The light is to far away. You have a dimmer so you can put the light closer and run it with less power.

Wondering if doing another defoliatation would direct more focus to the main sites? Also I have three other plants that are about 2.5 weeks younger, so I have to keep an 18/6 light schedule. Would I have to switch the flowering plant to 12/12 even though it's an auto?

NEED MORE LIGHT!
So as of right now I have 1 400w mh/hps light in a 4x4x6.5 tent. I know for a FACT that I can have way more light inside this tent. But my question to you guys is what kind of light do you think I should put in with my hps? Would like to have around 1000w or equivalent in PAR

IR cameras and ligth
Are IR cameras dangerous for the night cycle? I have my plants on streaming and I'm thinking of placing an infrared camera and IR LED I'm worried that the IR light can stress the plants and interrupt the night cycle. Wave you experience this with security cameras?

Leaves up?
Hey Guys 👍🏻 Quick question, I have my light (HPS - 250w) 40 cm above the plants - should I get the light lower? One of my babies has the leaves going up. I guess she is enjoying the light but I have doubts regarding the light distance.

How to grow Jack Herer and Power Plant strains
Hey growmies, I’ve started two Jack Herer fems and a Power Plant fem on my 3-D’s diary. I’ve read JH can be a mofo and should be grown on a 12/12 light cycle from seed. I read the same for PP also. Is this true???? I’m trying to maximize yield. Thoughts please… 🤯

Maximum
I have the LM-3100 Light Meter app on my iPhone using a piece of paper to diffuse like it instructs but I am not sure what the optimal Lux/FC should be. Specifically for LED lights, it is confusing. I have a viaspectra P2590z what’s the max/optimal light?

Light and water
Thank you guys! for watering, I don't know how she can react giving her more than 250ml. I can try but I don't want to drown her. For the light, unfortunately direct sun light arrives from 11.30/12 am to 7pm. Before it is covered by other buildings behind my terrace.

Grow lights
Does this look ok? I have 2 plants not growing as fast as my macchiato plant. The other two are different strains, Runtz & Zittles. I don’t want to over do it but I know light is key so I thought I’d ask. Both 1000 watt uv & the other is led. I’m on veg week 5 of all 3.
