Did some defoliation this week. The plants are looking fine.
The LED light that I used during the last weeks has a very bad red spectrum, that's why I decided to build a selfmade quantum board with 12 Samsung Q-Series LED Strips. Those are one of the most powerful led's at the market right now (~200lumen/watt). My plants are going to be happy:D

Thank you for that POTent ! Will definitely give that a try, first I need to check the organics RQS provided me (BIG SHOUTOUT TO JAMES FOR THAT ) But for the run following after that one will for sure include the BioTabs. Thanks again and a blazing Christmas for you my friend
Thanks! Well in my first grow I used the autopots with BioBizz nutrients (at first) and Advanced Nutrients (afterwards), which didn't really work well for me. But now with the BioTabs and tapwater everything is going perfectly, because the whole nutrient mixing, PH measuring, etc, isn't necessary. The only work you have to do is mixing the soil and keeping the reservoir full. You should take a look here if you wanna know more about it: https://www.biotabs.nl/pub/media/wysiwyg/pdfs/consumers-engels-small.pdf
I really like your light. Did you make it after reading up on LEDGARDENER.COM? Those strip builds are the most efficient things you can get on the planet right meow.
@first_time_grower Well I read about it in a german forum (grower.ch) how all these led panel companies are screwing us over with cheap led's and fake specifications. Also all these "Best LED rankings" on google are made by the companies themselves apparently.
So I followed a tutorial ("diy quantum board") I found in that forum (I think it was based on the ledgardener tutorial tho). It's pretty easy actually even if you have 0 mechanical skills like me:D And much cheaper than buying a Sanlight or whatsoever.
Hi @POTent! These marks make me think of 2 potential issues: either it's the first sign of a pH fluctuation in your medium, or the beginning of a pest invasion (spider mites and/or thrips). I don't see your pH measurements in your diary, do you check your solution's pH? If so, what values did you apply for last week and for this week? Otherwise, you need to buy a pH-pen as soon as you can, this will dramatically help you to get the most of your babies and avoid deficiencies/toxicities. Now, make sure it's not pests, check carefully both onto and below the leaves, around the stems, in your medium: nothing's moving, nothing's alive? Have you been working on a pest prevention strategy? Like diffusing essential oils, spraying neem oil mixed with garlic, setting up some sticky traps, giving the canopy a good continuous breeze...? If you're 100% convinced it's not pest-related, then try to feed at the correct pH range (around ~6.2 in soil) and see how it goes after a few days. We'll be here to help you and refine the diagnosis if necessary. Hope this will help, keep us up-to-date and happy growing 👊
I read that PH values are not important when growing organic, but it's around 6.5-7. Also I checked the leaves with a microscope but I couldn't find anything. I'm gonna keep an eye on them. Thanks:)
Bro you can treat against bug as you want : it will still be a genetic issue called variegation ! I give you a link to an explanation of the phenomenon : https://www.maximumyield.com/definition/133/variegation
@KilgoreTrout, Yes they were in my room for the first week (it's 5°C outside and not much sunlight). I moved them under the LED light at the beginning of week 2:)
@POTent,ok well get some light on it. If they stretch like that you’re going to have fragile plants. There’s no way they’re outside in daylight. Behind a window decreases intensity. So get some artificial light on them as soon as possible.
