Getting worse... Yellow and looks brittle maybe?

For my first, I felt like this grow could not have gone any better... Up until week 7 of flower. Someone said I had a deficiency and to stop the CalMag cause I may have caused some lockout and to only give bloom. Did that. Tomorrow starts week 8 of flower. Am I about to lose all my hard work (ok, it's not that hard..)?

I can't figure it out.

Thanks!!

I didn't water too heavy tonight just in case I need to do again tomorrow if I'm lacking something. I just used Ph tap water on my soil grow tonight cause they was thirsty.

Hard to say, maybe excess Ca caused a lockout - did you try flushing the plant with ph'd water?

Wait a minute... these are just at the top. Could thisa be light burn??? FML I can raise the lights a bit more and maybe turn the intensity down a bit? I'm on the final stretch of this race. What are the consequences of my screw up?

Starting week 8 ? Suppose to finish at what week ?

Technically speaking, yes, but waiting for everything to turn amber etc. Hopefully into the final week

I'm thinking I'll move the lights up if they can go any further and if not then turn them down just a tish. I really didn't want to give them any more nutes this week so they could be flushed prior to harvest. Ima be so mad at myself if this is as simple as lights being too close if I harmed the harvest quality.

In the large pic, you can see the position of those two worst off buds are right next to the wall of the tent, and directly below the bars. Sometimes if you have a lot of air blowing around, I find it can damage tops, especially next to a wall just because of the way the air splits there. You have a lot of large colas, you need to be extra vigilant of botrytis on any bud that get's this kind of damage-it typically infiltrated the bud through a wound. Not saying light/wind caused this, but in this case it might have played a role. Not sure what EC you're running but if it's high, scale it down at this point to 1 ec or so, and id also increase my runoff when I feed.

Thanks! I do have quite a bit of wind blowing around in there and my lights are very possibly too close from their last stretch. I am VERY vigilant in the humidity (running in the 40's right now). I cleared out a lot of things under the canopy so that air could flow between and through everything and place a dual large oscillating fan down below that has one section that blows straight out and another that you can tilt up and down so I made that part blow lightly up from under the canopy. My top fans don't oscillate so I "try" and have them bounce off the walls so as not to hit anyone directly. That said, it is affecting the ones nearest those 2 fans and not the one that's in the front of the tent furthest away from them. I'm trying to read up on this EC thing this morning as that's a fairly new term for me.. Thanks!!

More then likely the plant is finishing up pulling the sugar from leafs … you ever see a tree show it’s “ fall colors “ with diffent color leafs ? Fans , moving lights , click heel 3x not gonna stop a plant from finishing …..congrats you pretty much there ..

Looks like maybe some nute issues at some point. honestly I bet you just had less air movement back there by the looks of your fans and the rest of your buds. I bet they just got hot and crisped up some in the back because it seems to be isolated to that rear area but hey it’s just a thought.
