Calcium Deficiency? Any help appreciated

[Clumpyoyster]

Hi everyone. I’ve been having what looks to be a Calcium def but want to hear your opinions.
Grow:
Day 72 or so since flip
5x5 1000w
4”intake/exhaust with carbon filters
Promix hp. (Soiless)
3 gallon pots watered/fed every 3-4 days
Lights on temp 80-82F Lights off 70-72F
RH 40-45%
use GH maxibloom calimagic flora micro
PH watered always at 6.5 with 20-30% runoff.

Started out on just a couple little indica plants but is on more of the plants now. I used a loupe to check for bugs and haven’t found shit

I'm not experienced enough to tell you what it is, but it doesn't look like classic Calcium deficiency to me.

 

[peterstoke]

yeah that looks like a calcium deficiency man especially on picture 5. (the last one). It looks like you have got another problem going on there as well man but i'm not too sure what

Check this chart out. Might be helpful to narrow down the culprit.

you have a fan blowing on them, if so increase its speed, increase the airflow. it helps in the calcium intake. had to learn this the hard way.

Also, what are you using to test the ph of your water? I have a ph pen that I use, my ph up and down kit came with the solution to test ph. I just tried it one day to see if there was a difference between my pen and the actual solution. Sure nuff, there was, and quite considerable. Ph pens need to be calibrated every now and then, the solution is spot on every time. Needless to say I ditched my pen until I can get more 7.0 ph powder to recalibrate my pen. Little more effort involved using the solution, but you’ll never be off.

Pic 5 is one of the older leaves. Pic 3 and 4 are newer developments

I have both set to test ph and that’s exactly why I bought the soulution kit as well as the pen. But my pen is reading the same as solution

I have three fans in there man

Well if your ph is spot on, there’s no other reason other than a deficiency of some sort. Possibly toxicity too. It’s really hard to say. And to make matters worse, you could start throwing all kinds of things at it to combat whatever you feel it is, and end up doing more harm than good. That’s why it’s crucial to catch these things early and stop it from getting worse. Yea I know that doesn’t help you now, but future reference.

I would not even bother with trying to decipher this far into flower , ride out to harvest.

What happens when you run out of leaves?This is why defoilation is a mistake,you don't leave any sacrificial leaves for the plant to use when you have a problem.They are storage for times of need.

Here’s a pics of a few plants. This is day 70 since flip. Any problems from here I’m not really worried about but still like to know. I’m already taking nute strength down and about to start flushing.

did you neem spray them ?

Funny story to that. I did order neem oil and the minute I got it I unwrapped it in the garage and on the way back into the house I dropped it about 2 feet from the door and it smashed everywhere. I am going to get more I have yet to try it but have read a lot about it

 

[Clumpyoyster]

Can you use neem oil in flower as a foilar spray or just as a soil additive? I sure you can use that both ways in veg right?

 

[Dontjudgeme]

To my knowledge you shouldn’t spray anything in flower to prevent mold. I’ve never had to do so.

dude don't spray them that could cause you bud rot or something if you are 70 days in flower that's 10 weeks most breeders only recommend 8 to 9 weeks flower flush them for a week and harvest.

Flushing isnt a solution for anything
