Is this light burn?I am pretty sure it is led light scald but just thought id try to verify. I have a new 650w Hortibloom light bar and have been running it between 400w and 650w at the top of the tent.
I'm guessing 650w, even at the top... is too much?

Deficiency?Hey everybody,
I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors.
Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos.
Please let me know, thanks!Leaves. Edges burnt

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?
It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)6y ago

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?Leaves. Edges burnt

Leaves curl on upper new growth and mid but not lower.I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.Leaves. Curl up
