Is this the beginning of a deficiency?

[4saken]

Hey guys
Growing one white widow mother out right now, got her under a 600w mh after the hps bulb burned out.

Shes on day ~35, and some of her lower leaves and middle leaves are starting to lose their color.

I just nuted her right after that picture, I give a cocktail every 3rd watering, so the schedule she is on is going like this:
water
water
2tsp tiger bloom/ 1/4tsp beastie bloomz 1tbsp big bloom

We try to PH correct as close as we can using drops and the color bar. Temps hover around 80* and humidity 40-50%.

She has been loving everything up until now. I don't want to keep nuting her untill I'm sure it's not nute burn, but I wouldn't think so considering the schedule.

Here's a pic, sorry for the crappy quality used my cell phone:

Thanks guys

i would give her some more N ... but i think you can use more nutrients on her anyways - accept of that a real beauty!

I wouldn't give more N.
For now just stay the course with the bloom nutes at this point.
Maybe pull the light away some too.
What medium are you running and what's the run-off pH ?
Are you keeping the air moving and exhausting during the night cycles ?
Do you find her looking pretty wet when the lights first come on ?
You might consider thinning out some of the bigger fan leaves that aren't getting much light and blocking good airflow.
What kind of tent is she in ?

The light is a decent amount away, we have to keep pulling it higher cause she's growing so quickly.

Sadly, theres no ventilation, just a few box fans around the room, which is approx 7x7 feet or so.We just purchased a cool tube for the HPS and will be putting that together shortly.

That's probably a good idea about the fan leaves, shes a monstrous bush.

I just re-checked the fox farm schedule, and it looks like they recommend throwing in some grow big on weeks 3 and 4, which we haven't done. Maybe thats the lack of N?

I also hear white widow is a notorious small eater, so maybe they aren't deficiencies?

Thanks guys

Here's some update pictures guys, it doesn't seem like its getting any better, this was the day after nuting her again following the FF schedule:

Thinking it might be a magnesium def...so watering with epsom salts today. I'll keep it updated if anyones interested

 

[Mr.Jones]

its always interessting how problems are solved - but that looks like the plant is screaming for more N - lock out or deficiency ...

still i would answer all the q's of 10k ...
