What kind of damage is this?

[Boio_]

Hello cannabis aficionados!

I am once again back at it, with the same motivation that I began with and a heart full of joy that grows alongside the plant. However there is, as I'm a beginner still some damage to contend with. I have planted three new plants and they are doing quite well. Today the one that was winning in terms of growth started showing some damage and I am not sure whether it is a nutrient based one.

What does it look like to you? Any help is appreciated greatly!

Thrips, you can see them on the downside of the leaf with a microscope.
You run them under LED´s?

How to Get Rid of Thrips (4 Easy Steps)

@Alpenglow yes LED. I wonder how they got there...I live on the third floor and its winter.

Sorry for the double post. I have not been able to identify animals with my jewellers lens, is there anything else this could be?

You are using tap water and that's your problem.

Thrips are crazy stuff, if you once had them and couldn't get rid of it its time to clean the room multiple times. Im already thinking about burning my laptop to not get them from you

Your newer branches look like its too cold in your room/tent. What are the temps?

if your lens is lower x60 it would be hard to detect them. You can try to spot small black dots, thats the...

There is nothing wrong with using tap water as long as you adjust the pH.

It looks to me like the plant could use a feeding and proper pH adjustment. You are in soil so add some nutrients to a gallon of water and mix well. Then adjust pH to 6.5.

Alpenglow I see. I just wanna make sure now. This kind of damage is certainly Thrips? If so, do you think using Neem Oil will suffice? The other plant shows no signs yet. Temperature is 26°. I adjust the water to pH 6.5 when I water and recently started adding some BioBizz Bio Grow according to the feeding schedule. Right after starting the grow I realized a transplanting strategy would have been smarter, starting all the plants in the same tent and later moving to bigger pots and tent.

Thank you for you help!

Boio_ Never used Neem Oil, i had success with BAC Plant Vitality Plus and similar products. 26 is ok, not great but will work.
Check the PH as mentioned, let it grow for 2 weeks. If that doesnt help you can still think about Cal/Mag supplements when watering or do a spray solution as long they are in veg

I'd let it grow for a few weeks. Sometimes seedlings look like that when overwatered in nutrient rich soil. I always overwater my seedling in fear they will dry out before established.

I think it might pass. The uniform pattern doesn't suggest bugs, unless they are very artistic. That damaged leaf has the 'over grown' appearance of too much food. It was a while ago though, before the roots had spread out, and the compost had little use. Right now, I don't view it as much more than interesting. The next leaf up shows some similar but much improved signs. So much improved, I missed them until just now. At this stage I'm not going to start calling out possible deficiencies, as it's all too new to be correcting anything. I think it's just getting it's roots down still.

It's very small to be feeding it. Is the compost really that bad?

Tap water is modified to reduce the cation exchange to keep from leaching heavy metals into the drinking water. If you use tap water you will add a lot of hydroxyl molecules that block receptors. When you use acid to lower the pH there's a by-product that is produced and left in the root zone. Using tap water is using the lowest grade water one can use. Tap water will work but it's not the best water for organic soils.

You asked what the problem is and I told you, Tap water is adding too much calcium in the root zone.

f-e Hey, great to see you back in the council :'D I will do that, but be on the look out for those animals.

Creeperpark What do you suggest to do instead? Are there any methods I could use? I don't have much space.

@Alpenglow Thank you for the recommendation. I will observe it a little longer and decide on the method soon, if I can identify the bugs.

How are your temps?

You don't have bugs. The people who responded to you don't actually grow. It's obvious they don't. They all work for pesticide companies, nute companies and ph meter manufacturers.

You have micronutrient deficit. AKA "lime toxicity". Nute companies want you to flush and refertlize with more calcium. Ph companies want you to buy their meter and see your ph is too high. Pesticide companies want you to spray pesticides, because pests symptoms are, physically, boron issues, so they like to play dumb, aka overly cautious about problems that don't exist yet, and won't exist if you pay attention to nutrients instead of all the fluff of "growin weed".

The grow industry does not want growers knowing what micronutrient deficiency is. I want you to buy a 30 dollar jug of boron that will last you and all your friends a lifetime. Then we can all laugh at Dj Shorts Instagram together.

Get your trace minerals up. They are enzyme cofactors that bring the funk. Ants can't separate lipids carbs and boric acid. Aphids are a symptom of selenium deficiency. Etc etc. The magic bullet no one wants you to known about. Micronutrients.

You're literally being lied to by industry shills trying to warp your mind into what the past 30 years of indoor Cannabis have been: a circus of sick, expensive plants. It's 15 minerals. After visiting this site for 7 years, I'd say absolutely no one on this site is a legitimate grower except for the new users who get fed all the acronym salad and Amazon links.

It looks more like Beetle damage than Thrips. Thrips leave tiny yellow rasps and black soot from their excretions.

But it really doesn't look like bug damage. It looks like something scraped against those leaves when they were first forming. It's probably just cosmetic damage.

Just use pure water and if I ever need to buffer it I just use a tiny pinch of dolomite lime or add a little cal-mag mixed with the water. However, if the soil you are using is pre-mixed and has plenty of calcium then just add rainwater only. That way you will know exactly what your plants are getting. The favorite I have used for 50 years is Rainwater that hasn't touched the ground out of a rain barrow. In times of drought, I only use RO as a second choice. RO is super good for growing weed and the only other water I ever use.

I didn't ask you anything. I didn't read your post. My post was advice given to the OP. That is all.
