What do I have here

Wyodub · Mar 23, 2023

Ice cream cake regular seed. Haven’t sexed yet.
10gal fabric pot in ocean forrest/strawberry fields.
KindLed x750 at 100% (no IR yet) hanging about 16” above plant
4th week of veg
Gaia green with some other organic amendments

Save this link. It's pretty handy. https://drcannabis.io/symptoms I'm thinking light stress. Whats it planted in soil wise? What organic amendments? I start my plats indoors for about 2 weeks maybe 3 then outdoors 100% organic the last few years so there will be guys that grow indoors around to offer more pointed advice for indoor.

if that's going at 100% less than 24" away for a plant that size i am going to automatically assume light stress.

The amount of yellowing looks like it increases, going from the top branches to the lowest branches. Is light stress more apparent on the top leaves closer to the light, or more visible down low where nutrient uptake is?

Gonna agree with the hotdog @Cirroji that it's most likely light stress/light burn at this point (which can and will drive other deficiencies) and it just hasn't had enough time to happen on the new growth yet. You mention you are using GG and "other organic amendments" can you tell us exactly what and how much of the other stuff you've given?

Are you using tap water?
Have you given any Epsom salts at all?

Step 1 is to drop that light to 40-50% intensity until she recovers.

I wasn’t looking at the far leaf edge tips. What I was going off was the whitening of the inner leaves which is worse at the canopy level.

I worry more about new growth than old growth that can easily and normally gets trimmed off with pre flower defoliation.

breedwheel · Mar 23, 2023

Looks like it's a light issue to me but that big bottom leaf under the canopy makes me wonder. Are they drooping like that a good while before lights out? Not just the hour or so before but like 4-5? Mine were doing that when I was too high in intensity but before the leaves started the browning and clawing

freezeland2 · Mar 23, 2023

What is the temp & rh? Preferably leave temp if known. I agree with @Shaded_One about turning the intensity down on that light. Don’t know if the deficiency in the lower leafs are from lack of nutrients or a nutrient uptake issue. It’s why I asked about your rh & temp. Could be a vpd issue contributing to this.

Shaded_One · Mar 23, 2023

serrated leaf edges, taco leaves, canoe shapes...typical light stress but +1 to @freezeland2 for the VPD as that is also probably a culprit

you can see the burn juuuuuust starting to happen on the edges of the latest growth, these gals aren't happy with their environment and are not transpiring well :)

Observationist · Mar 23, 2023

VPD-related.
Light is perhaps a little too intense.

It could use a little more food.

mysticepipedon · Mar 23, 2023

I wouldn't mind seeing another pic or two of the whole plant, including one from the top.

It has started mainly from the bottom of plant and worked up

I have top dressed GG and all purpose and some kelp around week 2-3. Been watering with fish shit, silica every other watering. Watered in insect frass at week 4. Using RO water with 5.5-6 PH. No Salt given.
I’m not 100% sure this is a girl. I have three other plants in tent that are girls that are doing great with same feeding and no deficiencies. Two are Blue Dream and one is Tropaya. This ICC I’m waiting to see sex to see if it’s gonna make it so I’d rather not drop power of lights unless you think that’s appropriate

Been struggling at times with environment. I’ve had some hot and humid conditions for half a day that could have caused some issues. Typically though temps hover around 70°-80°. Humidity 45%-55%

It can be either. If the light is only slightly too intense, the lower and older leaves may show stress first because they have been exposed to the light for a longer amount of time. If the light is more intense, the stress will show on the top leaves first because they're closest to the light. In that case, it can be thought of a burn or bleaching.

I think a lot of what is going on can be improved if you got the vpd under control. I’m making some assumptions here but if temp is 80 and rh 45% the plant is over transpiring. If temp were 70 and rh 55% the vpd is in a safe zone but it is to cold to transpire correctly. Do you have any means to control the temp & humidity parameters to achieve the correct vpd for the plants growth stage. You would probably see some improvement if you can achieve and maintain a vpd of around 1.2 kPa.

RootsRuler · Mar 23, 2023

Are you sure you aren't overwatering? Those leaves look mighty plump.

I agree the main culprit looks like light burn but the edges burning like that could be nute burn? Especially since it's coming from the bottom up. I don't use dry amendments so I'm not sure if you can nute burn with them.

Seeing vigorous growth good but for some minor deficiencies
