yellow due to light burn?
Looking like light burn (most intense from the top) and maybe overwatering? I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.
