Leaves dying
Cannabisflakes
started grow question 6y ago
I removed these dying leaves, they were burned, with signs of necrosis and curling down. Now the plant siting next to the "sick" one started to show some early signs, similar to what her sister showed weeks ago 😪 Does anybody know what is going on?

Calmag problems usually caused by too much phosphorus. Bloom booster is a likely culprit.

I have some kind of deficiency but not sure what. I’ve flushed & hit her with some cal mag. It’s almost time to flush anyway, (day 45) is there more that I could do? She’s got some buds, maybe fine 🤷♂️

Spots on leaves, brown shimmering.
I've read that it's a boron deficiency, but I'd rather be sure.

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Brown spots and yellowing leaves.
I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.

The middle plant is somehow very bad off, while my other 2 plants seem fine, making me think its not humidity/nutrient related, but i really cant imagine what it would be, has anyone experienced this before? it went from perfectly fine to this in just 4 days.

Just to confirm, this looks like nute burn, doesn't it?
Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

I think I have nut issues?
OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

I found small spots (similar to rust spots) on the 2 ladies now. I saw something on the lower leaves. Can someone give me advice on what this could be or how I can get it under control so it doesn't spread further? Thanks in advance!

Hiyo. Plz notice the 10/30 pics. Should be about 4 more weeks to harvest. I know she is going to start going off as we get closer but this is a couple weeks early for my liking. Any ideas? I water/feed with the basic fox farm trio. With 4 weeks left is it an issue? Thx.
