Leaves going Yellow with brown spotting - 2 trees/same water/same strain from seed - any idea?

[markybda]

Indoor setup, switched to 12/12 5 weeks ago yesterday. Both trees came from the same strain seed. They both get the exact same water/nutes/feeding cycle.... any ideas? More calmag needed?

Do the bottom half of your plants appear healthy?

yes, they do... where the leaves are anyways

like i said already, there are 2 trees in there, but only 1 looks like this. I attached a pic showing the tops of both, then a pic showing pot and overall height. last pic was taken sideways

When its only at the top my thoughts are too much nutes and or light.

Thank you! Does it look as if the lights are too close?

My guess is calcium deficiency.

If that is coco they are in its too dry. If it is peat you may want to try a bigger container, its hard to judge size in pic but that is alot of plant for that size container of peat mix.

I'm using Calmag...

So out of the 2 trees, 1 has branches that are randomly dying.... last week there was 1 branch, that had a side branch on it... the end/top branch started looking like these two (It was right next to them)
I cut the branch off... right to where the other ARM came off... 2 days later that arm looked the same, so i cut that also.
As of yesterday i am in week 9 of flower. The leaves looked better yesterday, but definitely worse as time/days progress... why is this happening?
I PH the water to 6.7
I'm only feeding CALMAG and water.
I am probably going to cut the branch off where the deadness stops... (on both of the branches....). Remove the dead leaves, and start the curing process on the cut branches

the zoomed in cam pics are ONLY of the tree with these issues (Showing clear/cloudy/amber)

Any help would be greatly appreciated

Might be the plants are dying due to root issues. Over-watered and then under-watered?

I think it’s lack of food since you’re only giving them cal/mag and water. You should also be running a little lower ph like 6.0-6.3 little outside that shouldn’t hurt but it’s a mix of inert medium so you need to feed them every watering and get 20% runoff to avoid salt buildup.
