Spots on leaves

[jkz2023]

Hey guys first post. I'm on my first grow but have been having a few issues. On one of my plants there are a bunch of spots on the leaves and they're yellowish. Doesn't seem to be insects or anything. They're autos and on week 6. As you can see, they were a little stunted during veg. I'm using a vivosun vs2000 led and a kingled 1000 in a 4x4 tent. 18/6 light cycle. Ff ocean forest soil.

First indoor or first time growing? Looks like ya have a few things to dial in. What are your temps and humidity? Also, how are u watering them?
I would get that net out of your way as your plants dont need it.

Without more information, I'd say overwatering. Maybe during veg, the overwatering caused some root rot. Let her dry out a little more than what you usually do and perhaps top dress blood meal or worm castings.

Pretty much first time growing period. Temperatures are around 78-82 or so. Humidity 30-40%. I have the trellis for my other plants really.

Watering them from the top. I let them get a bit too dry during veg. There may have been a time I over watered as well. I'm not sure. I was having some trouble figuring out when to water at first but I've only watered when the top inch or two was dry.

They need food. Water in a good dose of veg and bloom nutrient base mixed 50/50. So half veg and half bloom. Plants are starving and consuming themselves.

That was what I was hoping to hear. I did actually do so last night. They do seem to be doing better already. I just wanted to make sure there were no other obvious issues.

Raise your humidity as well. Should be at least %45.

So first off I’ll say it’s easy to over/under water when ur first figuring everything out. Weight of the pots is pretty standard. Lift a dry pot of dirt and one that is soiled for reference.
Do not water until run off as u will be essentially flushing out all that good biology from your FFOF.
How droopy/wilted were the plants when u let them dry back?
I’ve definitely experienced similar looking issues and the root cause in my case was watering. It’ll make the plant show all sorts of issues from lockouts.
As for feeding soil I like top dressing with base soil, ewc, teas…
As for the trellis It’s hard to work around ur plants with that net that’s why I say that. If u need support on a couple plants use stakes or strings. If you wanna SCROG u want smaller squares in ur mesh.
One last thought is maybe try a couple less plants next time. I am still learning and feel with all my other chores I can only manage 2 indoors plants with my current setup. It’s easy to get excited about MJ.
Ok back to Spider-Man 2.
