First time grow - yellow spots

[GravitySlave]

First time grower and things have been going well until today.

I'm growing in Fax Farms Ocean soil 2 Barneys Farm Peyote Critical and 2 Lemon Drizzle.

I have been watering with plain tap water up until yesterday.

Yesterday I mix 4 gallons of tap water with 24 tsp of Big Bloom and 8 tsp of Grow Big.

I also topped the 2 Peyote Crits and pulled them over with pip cleaners for LST.

Today, my plants have yellow spots on one plant and yellowing leaves on another. (pics below)

Did I do something wrong?

So being someone who used fox farm.... cut your dosage in half... also look like light burn coupled with over feeding

 

[Cannaburg]

So if it says 6 tsp per gallonnonly use 3tsp

post better pictures of all plants.. something not good going on here..

nothing to do with feeding.,

Almost looks fungal, I do see a couple spots that also could be the beginning of wpm.

Then only use it every other watering, maybe skip one.

If white powdery mildew check this thread out... use milk...

Better scope them for pests

This looks like two separate issues... the yellowing on one plant and the spots on the other.

The yellowing of the leaves looks like something with watering/nutrients. Maybe ph.

The specks looks like it could be some type of fungus.

How far is light above plant and what kind?

 

[GravitySlave]

Thank you guys for all the tips. I thought it might be the light, (AC Infinity IONBOARD S33) I had to pull it all the way to the top to get at the plants and may have moved it too low (about 9 inches above the plants). I just logged into the controller and turned it down to 80% until I can get home at night to raise it up a bit.

I have been only watering about every three days and next time I'll cut back on the nutes to see if that make a difference. I need to get a meter to test the ppm of the runoff. I don't have to water as much because I have the fabric post sitting on the AC Infinity self watering fabric pot bases (https://www.amazon.com/gp/product/B0B1SL84RG/).

I'll also check with my scope if there are any funky things on the leaves (pests, fungus, etc.).

My light was too low by about 4 inches so that might have had something to do with it. The yellowing spots and tips appeared the morning after the feeding, and the one thing I noticed was that the leaves that have the yellowing seem to be the ones that I might have poured the water/nute mixture on and didn't rinse off. Could that cause this? I don't see any pests or fungus.

ok no spilled water won’t do that..
you issue is your watering habits mainly and probably your light a bit close, whatever you think the light should be raise it 5 more inches..

I was thinking the same thing once I saw the last picture. I have done the same thing now I just use the photone app because it gets me in the ballpark ppfd wise.

Thanks guys. I raised my light another 6 inches this morning.

Things are really taking off, surprised me how much 4 different plants (2 strains) grow at different rates. One of my indicas is going nuts (the one with the yellow spots). The other indica that looked like a freak early on is growing like a weed. The 2 sativas are growing slower, but looking great. Will be topping those tonight and pulling down the main stem like the other 2.

I got 4 different strains myself all harvesting at different times... my earliest is white widow and my latest will be great white shark.... blue dream and original glue somewhere inbetween

This how excessive light burn will look on plants
