Alot of leaves curling up and dying on bottom, but top is healthy wtf

[Alec420]

leafs dying but don't know what or why its happening
almost all leafs that are dying in my tent(these plants are not the only ones) are out of range of the 600 watt "penetration" which is 3 feet
But i don't want to draw conclusions yet.
Coco 2 gal
feed GH Nova Flora, cal-mag, sometimes silica. every watering
the plants did not really show signs of nut burn, because these leafs are just flat out dying right away.
6 weeks in flower

The way the leaves are curling and the amount of single leaves you have maybe an indication of being root bound...... or maybe reversing back to a vegetative state ?

kinda looks like N tox and re-vegging

well, the N tox is specific to these certain plants and the revegging.
it might be root bound though...

 

[R1b3n4]

Shouldnt be rootbound if its in coco, lots of people on this site growing a lot larger plants in same size or smaller plants without issues etc

 

[Alec420]

thats what im thinking!! So my other theory is they are dying because my canopy is too thick for light to pass, so the plants are killing the leaves for efficiency since they are not collecting any energy

these plants i took pictures of were monster cropped, so they look worse every time I clone them

Personally I would scrap those and start again.

Im with you buddy, but I have BIGGER plants that are flowering. I NEED them to survive lol

 

[Growdict]

Are these plants in a dark environment for 12 plus hours every day? Do any of your flowering plants grow any buds? What is the ppm and ph of intake and runoff?

Looks like powdery mildew on the leaf in the 2nd picture, bottom left hand corner of picture, so probably gonna come down to some kind of overwatering/rot/fungus issue I reckon

 

[Alec420]

these plants in particular were in the dark for half of flower. so Yes, the bigger plants tho have light all the time, well at least three feet of the bigger plants hah.
yes they are all growing bud sites slowly but surely. some of them have been drinking water fast. But these plants have not(in the picture) maybe because they don't get as much light.
I always try to have my Ph 6.1-6.5 and ppm has usually been 1200-1300.
I always have run off every watering, which is drianed out.
Ive once had run of though that was 2500 ppm. Does that mean the plants aren't eating?

thats interesting, it might be rot. My temps at night go down to 61, and somtimes I water at night.
I have fans on 24/7 btw
There is little to no powdery mildow on these plants nor my other ones
I Spray a anti mold solution once every 2 weeks

 

[Growdict]

I dont understand. Are these autos? These are sick plants. Lots going wrong here. What is it you are not saying? Not in a light proof room? Temps hit 90 plus sometimes? Bugs? Humidity? Ph and ppm are both high imo. Plants have been doing poorly for a long time it looks like

 

[Alec420]

I just took one out of its pot I transplanted in, Roots were healthy looking, white, soft. but not huge.
Only thing was the roots did not loose its shape it had when I transplanted it. they didn't fill in the new pot!!
temps never hit 90. Its usually 75-81, 81 is the highest its been for awhile. RH is 37-50, 37 RN
I spray anti bug solution 1 a week, however there are thrips around. Its always been a problem for me.
The plants were doing great until they got covered but the dense tall canopy
OH these are not autos

Woah if your run off is like 2500ppm then that could mean a salt build up right? Do a low ppm leach and make sure your PH meter is calibrated and ph it and see if they improve. Hopefully they recover !

It might be something as simple as this haha.
I really hope so because thats fixable

 

[Alec420]

here are more photos of this grave yard I have to look at. notice the darkness
I will now Low my volume of Nutes and still keep the frequency of watering's. Time will tell if this works
The bud sites look better than before which is strange

 

[Alec420]

update I found fungus gnats

 

[vapesCHRONICally]

Looks like bad N tox
