[Greengrower87]

Ok guys let's see what we can find out I have 5 girls in veg all are doing good but one I have had my eye on her she started with tiny brown spots then they grew larger and tops and sides started turning brown on my fan leaves also not at the bottem more in the middle to top I have another plant this as well this has been going on for 3 to 4 weeks and I still can find out what is going on so any help would be very much appreciated I will attach as many pics as I can also I'm running 18 on 6 off.

Did you try giving her a shot of Cal Mag?

Medium they're growing in?

Ph? Both water / feeds and medium.

I had a few of these symptoms this grow into my 2nd week of veg I didn't know what it was and still never found out .. but I fed them twice with just pH balanced water and they bounced right back then I toned down my nutes down a bit .. someone on here might be able to pin point the exact problem for you though

Growing in fox farm ocean blend and yes I ph the water and feed just did the medium. At first I thought it was a fungus but it's not spreading and the plant is doing well just some leaves are not and it starts very slow

What ph is it?

Have you been feeding nutrient as well?

How much, how often?

Watering schedule?

 

[Werp]

How much cal/mag. You could have excess cal/mag problems.

Yeah, i'd just stick to the water for now. I wouldn't worry about ph adjustment, ph7 should be fine.

Couple things.

Your feeding heavy P... Just so you know. My money is in this area.

You say you gave it calmag? How much and when/how often? Molasses has calcium, you could have locked out, but I doubt it unless you overdid your calmag.

I don't know what black gold is... It's compost where I come from, but we don't do it by the tsp lol.

If it's between 6.5 and 7.5, no i wouldn't bother.

Here is what black gold is. So as for right now just water and see if it clears up? Like I said the one it's really beating on the bigger fan leaves and i have another plant with just the small spots on it now i attached the pics and as for cal mag when I first saw the problem I hit them all with a 1/8 tsp into 1 gallon of water nothing crazy just has me bumbed and lost thanks everyone for the help trying to find out what this is. Anyone here think is a disease or fungus?

 

[3rd Monkey]

Here's what I would do. Next watering, 1/2 strength dose of calmag, nothing else.

I haven't known it to go bad, but I don't know.

What is the ec of your regular Sunday fertilizing?

tiger bloom 1/4 tsp along with black gold 1/8 tsp molasses 1/8 tsp

Teaspoons right? That’s really weak.
If my math is correct a 1/4 tsp(teaspoon) is 8-32-16 PPM N-P-K in the Tiger bloom plus the other stuff. If that is the case, how long have you been at this level?
