Just joined, first post, need some help please.

Hey there everyone, first time on the forum. First indoor grow for me. I am in a 3x3 tent, 6" passive vent opened at bottom (CO2 bag placed on ground at this vent as per ExHale CO2 bags confirmed), filter & exhaust fan hanging at top, Phantom CMH 315 light.

I am using autoflower from seed for this first grow so that I could set up for consistency and understand how to keep the temperatures/humidity where they need to be; basically dial in the tent to make sure I have the environment set up the proper way.

I topped two of the plants (one White Widow and other Trainwreck).

On the White Widow, for about 3 weeks now, I have been battling orange spots all over the leaves. I am not sure if they started at the bottom, but leaves all over the plant have them and I am about 30 days into flower on it. This means that a ton of the sugar leaves all over the plant are oranging out and becoming brittle. Over the past two weeks I have been clipping the leaves that had been heavily covered in the orange spots.
I also notice on the underside of the leaves that directly under an orange spot on top of the leaf a white spot is on the underside. So with a bunch of orange on the top, I have equal on the bottom in white.
No bugs are apparent, no webs.

This has not affected or "leaped" over to any of the other plants as they look beautiful without any spots on them at all (and its been 3 weeks with this issue on the WW plant)

Two thoughts from my reading:
a fungus I read about... nothing rubs off the leave to indicate this is the problem.
a calcium deficiency?

I went with a calcium deficiency diagnosis and have given appropriate dosage of cal-mag for the past two waterings. I see no difference with the plant and the leaves are continuing to show the orange spots, not going away...

Can any of you please take a look at the pictures and let me know:
-What you think/know the problem is
-Advice for remedy if even possible at this point
-Still smoke/vapable after trimming/drying if I just chop it now?

Id ride it out too.

Just for a joke tho , whats your humidity and temperature at?
Do you follow the vpd chart ?

Also whats your ph ?

Do you have fresh air coming in ? To put some actual co2 into your room.

Those bags are bullshit

Are you in coco?

Hey there, thanks for your reply.

Ph of feedings are always adjusted to
6-6.5.
Humidity is hovering at about 40/45%.
Temp is held at 74-76F.
High quality soil.
5 gallon fabric pots.
I have a 6" passive duct at bottom of tent open at all times and can feel the air coming in from there for sure with the exhaust sucking out the top.
Have a small 6 in fan blowing across top of plants as well.

Do you have any air exchange to the outside world for fresh air ?

Or are you just recycling your house air?
 
I am set up in a large garage. Air is exchanged when door is opened throughout the day however much that is?

I am not ported to outside through wall.

Unless you open that door a few times a day... Its time to start considering a 6 inch hole saw or a tank of co2.

Honeslty i prefer making a hole and put a dryer vent cap .

I agree with the other posters above, at this point it would be best to just ride them out until they're done. However, let's all try to learn a little in the meantime. It appears you're short on Ca...BUT...for my own curiosity, can you post pics of the bottom of your leaves in order to show "I also notice on the underside of the leaves that directly under an orange spot on top of the leaf a white spot is on the underside." these white spots you're noting?
 
Ok Thank you all. I appreciate your time for sure.

A question about hole in side of house for intake of fresh air. I am in the NE so what do you suggest for the deep fall and winter time for that cold air drawing into the tent and still trying to maintain temperature in a 3x3 like I am using?

Also CannaCountry, here are some images of individual leaves and undersides. Let me know your thoughts.

Thanks

Sobfor the vent , its going to have a vent cap so cold air doesnt blow in. I also use a damper for wood stoves it opens when the fan starts blowing and shut when the fan stops. Its just two flaps on a little spring simple fix.

And youll be exhausting your air not suckling air into your tent.


Fresh air will vaccuum ib little air holes in your garage like around your doors and windows vents anywheres theres a hole.

If your totally sealed up tight, youll findout quick lol .

Not many garages are air tight tho your probably fine.

Interesting pics; thank you. It appears you're short on Ca and from your original post it sounds like you made the necessary adjustments. What I wouldn't look for is for the leaves to repair themselves or go back to all green. The damage you see is going to be there until you bring them down. My suggestion would be to try and find a leaf that doesn't exhibit the symptoms you're having or find one leaf that you can take a pic of and then compare it each day to see if the issue is continuing or if you've stopped it. All in all though, I'd go back through my notes, try to find out where things went wrong (whether that's in your feed program, your soil, your pH, etc), make notes for your future grows and get your girls to the finish line as best you can. You're learning, we're learning and in the process we're all better growers for it; good luck.

6 pH is too low for soil; adjust to 6.5 for best results
 
Soil Type = Vermont Compost Company - Fort Light compost based potting soil (linked)

Always adjusted my tap (not RO) water's PH for watering.

As for nutrients, I was told with this soil and the short length of time for Autoflowering cannabis that I really didn't need the addition of nutrients.

That being said, since the issue with this one plant and the leaves I did go by a small container of cal-mag to try and help it as outlined in an above post.

After the first watering of 1/2 recommended dose per gallon from the container and a week going by with the cal-mag addition for that plant, I continued to see more leaves at the top (even up to the small sugars on flowers) developing the spots and becoming what i would consider brittle and dry.

When it came time for the next watering, I gave the full recommended dose of cal-mag and seeing the same issue, I came online for some help.

Please let me know polishpollack if there is any other information needed.

Thanks again.
