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.

Leaves turning yellow with brown patches
I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

As you can see, the first two plants look quite good while the last two leave something to be desired. The leaves on the back left are curling downward and
and yellowish at the tips (in places). What could be the reason? I ordered some epsom salt to try it out (sulphur). I grow in floragard proffesional growmix (grown in lightmix from biobizz) and have so far only “fertilized” with supervit, otherwise only pH-adjusted water. pls hlp

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

Brown spots and yellowing
What do you think this is? Nutrients deficiency or maybe soil ph. Happened overnight and the plants are a little dry but I just gave them water and nutrients. My ph tester has been broken so I’ve sorta been winging it with some ph strips.

Deficiency?
I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔) The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight
