What Deficiency Is This? Phosphorus?

[Chrnic]

I gave my girl 0-10-10 Alaska Fish Bloom Booster a week ago and it looked like i burned her a little. So its hard for me to think its phosphorus. All effected leaves are at the bottom so its mobile.

I'm at the end of week 5 flower.
I cut Cal-mag last week.
I don't see any signs of pests.


What is this? Thanks for any help you can give me

What’s the run off ph like? Phos doesn’t really burn that way. Strange and now I’m intrigued as well to what the vast forum experience would say

6.5 PH runoff. I am in Soil
The burn I was referring to is the tips not the browning (Narcosis) you see in the pictures.
Thanks for the reply

Looks like she's shaving her legs for you if its only foliage at the bottom of the canopy where light doesn't penetrate. How moist does she get down there after a feed at lights off?

I keep the tent at 46-48% RH on avg
After watering it can get in the low 50's never above 55%

Everything under the trellis is lollypoped

What do you mean why Shaving her legs?

She's sucking thos leaves in the dark dry because they are unproductive and dropping them off. Might also be slightly overwatered with lower air movement under the canopy where humidity sticks and it's fungal.

Hmm, I have a oscillating fan under the canopy on high. Seems to be windy down there. The Narcosis seemed to happen fast. saw one or 2 a few days ago. Now alot, like 10-15 leaves.

Should I lower the RH?

 

[Chrnic]

On closer look there are alot more leaves like this. I just pulled off like 40. Seems like its moving up the plant but still lower down

 

[Chrnic]

This was taken with an camera jewelers loupe. I don't see spores but should I be able to with this picture? After seeing this could it still be fungus?

To be safe until you figure it out lowering the humidity is one thing that may control, if it is fungal.
But I think defoliation of all lower leaves should be in order to stop spread. Improves airflow. Sends all the nutrients top side. But I do hope it’s isnt blight: cause is looks like it but let’s be positive

How low should I take the Humidity? I put it at 45%. Is that low enough?

If it’s just on the bottom of plant on leaves not receiving a lot of light and it’s only happened SINCE putting that floor fan down there on high. It could be at least partially from the floor fan. If I turn of my floor fans before pruning them up really well I get a lot of dieing leaves down low that have big brown necrotic spots similar to P- . The leaves in shade lose their waxy cuticle which prevents dessication, you expose them to wind and they will dry out and die in short order. Might be your issue?

Are the plants healthy overall? You can’t see spores it is imposible with what you have. Those leaves don’t look good i hope you figure it out before it spreads further.

I also have 3 Clones on week 3 of veg. Clones came from the one in flower we have been talking about. They are attach by the same air system and I move a lot between both sides of the tent. They look very healthy. No problems at all.

I found springtails last week and wanted to dry out the soil a little. So i waited an extra day before watering and her leafs looked a little stressed after watering. Just a small droop. Today she looks much happier. I read that springtails are harmless but didn't want them to get out of control.

I lollypoped her pretty good. Everything under the trellis is gone. So yes its at the bottom but not that far down. Maybe tho

Check your roots bro sounds like it could be root rot esp if you have wet and dry soil and how its starting from the bottom upwards

im in soil, how do i check the roots? Also im in cloth pots

No bud damage I can see so far. Just removed alot more leafs. Was pulling leafs for days. Way more then I thought. None of the leafs on top have it but some are just below where light can barley get through.
