Deficiencies Again...Ugh

[I'm negan]

Last year all I had to do was water with tap and I was golden up till about week 6/7. Then I dealt with a slight deficiency. Nothing like this damn mess. Treated this grow same as last year. Not a clue wtf changed other than feeding bsm water and using mykos. If anything, the environment has become better.

The leaves look dry to me. How do they feel? Crispy at all? I can see some curling downward. I would try to run a humidifier in there for a day and he if they don't look a little healthier.

Which leaves? Some do, some don't. The ones with what appears to be phosphorus issues (brown/grey lesions) feel crispy and are curled upward at the tip.

I live in high desert. It's a super dry environment and I have been running a humidifier. Should I be going beyond 45RH?

So, I am having issues. No surprise there.

FF Soil
FF Nutes
Week 4/5 flower
No tools to test PPM or EC
No flush as of yet

1/2 dose through late veg & transplant upto the week before last. This was done every other watering. W, F, W, F etc with the plain watering containing 1tbsp/gal bsm & 1tsp Mykos

Full dose last week of both Cal/Mag & Tiger Bloom. (She was deficient before transplant which is why I was still feeding cal/mag in hopes to have a reserve in the soil)

Due for a feeding today.

No flushing has been done. Just watered to a slight runoff.

Stuck with an arrangement of deficiencies I am almost positive that I caused. Perhaps they are just heavy feeders???

Any help would be appreciated as well as criticism, cat pics and back talk.

My question to you is, "what did I f up & how do I fix it?" I'm at a loss here and don't want to lose my harvest.

What is bsm?

I'd suggest ditching the bottles next time.
Instead of you giving them what you think they need, give them soil with EVERYTHING and let them decide what they need. This is oversimplified yes, but I hope you get the jist.

Black Strap Molasses

Black Strap Molasses

Molasses can lower ph by the way.

Molasses can raise ph by the way.

In the time I have been using it I have never seen a rise in water PH after adding bsm. Still the same ol 7.4-7.6

Are you talking about soil ph changing due to increased microbial activity?

Im fried rn i meant to say it lowers ph. Its mildly acidic from my understanding.

Calcium deficiency is the most over diagnosed problem lol. Calcium is an immobile nutrient. That means it will first appear in the very newest growth. There is no deficiency that I'm aware of that causes those brown spots on older leaves like that. In my opinion it is blight. Either from disease/pathogen/fungus/insect. Also there is some clear nutrient deficiency that you would expect in older growth such as magnesium and phosphorus.

Read closer I never said Calcium deficiency.

Never said you did. The OP suggested it himself.

I don't trust those meters much tbh. I just try to make sure in feels nice and muggy when i open my tent, like walking into a green house. I had some downward curling like that myself and it was gone 24 hours after i added my humidifier. The trick was also putting the fan on a thermostat switch. So you're not constantly exhausting all the moisture, but it still kicks on often enough that its not raining inside your tent/room.

@I'm negan I try to push her upto 50% but my shotbox of a tower humidifier is only capable of holding upto 50%. Filters are new but the system sucks anus. Only half of the filter is ever wet so I'm constantly flipping the filter trying to keep even moisture. My old one crapped out on me but worked like a charm upto about 70-75RH while she was running.

As for how it feels...air is thick, slightly humid but not like jungle humid. I don't know how else to relay RH to you in a way that makes sense outside of that and digital meter readouts. I have 2 in the room. One 3 inches above soil and one at canopy. The canopy is just one of those small hygrometers that you can see in the original post and an Accurite below.

Anyhow, I've already taken the suggestion of feeding more and we will see what happens with that over this week.

I appreciate the help peeps! I just gotta stay calm or I'm gonna lose my shit. I need this harvest as it is my medicine. Being broke a.f. because I tried working an honest life and damaged myself to the point I can't physically work sucks nuts. You all helping really does mean the world to me. Thank you.

@Cannabinoid Froyd

Check this out. I literally just found this lying around the house but this little fucker is awesome. Only issue i have is the tank is too small and i have to refill it at least every day. Id like to modify it to take a 2 liter bottle as well in the top. But that's straight fog coming out not mist and it cold vapor too, idk how it works.... kinda blows my mind lol. Anyway i run this in my 2x4 and its raining inside within a half hour if the fan doesn't kick on. Not bad for $40. Link below



Crane Humidifier

locked out. when soil is dry again, give water with 30-50% runoff. when that drys out, give them a low feed, around 1ec, with runoff.

always need runoff to flush out excess salts, and dont let pots sit in it

Now about the pistils...

This is day 36 of flower. Pistils are turning color already, why? These are photperiod plants. I wasn't expecting any change in color until end of week 6.

 

[I'm negan]

I see a lot a burnt tips...So you're probably over feeding but idk if that's related... I've seen them turn early before from what i was told your good as long as new white ones keep forming.

Fucking great. I have noticed some gnats or Flys at the soil level. Overwatering?

Those gnats can be very annoying and stress the plant out even if it's well established plant.
There is some stuff u can pour to try get rid of the larvae, but most important thing to keep them away/and even get rid of them
is to let the top soil dry out, which is where the larvae and eggs are. Also take care if there is holes in the bottom where they can access wet soil.

So just to make sure, when you are watering do you check how heavy the container is?
I mean the gnat problem could really use few more days between waterings.

I noticed the gnats a few days after watering to complete saturation. And like 2 maybe 3 I saw across all 4 ladies. Otherwise I have been watering when containers are substantially lighter and with my usual 1/4-3/8 of a gal to each one.

Edit: Been trying to let the top soil dry more than an inch down and feel the weep holes for excess moisture before watering.

I'm not a soil guy, but don't most people let soil go almost bone dry between watering? Else your roots will not get oxygen i thought.

It's more of a balance on how much moisture a container can hold without depriving it from nutrients/oxygen (from being too wet).

Like too much drainage and there is plenty oxygen and virtually no way you could overwater, but then again it dries up too fast.
But then again, too soggy composition that soaks up all the water, now you got no oxygen before it dries out.
