Yellow leaves flowering week 3-5

[420jpboy]

Hi I have a question why my plants leaves turn yellow?

The Video is on 4th week of flowering.
First picture is on 3rd week of flowering.
Last 2 pictures is on 5th week of flowering.

I’m using Flolaflex 650w light, and it hangs 17 inch above from canopy it around 65000- 70000 lux.

I’m using advanced nutrients sensi bloom master grower formulation.

I’m using rockwool 6x6 block once a day watering.

When I check Ph it sits between 5.5-5.7
Roots runoff water is 5.8

Room temp is 80f when lights on 73f when lights off.

Co2 level is around 800ppm.

Humidity is around 50%

If you need more information. Let me know.

Too much light for too long.
They fried.

Those lights can be easily hang at 3feet+ from the plants without any problem. (Between 60-80% intensity), depending on age and size.
With CO2 at 1200ppm in flower you could be using 100% at 2 feet maybe less with everything dialed in.

I would start flowering at 1.2m from canopy @60% let them finish stretch ~3 weeks than push lights to 80% and slowly lower it to 60cm over the course of one or two weeks.

Quite. Indeed, yes, I concur. The curly shuffle.

I'm doing what you suggested to me, and my plants look much healthier than the last grow. I hope I do not burn my plants until the harvest. Thank you very much.

Too much light is a common issue, just learn and improve. Most of us have cooked a plant before ✌

I'll be careful about the height of light more. Thank you!
