Calcium Deficiency?
Ganja4Showstarted grow question 4y ago
Hello fellow growers.
some leaves are showing brown spots. I thought calium deficiency so started with adding Calmag to each watering. 0.7 ml/L
I still see some new leaves getting spots after couple of days.
could it be something else?

Lower your ph. 7 is at the top end., not where you want to be. 6.5 is much better for nitrogen uptake. Don't overdo the cal/mg. Very heavy in nitrogen. If you always add just add a little. Cheers

@ GMslave already ordered a bottle to lower the PH.. didn't have it yet so i can't act immediately but hopefully in 2 days i can. Thank you for providing me an answer. will leave this question open a bit longer though.

Leaf Septoria?Can almost see the end in sight on my first grow, and I think I have a problem. Noticed a few lower leaves weeks back with spots, so I removed them and kept cleaning the bottom of the tent, but I think it’s spreading. Is this bad enough to worry about end result?

Is this self topping ?I've just noticed that my Lemon OG auto has no top, I'm guessing this is what self topping is. I've heard about it before but never experienced it. Have any of you encountered this before and what are your thoughts on it, is it beneficial or a disadvantage.

Advice?Done with LST. I added a little overdrive.. just so anxious. My plants seem in line with pics from other Growers diaries. Any advice appreciated. Sometimes I’m afraid I overdo it with early topping and I did a lot of lst on these. I’m new at this. Thanks for reading! 🌱

Minor discoloration on seedlings (nitrogen toxicity?)If anyone has advice on the middle plant, I'd hugely appreciate it. I added nutrients last Thursday (7 days ago) and I am pretty sure it was way too early. The middle plant has some discoloration on the leaves. Will avoid any more nutes until I transplant into 5 gallon smartpots.

white spots on main leafI just saw that she has some white spots on her main leaf (this one only has one main leaf),
Anyone can identify what that might be?
I should mention that yesterday when I woke up she was fallen down on the soil because of some unusual strong wind in the night.

What's going on with this leaf? Changed colors overnight?Woke up to find this leaf in the back of my tent. What's going on here? Day 46 flower. Recommended flowering of 60-70 days. Looking at my timeline, I figured I had maybe 1 or 2 more feedings left before I started giving just water till the end. Should I worry or is this normal?

Yellow leaf septoria?Hi, I think some of my plants have yellow leaf septoria. How best to treat this? Should I consider removing leaves, plants or maybe starting again.
It might of been due to my constant misting to maintain a high humidity at the start or I was also thinking fungus gnats
