Hey Dude, Scotty, and the DCG! N.E. Nugz here with more learning curve activity on my second grow … Details: 2 Jack Herer Auto Feminized plants that are just into week 5 of flower in a 2 x 2.5 Gorilla Grow tent using a Closet Case, in 5 gal. fabric pots with Fox Farm Ocean Forest; they have a nice breeze from a small fan when the lights are on (18/6). Been watering about every 3 days with 6.3 pH adjusted tap water (after sitting overnight to gas out the chlorine). For the past 2 weeks I have been feeding them Fox Farm Tiger Bloom 1.5 tsp + 2 tsp Big Bloom + 1 T BSM per gallon, giving each plant about 1/2 gal each (and, of course, 3/4 tsp + Recharge) once a week. I stopped using Optic Foliar Overgrow in week 4 of flower. Temps are 75 day/65 night, RH is 45%. No CO2. Recently, some of the newer upper growth developed brown spots and an overall yellowish cast – sorry that the pic has some LED light interference (I think) that look like jail cell bars – I took the shot with my phone. What you see is not present everywhere, just on some of the newer upper growth leaves and a few lower leaves that have direct light exposure. I am very much a noob, so I’m not sure what’s going on – Calcium deficiency? Too many nutes? Multiple nutrition issues? Nothing at all? I just flushed both of them yesterday with about 10 gallons of water (each plant) with 1/2 strength nutes in pH 6.1-ish water – the first run off was about 5.8 pH @ 1400 ppm (EC x 700); final run off was 6.1 pH @ 840 ppm (EC x 700), which makes me suspect there was some salt buildup (?). I’m hoping that this will help the situation, but I’m puzzled as to what the “situation” was (or is) – what do you guys think? As always, thanks for the help ! T-minus one week before we are no longer a prohibition state here – fuck yeah!  🙂
