06-06-2021: Growth is still very fast. Last week I lowered my setup to give them some space but it is still not enough. So tonight I will deflate en top them the hard way. I will cut everything that is within 20cm from the lights. I snapped some stems but they where up already after a few hours :(
08-06-2021:This morning I have refreshed half of the water and added 60ml peroxide (50%). Reason was that I saw some slime between the roots. All clean now as you can see. Seemed like it gave the plants an enormous boost.
09-06-2021: Needed to top them because some lightburn was occurring. So I got the scissors and cut all of them.
@ChronicFinest, Well I have very good experience with the TSL 2000 and that was only about €250,00. So they have to perform very well to not disappoint me (value for the money). My average on Mars is about 1.7 gram/watt
Thinking about using one of these seeds (seedsman winning) as an alternate for next grow in case I don't get 5/5 on my Skunk Hero germination. Following your grow for sure. Best of luck!
