Looking really good! I would cover the rest of your rockwool with hydroton so that it wont grow algae! What PPM are you at right now?

Today I tested the tent for light leaks. I noticed 2 minor holes and the passive out-take vent (where the extraction fan and carbon filter will adapt) are leaking light. I can close the holes but I cannot close the vent. In the future I can impossibilitate the light coming from the window, but not right now. QUESTION: DO MINOR LIGHT LEAKS INTERFERE WITH THE PHOTOPERIOD DURING VEGETATION?
I understand that it can be a problem during flowering because it disrupts the dark period, but I don't know if this happens during vegetation (18/6 schedule).
The EC on the buckets raised slightly to 0.8 but they are not showing any signs of over-feeding. I must take into consideration that I keep adding pH down daily, and it can partially justify this raise in E.C.
Here are my thoughts on light leak, I don't believe it's that big of a deal as its lead to believe. My reason for this is the fact that for pretty much every night there is light being seen from the moon, and wild cannabis seems to grow just fine the light from the moon. Just my thought, by no means am I an expert on the matter.
lol.... Well I can tell you for a fact that light leaks matter... a lot. Only really in flower though. During veg you can run 24 hour lights on if you wanted to. But you get better growth at 18/6. If its just a few pin holes just put some reflective tape over them. Go inside the tent and turn lights off and double check. Same thing as on outside. I patched my tent holes fast and it was easy.
Whitty, The reflection from the moon doesnt put off any light rays or spectrum lol... Its just a reflection. Same way as you can go into your lights out flowering room with a candle? (I believe is what some use).
@ HunterNitro E.C. is around 0.80 right now. which means 400 ppm total (tap water original ppm is 75)
It makes sense not having issues with light leaks during vegetation. Closing holes is easy, but not when there is an open vent that leaks light, without the exhaustion fan on. I'm going to put the exhaustion fan, although (to keep humidity levels), just to block some light.
I noticed that most kind of tapes don't glue to the mylar walls. Would it be because of the humidity on walls? I guess I'll apply black tape on the outside as an alternative for now.
Changing the light schedule to 18/6 tomorrow, I've let 24h for too long and it must be expensive (the electrical bill hasn't arrived yet). Do you think it is time for them to get the full 400w MH power now?
Cajun, why would it be bad to add more nutes during root growth? Isn't it an independant mechanism? Or is it more like, they focus their energy into leaf growth instead of root development?
