Spots on the leaves
cpavanstarted grow question 6y ago
Hello guys,
I noticed some spots on the leaves from one of my plants. As I’m a new grower, I don’t have any idea about what is it. Could you guys help me with this?

Hey buddy! This is the start of a phosphorus deficiency! Spots on the leaves, red stems! 👆
Solution to the problem:
1. Set the appropriate pH of your substrate. If it's coco + a mix of perlite, etc., then it's considered hydroponics and you need the pH for hydroponics! Set the watering acidity to 5.7-5.8 pH 👌 👆 If you have soil - 6.3-6.4 pH. 👌 👆
2. Adjust the nutrients: grow:bloom ratio 1:4
If you're using micro nutrients, then don't add "grow" at all!
Bloom - 4ml/l
Micro - 1ml/l or grow 1ml/l 👆
Good luck, buddy! Stay healthy, wishing you growth! ✊ 😇

hi there.. without knowing any more about your environment and feeding-habit, i would say it's a nutrient deficiency.. the dark necrotic spots could be due to a calcium deficiency.. the yellowing could be magnesium or nitrogen (if on older leaves).
what is your feeding schedule and how much (and what's your growing medium? soil? coco? peat?)

* Spots (pic 4), on only 3 leaves of the plant at the top.
Last week, before lights out, I misted. By lights-on time, some parts of the plant were still wet. Is this some water burn?
Tap water is PHd and ~215 ppm (plenty ca/mg)
* Any insight on those yellow tips is welcome! :)Week 6

Big disseaseI think i have nutrient lock out but don’t know how to fix it it, its 3th week of bloom and its an outside plant. Its getting colder 9 degrees C at night and around 20 at day. Its been raining a lot recently maybe that has something to do with it.

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've been having this problem with the browning leaves on the bottom.
1. Every time i do DWC from seed, the picture as shown on Week#2 Day#11 happens. Why is that?
2. What do you think is causing the browned lower leaves? Is it calcium deficiency? Or potassium?Week 3

Leaf problemsMy leaves are getting yellow from the bottom, and some have burnt tips. It started when she is in flower.
I often feed Powder Feeding from Green House. PK+ (NPK: 0-30-27) and Hybrids (NPK: 15-7-22) the PH is 6.5
They say this strain wont need much nutrients but can handle more

Bottom leafs getting dryThe last two pictures show some sights of deficiency after getting a little bit dry before repotting. Any recommendations: should I do something? I will definitely use some ph-down and water with 6.0 to 6.5 ph to help the microorganism get going :)

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍

Dry yellow tipsI've noticed a few leaves have developed some dry tips on the ends including some of the new ones coming through. Can anyone tell me what could be the problem? Feeding bio grow 2ml per l at the minute. Is it a deficiency of some sort? Or nutrient burn? Worth sticking to water?
