Seeing some top bud leaf discoloration
aRecreationaliststarted grow question 5 years ago
Starting to see small dark/black discolorations on the leaves.
Since I don't know the genetics, I can't tell if it's prone to dark leaves.
Could it be signs of anything else?
Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity

Yes it could be genetics but it looks like molybdenum deficiency.
It is often caused by low temps and excess sulphur. It should be nothing to worry about tho!

Do those leaves look a little too dark green and slightly waxy? May have to lay off the nitrogen I think.Week 12

N tox in full swing. Lowered feeding from 1 Tsp to 3/4 Tsp Cal/Mag, and Grow/Micro from 1/2 Tsp each to 1/4 Tsp each. Hoping this helps correct.
Is it possible that overwatering also contributed to excessive N uptake? I let the coco dry out a lot more (~4 days) this time.Week 4

Hi Growers, my tent has recently hit some low temps at about 15 degrees lights off, I have now improved the temps by a few degrees to about 17 at lights off. Purple is showing on my stems probably caused by cold but purple also showing on the back of leaves? Should I worry?Week 3

Is the Durban Poison doing alright? The leaves are quite dark compared to the other varieties. My guess it's either a difference in the variety, or a nutrient issues.Week 2

2 part question about harvest and flushing. I read that if most leaves around buds are turning color (purple in my case) you need to harvest soon before plant dies, is that accurate? If so my runoff is still the color of an ale after 3 weeks of flushing, is that normal or bad?Week 15

Today I noticed 🍄mushrooms popping up with GiSCele. Does that matter? Are they🍄poisonous to girlies? Don’t bother me,but I dunno🤔. I recently started using 🦇 bat guano and have a feeling that’s what encouraged- kinda cool if I see Smurfette sunbathing on 👙🆒👍🏼Week 20

Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?Week 5

Purple Leaves RQS Organic GrowHi everyone.
This is my first fully RQS organic grow. So not sure normal or not.No cal mag used only organic fertilisers from RQS Organic Easy Boost and Easy Combo Booster Tablets.
I have some purpling on the leaves?
Is it normal for Organic grows?
Or it's Calcium deficiency?Leaves. Color - Dark-purple
