Is this normal?

[Mooregrow]

I haven’t found much clarity online but il let the pics do most the talking

13 week old northern lights autos
Had to chop one down as it was to big for the tent and weeks behind these, was over 150cm not including the pot

anyway 3 left and the last few weeks leafs where falling of turning lime green ect so I thought n deficiencies ??

but it’s cartied on and the fan leaves mainly are just dying now. More and more every day iv even got fed up of picking them up.

I feel like they have a while yet to go but there dying faster and faster every day

that pic of the pile of leafs is like the 5th!

@St. Tom hello
Mate sorry to tag you, any ideas? Is that normal, I was thinking tall autos so light mite not penetrate that low or that plant is absorbing nuts from the leafs?

i did look before and from what i could tell i would say your lights aren't penetrating to the bottom as you thought as i get this not as much as yours though also is all your top growth fine and any new growth as your plants look lush and healthy besides that but i will tag my good mate @arty zan in he's like a book of knowledge on tons of plant matters and he's one of my 1st port of calls if i have any worries

Thanks a lot bro. Yeah top growth and new leafs are fine, I just felt it was working it’s way up. I’m using a full spectrum led, and a hlg quantum bored. In a 150cm x 150cm tent 160cm tall, total actual watts it’s about 260/270

Problem: dying ?

Medium/grow method: coco

Feed: and supplements used: canna coco full range. Dosage is still at half of what’s on the bottle, iv have adjusted to see how much they take without getting nute burn.

water source: ph 5.8 in veg and 6.0 in flower

Strain/age: northern lights auto 13weeks

light used: full spectrum led 600w.. actual watts probably about 120 and hlg quantum board 150w

Climate: humidity and temperature does very depending on the weather it’s very hard in my situation to keep it consistent. At the moment it’s like 24c at night and 29/30c in the day but there’s been a heatwave recently, other than that I try keep it around 22c

Additional info: they have taken a lot longer than I ever anticipated and grown a lot bigger from what I have read Online. As stated one plant was weeks behind and was curling round the top of the tent

..lowers look like P defc wasting, maybe from the light feeds,... Do you have a PK booster?

Have you calibrated your ph probe lately? How often are you watering/feeding? Do you feed with every watering?
