Hey ThirdUncle
Nice to see you here. I don‘t think that it has something to do with light. Running it a lil above 50% with 30cm distance to the canopy…you might be right on too much nutrient cause the soil a used in my seedling container was prefertilised
Thank you Azi. Thought it has something to do with nutrient….should i counterattack it somehow? Anything i should look out for?The claw and dark green is often a sign of top much N, but the newer leaves look fine. Those lowers likely won't fix themselves so you'll have a reminder of what once was in your grow.
I'll bet it has something to do with your water. Check out the Chart for what clues to watch for.
In organics, slightly burnt tips mean they're getting just a little bit more than they need, but if it doesn't get much worse you're likely fine.Grapefruit Superstar also shows slightly burned tips, which i overall take as a good sign for the sonnenerde soil being loaded with good stuff.
Thank you Azi for that Chart
It is bookmarked. I also already did lil catch up on the thread (on page 6 of 230+ 
) Great stuff. Always loved the science part about growing. 
Like I said earlier. Not trying to play with big boys here. But I‘m eager to learn. What do you think? Would a excess of Mag show those signs? I remember the Mulder Chart where Mag and Nitrogen synergize, if I‘m correct. May this be why we see signs of nitrogen excess on the older fan leaves? But if so, enough Cal should be present, right? Otherwise the Mag would lock the nitrogen and we would see a deficit, if I understood @Gee64 right (and honestly I’m not sure, cause I had to read it at least twice just to be sure that we still talk about weed not rocket science 
Good stuff though )
Hey BCThank you Azi for that Chart
My water? Pretty sure, if this is your bet.
Yeah! Another expert on this journalHey BC
I would start by scoping those leaves with a magnifier. That may be bugs.
I'm no expert on bugs, I try hard to avoid them.
Look at the tops and bottoms for webbing and such.
Are you using living soil or synthetics?
Compost is living soil, it's loaded with microbes. It sounds like a good mix. Do you have any carbon in it? Coco or sphagnum or anything like that. Also some perlite or anything similar to bring in some air really helps. And 3:1 is a great ratio.Yeah! Another expert on this journal
Started to read the Gee spot thread today, after Azi had pointed me there. Amazing bit of knowledge you fire out
I will look out for those shitty bugs hoping to find nothing.
Those Kosher Choco Kushs are both planted in organic soil….wouldn‘t really call it living soil knowing just that lil about it that I read/learned from you guys on this forum. I know it works on microbes and you shouldn‘t use synthetic fertilizer cause that would kill the microbes/soil. But there might be extra stuff in there that was lab made.
The soil in which Grapefruit Superstar is planted is more like I would define a living soil in my noobie mind. It is made of compost, worm castings, different plant matters and such.
However what do you think? Might I be running into something? I gave them all a lil mag with every watering knowing my tap water is low on mag (20mg/l). Cal is around 100g/m3 which should be 100mg/l. Thought it is good to hold a 3:1 cal:mag.
Both soils got sphagnum worked in. I also added perlite to both of them, remembering that Azi or/and ReservoirDog recommened perlite being around 20% over at the SIP Club. Did it per eye though.Compost is living soil, it's loaded with microbes. It sounds like a good mix. Do you have any carbon in it? Coco or sphagnum or anything like that. Also some perlite or anything similar to bring in some air really helps. And 3:1 is a great ratio.
The tough part with Sips and living soil seems to be finding a balance on moisture content. It likes to get too wet.
Azi is working on that so I would let him do the hard part and wait until he gets it figured
Water and oxygen share the same space in living soil, and if nutrients can't be attached to an oxygen molecule the plant can't recognize the nutrient as food, so if soil is too wet, oxygen is low, and starvation is a foregone conclusion.
This a „Rookie Tale“ after all…..
Did a fixing with duck tape, but 24hours later the upper part started to wilt…it was 
That's why I like to supercrop the stems first.Broke one of the two main stems while I tried to bend it.
Hey Beyond, yellowish tops can be a normal sign of fast growth. If the are a good green all over and just the tips are yellowish it's not likely hunger I think, just normal fast growth. They green up in a few days after unfurling?
Thank you for your reply. They do green up kinda. Just much slower like they did. And if you look at the picture you might see the bigger fans right under the tops having a lighter green where all the fingers connect.
Usually if they wilt they will recover in about 3 days. Not always, but take it from a guy who splits stems a lot, usually they do.Buenas noches amigas y amigos!
Sry for the delay, but…you know life can be challenging…and then you have to take a deep long breath and pause. And admit that you did wrong
Looks good, right? Nope. Find the mistake. Or just let me help, so you all have a good laugh
Yep. Did it. Broke one of the two main stems while I tried to bend it.
Doesn‘t matter now. What’s gone is gone. Trying now to pull some tops from the lower branches up through leaf tucking to fill the spot.
Otherwise, thank you @Gee64 for pointing out the problem of the soil perhaps being too wet. Grapefruit Superstar wasn‘t given any drink since Tuesday morning when I had emptied the reservoir, both Kosher Choco since Tuesday evening. And I believe we can see an increased growth on all plants in the last two days.
However, when I entered the „grow room“ today after work, I could „smell“ them. I know from my previous grow that I watered by @Emilya Green water tutorial that this is a certain sign that they are running dry. I will give them all a drink tomorrow when lights went on….Grapefruit Superstar straight ph‘d tap water in the reservoir…the others get their drinks w/ some nutes. They seem hungry, if I interpret the yellowish tops right. What you guys think?
(@Azimuth do you know why this happened? Ever noticed something like this?) It is the Kosher Choco Kush 2, the tallest.
Oh ok. So another lesson about patients. Grrr
