Help me diagnose this color on my leaves. I don’t if it’s something to be concerned about I just don’t want it to get worse. Overall I think they look great. What do you think?

I believe you are experiencing ph fluctuations. I'd calibrate your ph pen if you use one, if not I would recommend one.

They look ok. I would say 2 things, too much nitrogen and not enough pk, correct these and you should be fine going forward

what's wrong?
this yellowing that starts from the edges and ends up drying out the whole leaf is only happening on the hulkberries (the fat banana looks great) so now I just don't know what it could be 😭

Help, my leaves are dieing, I think I may have been overwatering. Is this a symptom. Spiders and slugs are a problem too any tips? I laid back on watering and new growth has appeared, it’s a fine line though before they dry out in the 50 deg peak temp.

Light stress?? Wilting leaves, shrivelled and burnt edges. See pics in last week.
Any idea what’s going on? Leaves are shriveled and wilting, as well as some burning at the edges? I’m guessing this is from light burn/stress as I’ve only watered and used very very little nuts so far. Lights were at 22 but now at 30. Temp is 24 w lights on, 55 humidity. C pics.

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

First, the lower leaves started turning yellow much quicker than usual during flower. I didn't change any Nute levels in my water because I wanted to see how things went. Then we had a few really hot days then this started happening to the leaves. more detail in week 17

Is this light burn?
I am pretty sure it is led light scald but just thought id try to verify. I have a new 650w Hortibloom light bar and have been running it between 400w and 650w at the top of the tent. I'm guessing 650w, even at the top... is too much? They are in soil, and I'm using gaia green

Nutrient burn?
The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?
