BF Afghan Coco/Growstones Grow Sponsored By MightyGrow 2017

With much light energy its really gonna going to go through some serious nutrients. Being in flower P, K and calcium are being gobbled up quickly. I know Vex is really adding the calmag to his girls under the perfect sun just to keep them healthy.
 
I have been looking real hard at your girls...its tough looking at pics. And not being able to touch.
I think it's a combination.
Light intensity...
To dry....
Causing a conflict with Cal. And P nutrient.
Leaves exposed to light are effected.
Upper growth damaged.
Hard to tell, but new growth looks OK.
Just taking a stab here....
Tone your lights down....
What's your humidity at?
pH?

Making me think ferci! Thank!

Ill tone the lights down good call or ill raise them a bit higher or both lol.

Its been cold at night and i have a fan in my window to blast the cold air in. Its been dry and ive woken up with a raw bloody nose so i assume humidity is low.

The middle leaves def look fine. Its not easy to check oh but i assume its low because ive added a lot of mgo amd it seems to drop ph and needs lime every few weeks
 
Ok, dry air and COB intensity is causing heat stress....Even when temps are in the 70s.
Early signs can look like Cal def.
Strains react differently to humidity.
I'm thinking to low humidity is the prime culprit?
Thoughts?
 
Its hard to say. Ive never had so many problems with my grow.

The cobs are on from 8am-7pm and the room is coldest in the middle of the night to early morming. Not sure if the night temps are affecting them that badly but the cobs are very close and ill get them up higher. The house is sealed during the day but the tent vents out the window.

Im thinking leaving some water in the tray to add some humidty but its never been an issue before.


Ohhhh i moved my fan to hit the canopy for more movement i was worried about mold. Im going to turn them away when i get home.

I think the low humidity at night is made worse with the fans consistanly blowing on the plants plus cobs too close at lights on.

Thoughts on that? Im going to move fans, raise lights, add bloom, lime and maybe a wet towel.

I run my lights at night, because otherwise, I'd have to run heat at night. As temps in NE are starting to drop into the low 50s, mid 40s at night.
 
They seem ok but not sure. Added 4tbsp of bloom and lime. Turned the fans away raised the lights. Putting my ear next to one of the cobs i felt like i got a sun burn for a second. I think the cobs were too close plus the fan. We will see how it goes. Thanks ferc and pw!

Yea that struck me as strange when i saw it. But other than some discoloration up top the look really healthy.

The top is crispy!! but the buds do look fine and same with the sugar leaves. Thank you!!

Its so crazy to me. Those crispy leaves standing straight up! Its the only thing keeping me from cutting them off, once they are forsure on track id normally cut the affected area. They still seem useful so they stay until they fall. Hopefully they take to what i added in the coco alright.
Im really looking forward to harvest. Some time to go but itll be fast im sure.
