Mephisto Grow

Devildog1911 Finally have my space 90% set up. Growing in a 4x4 out in my shed. Temps outside are very cold, but tent is staying between mid 60's at night and mid 70's during the day. Humidity is around 45 percent. I know I can probably bump that up a bit, but this will do for now I guess. Just need to get my air extraction system in place. I have a huge inline fan that is too much fan for my tent. Will be setting this up on a timer so it doesn't run constantly.

Devildog1911 End of week 3 picture. Finally got an oscillating fan (20w secret Jardin monkey fan). Girls are looking pretty good I think, growth is starting to take off. Will be introducing nutrients next watering as I figure the amendments in my coco are depled now. I finally believe I have my extractor fan somewhat optimal. I have a timer set as well as a speed controller. It's on for 1 hour every other hour, and is set at about 25%. This allows my 745 cfm fan to go down to about 190 cfm.

Devildog1911 Things are going well outside of some bad leaf curl.

Devildog1911 Girls are looking good, tent is filling up. One thing I'm starting to notice is some yellowing and spotting on the older growth on about 2 of my plants. I'm hoping it's not a pH issue, but to find out I will be testing my runoff to see where it's at. What should my runoff be? Around the same as what this medium is buffered to? That would be 6.3 to 6.8. I feed every watering (about every 3 to 4 days) and pH my feed to 6.5. I probably need to calibrate my pH meter to be safe though. I also thought maybe it's a N def as well as Calcium def. I upped my feed stregth a little last feeding, will keep it at the same level for this next feeding. My plants always seem to do so well in veg, and then start having issues in flower. Maybe this is normal? I'm still a novice grower, and each time my plants get better. Maybe there's just a learning curve in this game.

Devildog1911 Fixed my pH meter issues, hoping they start reacting to the correct pH feed.

Devildog1911 Looks like things are coming to a close here. Going to give the 2 Sour Stomper another week, then probably 2 more weeks on the NCH x SB.
