Just to clarify, the leaf issues will go away with proper res height. I don't believe the cal-mag helped OR hurt the plant, it just isn't needed!

I don't believe you have to. I forget the exact wording they use but their nutrients are ph buffered.
Yes, especially if you are using well water !

PINEAPPLE EXPRESS (PENNY) UPDATE
October 17 to November 6, 2024
October 17 to November 6, 2024
Today's update is on Penny, my second Pineapple Express. She has the same leaf issues that Peggy has. Grow Weed Easy's problem chart shows me that it could be a potassium deficiency. What do you think?
Here are my leaves:
And, here's what GWE has for a potassium deficiency:
GWE says that a potassium deficiency also looks like light burn or ph issues. Currently, the lights are about 18 inches from the tops of the plants and Photone says the ppfd is around 650 for them, which meets the qualifications, I think.
My target ph is 5.8 because that's what bluter does but sometimes, it's either 5.7 or 5.9, which I count as close enough.
Now, let's update you on Penny. Here is her current info and pictures:
Penny - Day 33:
Penny - Day 38:
Penny - Day 47:
Penny - Day 50:
That's everything from me today. Looking forward to people's thoughts on the whole Cal-Mag issue as well as what's causing the brown spots on my leaves,

In all my time growing I have never used Cal/Mag. I've hauled city water, store bought water and for years now just my well water !
AND for the last couple (?) of years I have Not used ph down !
Advanced Nutrients ph perfect, GH Maxi series and Mega Crop one part all have Cal/Mag incorporated in their ingredients and are all buffered or chelated for ph.
This is a Wedding Cheesecake auto on day 83, grown in a 4 gallon hempy bucket with perlite and fed GH Maxi series.
Well water ppm of ~500, ph ~7.5, dry yield +13oz.
And again, I did Not use Cal/Mag Or ph down.....
Front bottom, white pail painted black, over 5' tall
Close up of buds showing condition of leaves...

One other thing....
What is your air movement situation in your tent ?
I have two 7" fans on the floor opposite each other creating a cyclone effect towards the top. Then I have another 7" exhaust fan set to come on at 80 F.
Good air movement = good transpiration = proper intake of nutrients. Well, that's the short version

Hi HG, I think your leaf issue is still an overwatering issue. Take a look at the images in this article.
