Cheese from Seedsman - Nano Grow

Beginning of week.. Never got a chance to update the end of the week last week.. Blah.. She's doing ok.. Her bottom leaves (the oldest leaves) are still getting that weird spotting in between the veins.. Orange or rusty color. The only thing I can make of it.. Is pH fluctuation.. But that just doesn't make any sense to me.. I've kept the pH at 6.1 - 6.3 and check the runoff EVERYTIME!.. It has not been off at all.. Was thinking my meter was to blame.. But it's reading the same as my Apera PH20 or whatever the model number is.. And I calibrate that thing once a month.. Just stopped using it.. My other plant isn't showing this issue.. So wtf.. What is happening and how do I make it stop?!?! The pH is perfectly fine.. I'm sure I would see an issue in my runoff if it wasn't.. I even upped the calcium.. Which I know isn't the issue because it would be on the newer leaves.. Not the oldest leaves.. And the leaves closest to the light.. That's how I've always seen calcium issues.. I wonder if she's being overloaded with something.. I did sprinkle quite a bit of Mico. (Cant even begin to think of how to spell it lol) maybe it's affecting the way she is taking up some of the nutes 🤷 fuck idk.. Back to GWE website to check some more, I guess... Other than that.. I removed a couple leaves (I wouldn't call that a defoliation lol) just to avoid them covering other branches.. I think this will be the last week of veg.. Just want to get these branches in place.. Then let her begin the stretch and then I can find out what my next moves should be.. But I can't know until she stretches.. No more counting my chickens before they hatch lol.. Anyways.. LST'd.. Leaves fuckin up.. Still growing nicely tho.. Flipping to 12/12 next week.. That's about it... Mid week.. Seeing some yellowing on the newest growth now.. Ugh.. This bitch is finicky as fuck! But I'm still gonna keep trying with her.. She's still growing nicely.. Lately, I have just been giving her pH'd water in the runoff catcher (not really a saucer lol) she drinks up a 1/2 Liter in 12 hours.. Even the top of the medium will be nice and moist.. But it is a little difficult to water from the top with all te new growth RIGHT THERE.. But since I've just been using water lately, I'm going to try bottom feeding with some nutes.. I just need a couple more nodes on the branches before I feel comfortable swingin my 1L bottle around in there lol.. But damn she is growing nicely.. Cant wait to see and smell the flowers a cheese strain can make! Whoops.. Havent been keeping up like I should have... All I've done, is defoliated a little.. See next week..
