First off welcome to Iglm forum
A picture of the whole plant would be best and maybe fill out a support ticket
but start with answering these questions
Type of grow indoor or out
Soil type
Ph water in
Nutrients type ? are you feeding ? if so how much ?
It is normal as a plant grows that some of the leaves
Especially down low in canopy that don’t get enough light will die off
Not sure if that what your seeing
Answer the above questions and post pictures of the whole plant
And we can help you to a harvest 
@Jasonaust
Thanks for the quick response country
Outdoor in the high desert 100 + degrees but in a shade structure
Soil in ground amended sandy
Water PH 6 to 6.3
They have only been getting tiger bloom twice a week
They are in week 2 of flower
100 º + is way too hot isn’t it ???
Back off on nutes and just ph water her keep soil moist not wet in that heat to keep roots cool and shade at the hieght of heat is a good thing
Not much you can do about temps in the desert outdoors @JedSanders
@Jasonaust but I believe your over feeding looking at the last two pics
Can’t Check ppm or ph in ground lol with out doing a slurry test on soil
@Majiktoker grows ingound in the desert I believe as well so maybe he’d be better to talk since your both in similar climates
I’m in the NE so heat and humidity are much different here
Your ph needs to be raised to 6.8
