This can be caused by a lot of things from fungi, nutrients lock and watering ph.
Try to trouble shoot you plant and observed whats doing.
Start with reducing nut. Just give the plant ph’d water. Check your soil ph and makE sure ur temp and humidity its balance.

Leaves turning yellow with brown patchesI 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.

Brown spot on leave. 6 weeks into flowering. -Temp 27'C day 25'C night- HD 65% day 75% night . Soil PH 6.5-7.00. Water always at 6.5-6.8ph.I just flush it 4 days ago because I think it got calmag lockout since I always give them around 5ml of calmag every watering. I only water when 2inch top soil dry with 1.5L of ph balance water. Not a fungus or anything that grow because It cannot be rub or remove from outside.

Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...

What do you think is causing the spotting, leaf curling, and stunted growth in plant #1? My money is on light burn and/or PH issue. I have a PH control kit I've been using to treat the water, but do you think just treating the water is enough? Using FoxFarm HF soil, no nutes yetWeek 2

Brown points and yellowingYo. I have 4 identical plants.
One suddenly started to yellowing (mainly bottom)
But top has some coloring of brown.
Also, i feel like all 4 girls are slow in flowering.
P. S. I have 5l pots. The rest like temp, humidity and ph is normal. I also use filtered water.
