Cal def ? Light burn !? Im lost. HELP !

[newbieAF]

Hi guys.

Im growing Gorilla punch auto from Fast buds in a 2 x 2 tent. Growing in autopot 5 gallon smart pot eith biotabs perfect plant in 50/50 light mix perlite. Temp 25 c ish and humidity a bit too high at 63 % . Got a Vipar spectre xs 1500 pro and running at aprox 45 dli. But i just found these brown spots and i dont know what to do.. first grow !

And our tap water here is about 20 dh.

I would really appreciate the help !

I'd supplement calcium and turn down the light.

Thanks bud, much appreciated . I'll feed it some calmag and raise the lights.

A picture of the whole plant would be helpful. Are these blemishes just in those spots? Looks like it might be some kind of septoria, imo.

Its only on 5 or six leaves.. would it be safe to remonce those leaves without stressing it at this point ?

And thanks ! It much appreciated !

Yeah, it'll be fine removing a few leaves here and there. If those were mine, I'd be removing more than a few. Especially inside, closer to the main stalk. Not going to be getting a lot of light in there, and it will improve airflow through the plant. What week of flower are they in, week 4, 5 or so?

Im just scared to take too much.. really dont want to stunt the plant and have to start over. That sounds about right, probably noticed the first white hairs about 24 days ago. It just finished the preflower stretch a few days ago..

You've got plenty of vegetation to remove some leaves, especially lower down and on the inside.

Thanks bud i'll do that.

I am just thinking out loud here...it looks very much like calcium def, but it could also be led light burn . and if its too close or too bright to cause burn it will also start locking nutrients out , plus coco holds onto calcium ,
ive got a xs 1500 (not the pro) and i got led burn once, it looks a bit like leopard spots if it goes on.

Those slightly turned up edges could lend to light burn spots, but honestly at this point you should already be giving them some kind of calcium…BUT….i wouldn’t stress and chase these little dots unless it gets worse than a few dots ha ha.

I remember chasing every blemish and every imperfection, but let me tell you this now…

You’ll always find some in some shape or form!

So don’t sweat the small stuff, and make sure you feed a well balanced diet of micros and not just macros!!!!

I see the similarities.. And with my yellow tips i think you might be on to something. I bought a lightray diffuser for my phone and was using that to check ppfd and dli and im just around 45 ish. But guess it might not be as precise as advertised. . Thanks bud

Its my first time growing anything, besiddes mushrooms and they pretty much grew themselfs. Just bought the biotabs because the concept seemd so simple. Prepare the soil and then only water from there on..

Just went and bought biobizz calmag, but im not really sure how to go about it. Do you think i can just add it to the water resevoir on the autopot system ?

I really appreciate you guys spending time to help me out. !

you could always foliar feed it with calmag ! then you dont risk overloading the roots with calcium and locking other things (nutrients) out...although you might be in one of those water systems, which ive never used. if you foliar feed it acts faster ....Im not an expert , ive just been reading up on it.

There's way more green there than there is brown. Leave the leaves on the plant. Your plant will move the nutrients if the leaves in question begin to die and recycle it to the rest of the plant.

The suggestion to add calmag is solid however to be quite honest with you, your plant looks pretty good. Those little brown spots are frequently caused by pH shift. As long as your plants are green like they are, I would not worry about it. Your plant is a living thing. I don't know anything living that is perfect. There will always be a blemish or 2 even on the healthiest of plants.

Your grow looks like its going pretty normal so far. Keep up the good work.

I agree with removing some leaves to improve airflow especially closer to the main stem. However, those leaves with the little brown spots don't need to be removed just because of those brown spots. I would remove those that are interfering with air flow ... especially the ones down low and close to the stem. Those tend to have their own more humid micro-climate and frequently don't get enough light.
