Is this wind stress?

[HeySam]

I’m using a 50 watt oscillating fan, in a confined room i improvised.
Please advice
240 true watt led
Strain: unknown lebanese
Room : 2.5x2.5 ft
Day 20 flowering.
Should i defoliate? Some bud sites are too close to each other.

 

[CanadianJim]

I wouldn't defoliate a plant unless she was in good condition, and taking away budsites in flower would tend to be counterproductive.
Is the fan pointing directly at the plant? What is the room temp and humidity? What are you feeding her, and how often?
The more you can tell us the more we can help.

 

[HeySam]

I fed her once a 20-20-20 feeding. A month ago.
The humidity is roughly 60% temperature 25-28.
Growing medium peat moss ph 6.5
Never fed her again.
The fan is hitting the wall but the leaves are shaking( at the least speed).
You suggest not removing 2-3 small bud sites to increase light penetration.
This is my first grow
And had to rush flowering because i need to relocate to another continent

 

[HeySam]

Forgot to mention
I defoliated the plant (10%) of lower leaves and few fan leaves covering bud sites. Also removed hidden bud sites 10 days ago.

I'm a beginner aswel but to me looks like wind and heat stress I may be wrong

 

[CanadianJim]

As long as the fan isn't pointing directly at her you should be good. I'm pretty sure she's just underfed.
The rest of the conditions there look good. The humidity could be a bit lower since you're in flower, but the air flow is moving the leaves, so that's good.
If you can get some tomato ferts, or something with lower nitrogen and higher phosphorous and potassium, that would be good. I used to use a 3-6-12 for bloom. Now I use Mega Crop, much easier to use the same nutrients through your grow.
Defoliation can wait. I never did defoliate when I grew indoors, I bent the petiole (leaf stem) and tucked it out of the way.

My vote is windburn. You want just enough of a gentle breeze to make the leaves move ever so slightly. They are curling in like that in an effort to protect themselves.
I second CanadianJim. Do not defoliate, and do not remove anymore bud sites as they appear.
The training should be accomplished in veg. Once in flower, let them do their thing. You can gently set aside a branch or three to allow more light, but stressing during flower is risky business.

 

[Rad Man]

Not sure if it is the light, but these pics make them look a light green. If that is true, another feeding is probably due.

Nitrogen toxicity is your issue back off the nitrogen during flower.

Your PH is off...yellow witch gnarled leaves...it's not getting any food

If you're growing in nothing but peat moss it may be that it's lowering the PH too much...peat moss is for lowering PH in otherwise acidic soils, and is recommended as an amendment "only" for soils or other grow mediums

 

[CanadianJim]

The only time I had a plant look anything like that she was underfed. I thought it was wind burn/heat stress too, until a more experienced grower set me right. A plant that large that has only been fed once? Unless you up-potted her a couple several times she's running low on nutes.

edit: a more experienced grower like Mocha, lol. He'll set you right.

N tox would show "dark green" leaves with that witch claw going on

 

[Rad Man]

@BeanTownFan420 Hey man, I'm a big fan of your grows, You do some pretty work!
I know nitrogen usage backs off during flower, but if he were in Nitrogen toxicity space, wouldn't the leaves be a dark(er) green?
I think they look wind burnt and hungry, but heh, I'm still new/learning...

 

[BeanTownFan420]

Those leaves a pretty green with some burn and curling.Toxicity is my guess.

 

[HigherTheHigh]

I'm with toxicity too, had a few plants light green in colour have really bad n tox situations.

 

[Rad Man]

@HeySam You can tell the difference between Nitrogen toxicity and wind burn by the clawing on the leaves.

If the damage is worse towards the fan side, you probably have a wind issue. If it general overall, Nitrogen may be a player.

After a closer inspection you may be correct bad lighting till I blew it up, it is kinda green looking...and he's got spider mites

 

[HeySam]

Yes theres a lot of clawing. The leaves are dark green but look bright under the light. But in normal day light theyre dark dark green

True i noticed that. And i sprayed her 10 days ago, no more mites under the leaves.
Your sharp noticing details

I am here to help as is every one else hope you get it corrected keep us updated good luck.
