Sunday D78 F57: pulled it out just to look at it, looking good, still swelling a bit and I think maybe another week or so. Monday D79 F58: looked at the trics and some are starting to amber, still more glass like than cloudy, but that's changing Tuesday D80 F59: watered with 500mls of pH'd water Wednesday D81 F60: some sugar leaves are looking to be wilting about 600mL of water (I think I might of had an issue as My PH on Tuesday was low and I kinda rushed testing it, might of dropped below 6.2) Thursday D82 F61: not seeing any difference in leaves doesn't appear to be getting worse. pulled it out to check if it might be bud rot. I did not see any fluffy mold so I'll need to check at harvest, but leaves are taking a darker hue so it might of been P lockout. I don't want to create a larger problem by trying to fix what I'm not sure what the problem is. Friday D83 F62: some leaves have died, but the parts that were green yesterday have remained green. I don't expect it to worsen, just see the damage die off. Okay I think I got it, because I looked at the leaf and it was not moldy, in fact it was green and purple (so top half is bleached). Now I remember that I had a spacer missing, 3" , that I noticed a few days ago, but I have no idea how long it's been off. Soooo light burn is what Im thinking. It should be okay just not the best looking. Saturday: watered 500ML
