Salts building in your planter, causes lockout. Ph out of whack also causes lockout. Check both.

Brown spots
What is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

What is causing this Leaf discolouration overnight after a lot of tent work yesterday
Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes

I have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Rusty spots mid-top of plants. A couple on each plant. Thoughts?
(Check diary for more details) Thinking calcium deficiency, also maybe magnesium deficiency on a few low yellowed leaves. Thinking it could be nutrient lockout? Feeding them 6.25 pH always. Gonna try 7.0 once and 6.5 for awhile. Thoughts anyone? Im still fairly new and learning

Bud rot? Mold?
My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow). I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :) 1. Is the "brown stuff" on the top bud "bud-rot"? 2. Are the "more intense white spots" mold?

Cal-mag issue that won't go away
I keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg. I include cal-mag every watering and nutrient feed day. You can see images for reference

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.
