Here’s my 2nd grow. 1st worked out Ok, but I upgraded to a 4X4. It’s tough keeping the temp in the zone for some reason. But here we go.
Strain: Nirvana OG Kush
Grow medium: Soil Fox Farm Frog with added perlite
Ph: All water was ph’d to 6.5
Nutes: I haven’t used any yet. Water, some Cal-Mag 2ml, molassas and stump tea
Temps: Been between 80-82 during the day. 78 at night.
Humidity: kept around 45%
Ventilation: 6 inch AC xfinity.
Room: Basement. With Tent
No need for dehumidifier.
Been watering about every 4-5 days when dry. All was well until I found a problem today.
Lighting: Spiderfarmer SF4000. I only made it up to 70%. Now I back it down to 65%
Everything was working well. With the warming weather I’m finding it hard to keep the temp in the tent consistent. I have a temp on the floor it reads about 70 deg. I have one, a sensor, at plant top and it’s up in the 80’s. That’s quite the difference. Something is up?
I was wondering why two plants are light green, while the other is dark green? Is that just something that happens? I’m guessing it is. The LED is only at 70%, moved it to 75% this morning. I’m being careful with that LED, but can’t get it out of my mind that the light is keeping the 2 plants light green. It just doesn’t seem that way to me…
Just wondering. Thanks again. I’ll keep involved on this site.
These look normal still. Just genetics? I gave them a shot of Nitrogen.
Now even the other plant that was totally green is lightening up and lower leaves turning yellow.
I lowered the LED 5% too. @Randy_Marsh@Covertgrower Still looking ok?
Getting closer to the end, and probably will start to lose more fan leaves. Just let her finish, I would run the nitrogen a little higher next round. Too late to change anything now.
It’s not a huge mistake, but this is one of the reasons we run so close to nutrient burn most of the time.
She’ll buff out as dbrn32 always says.
I bumped up the nitrogen. Used fish tank water, cal-mag and small amounts of GH brand micro/grow/bloom. 2ml per gal if that.
This grow has got me, lol. While I’ve been growing for 40 years, this is my 2nd. I’m doing the same as the first, which worked out ok, but the OG Kush is not acting like the Sour Diesel. This seems to be too much now?
I used only water for first month, minus a stump tea and thought I was keeping nutes low, but I still got this at the moment.
I hope these girls are ok. @Randy_Marsh@Covertgrower keeping all up to date. Thanks.
Looks like some phosphorus deficiency. Too late now, but they’ll finish. I would increase the PK if you can.
This will likely get worse, as when it shows on the leaves it’s been heading that way for awhile.
Thanks. OG Kush is apparently difficult to grow. For a 2nd grow I should have used another strain.
I’ll up the PK. I normally do late in a grow.
I’m still a long way from harvest, Jeez, I hope they don’t get worse. This might be a lost plant I guess?
Still have one that is real green, lol
Thanks for the info guys. I’ll keep posting.
