Hello,
this is my first Post and i hope to get some Help! :)

Some Details to the Grow:
- She is growing in: Soil from Gardol, Nutrients and Perlite in it
- 20L Bucket
- x2 75W (=375W) 6500k CFL
- x1 23W (=103W) 6500k CFL
- x1 15W (=75W) 2700k CFL
- x1 60W Normal Bulb [Just added Today Morning, she seems to like it tho] Im guessing 2700k
Temperatur is 20.5C°
Light is On 24Hours sometimes i turn it off for 2-5Hours but that's pretty Random

So she has one burned Leaf because she grew into the Light and another Leaf's Tip turned brown after that she seemed to be doing Good.

Side Note: Im LSTing her and a guess of mine would be that the PH may be the Problem. The Soil has 5.9PH itself, at the beginning i was giving her Water PH adjusted to 6.3-6.5 & then my PH Measure Pen broke for a while, it now Works again.In that time i gave her normal Tap Water which i first let wait for 24-48Hours with a PH around 7.0-7.5. I measured the Run off which was still left and it has a PH of 5.5.

The Soil itself has a PH of: 5.9
At the beginning i gave her PH Adjusted Water: 6.3-6.5
My PH Pen Broke and i gave her Tap Water which i first let Rest for 24-48Hours, PH should be around: 7.0-7.5
The Run off PH: 5.5
Ideal PH: 6.5, which does not seem to be the Case, i had this asked before on Reddit but only got 1 Respons which told me to get some dolomite lime which i did, it will Arrive in 2-4Days.
Anything i can do till it Arrives?

Its best to add the dolomite lime before you plant. I'd say ph is a problem its low for soil. My phone sucks and I cant see pics but from what you describe about leaf tips sounds like nutrient burn. What kind of soil are you using?

I'm not sure. I'm pretty new to this myself. I know its best to add the lime before you grow. Could be the ph causing your problems. Sorry I can't help more than that. I'd say someone with more experience will chime in and help you.

the burnt tips look to be from over fertilization.. if you're not feeding them anything but what they're getting from the soil, there's really not too much you can do about it imo.. they don't look too bad, again, imo.. sometimes the soil can be too hot, too many nutes in it, and as the plants are young, you'll see burnt tips like that, and as the plant grows, and uses some of the nutes in the soil, it should go away on it's own..

as for all of the ph testing of the soil and the run off, i'm a firm believer in keeping it simple.. i've never tested the ph of my soil, and surely never tested the run off ph as all that's going to tell me is the ph of the run off, meaning, it's a pretty worthless number ime..
take a deep breath, they look pretty good to me, other than the slight nute burn i'm seeing in the tips.. give them a bit more time and see if it gets worse or goes away over time..
lastly, i'd dump that normal bulb you got, if it's not a cfl but rather just an incadescent bulb.. it doesn't really do much to promote plant growth..

What Surprised me is that till Day 33 she looked all Healthy and Clean but then the Tips started to Change Color, that made me worry the most.
I added the Bulb because the Temps were going down to 17C° and the Bulb helps to keep it at 20C° atleast, thats why i added that Bulb, the Plants seem to like it aswell so for now i will keep it but later on Replace it with another 15W (=75W) 2700k CFL.
Thanks for the Help.I was just bothered because this is my first Grow so i may over Panic it but hearing that she looks Good made me for sure feel somewhat Happy, haha. Thanks.Getting Help here so much faster and better then on Reddit. Appreciate it!
I will see the Days how she does. :)
How do i add the Lime?
Do i just pour some Amount on top of the Soil?
Do i mix it up a bit and water it?
Any Advice is Welcome!

yes, you can add at on the top of the soil and water it in .. i think it's about one tsp per gallon, but lemme double check that amount before you go ahead add anything.. i'll brb and let you know..
if you're adding the light to bring temps up, that's ok then, it just won't help photosynthesis much is all..

Looks normal to me....maybe a little cal/mag deficient but maybe not as well..seems normal to me...

I recon people are saying add Dolomite lime to the soil is not for the PH buffer but for cal/mag. And yes you should mix it in if u can rather than have pockets of it.

Okay i will probably try to get out some of the Soil, mix it with the Lime in another Container and then get it back into the Pot evenly spread it and Water it, how does that Sound?

Probably better to top dress it like racerboy said above. Taking soil out of pot you risk disturbing the roots.

Yea i thought of that too, i just mean to take like the Top part of the Soil and just a bit, so i can mix it with the Lime better and overall better and more evenly spread it, you know?
