Spots have progressed

Brown/ orange spots appeared on my leaves yesterday and I can’t seem to figure out why. My water ph is 6.2

I’ve been watering with cal mag for its recommended amount

The last watering was just fish sh!t and cal mag because I noticed nitrogen toxicity as well

I’m wondering if watering stained the leaves or what because I’m not sure what’s going on. I did increase lights a couple of days ago to their proper PPFD which was about double what it was prior. I am about to hit flower so I wanted to try to remedy this to prevent too much stunting/poor growth.

This is two separate plants but both experiencing the same thing at different scales

One plant



The other

My first official grow and I’m experiencing this so I figured anyone with a couple of grows could point me in some direction. Please and thank you :smiley:

Looks like an old fan leaf. I think your plants are fine.

My concern is it’s two separate plants showing the same thing at the same time. One is 23 days old the other is 26 days but if you’re saying it’s nothing I’ll try to let it be. Thanks man

It is common for the lower leaves to develop significant blemishes. They will eventually fall off.

New growth looks ok, did you check runoff numbers?

Seems like a lack of something or to much. I found in all my grows plant leaveas rarely discolor or die just because. Its usually a result of imbalance of noots or ph. The curling downward of the leavs at the top i think also is telling you something is off. I would definitely keep an eye on it without trying to chase the issue with noots or ect. I would not use box store soil as its usually left outside and soaking wet. Definitely should test runoff. I wish there was a way to know forsure but that growing for ya.

Have not checked run off yet, but I’m debating doing a heavy watering next time. That way I can test it and possibly balance out the ph, but I’m not certain on balancing part.

I’ve been using craft blend from buildasoil as a top dressing. I believe I did that once and then got ambitious seeing pre flower and watered with build a bloom. I did notice the nitrogen toxicity thankfully and probably won’t give anymore nutes seeing as it’s a large pot and an auto. I appreciate the response I can start looking somewhere else now.

Yeah Midwest said that as well but they’re so young and I removed bottom two nodes of the larger plant. Which led me to believe my issue was when I watered, just hurts to see right before my first plant flowering :smiling_face_with_tear:

It is normal and you can expect it in grows going forward as well.

I’d still check your runoff numbers. They should always be managed properly.

Thank you bro, without this site I would lose my mind googling stuff.

Doc has it correct. New growth is good. If using a complete top dress nutrient line follow their directions to the letter. They built it for their recommendations. Added nutrients will make the soil hot. Unlike liquid nutes a top dress dry ammendment will take a few days to a week to really start breaking down and be usable by the plant.

I think I messed up by doing a watering of build a bloom, could’ve made the ph go up. I was over ambitious when I hit pre flower and remembered the two week thing forgetting that was in regards to dry amendments. Luckily it was only half strength but still enough to give the nitrogen toxicity. This is an auto is it best to just leave “bad” leaves to die in their own accord or remove them?

Actually, many growers strip the bottom 1/3 of a plant early in flower. Lower portions of plants never produce much anyway.

Hope this isn’t a dumb question but is pre flower considered early flower or once I start seeing the “hedgehogs” is considered early flowering? @MidwestGuy

Flowering is indicated by “hedgehogs” at the tips of the plant. If growing indoors, the hedgehogs will appear a week to 10 days after the flip.

All preflower refers to is a plant that is sexually mature but has not flowered yet.

There aren’t any dumb questions. Every one of us had the very same questions you have when we 1st started.

For autos as well?

Auto will go straight into flower once sexually mature. “Preflower” is more relevant for photos.
