IMO this is somd kind of Potassium deficiency. Might cause by lack of nutrient or the ph is off, if you're using bottle nutrient then check your ph is the solution & if you have no nutes yet give her some

Idk what went wrong
My Special Kush 1 is on week 5 of flowering. 4 days ago bottom leaves started yellowing, yesterday i watered and checked runoff ppm, which was 5000! So i decided to flush. Kept watering with tap water (PH 6.8 ppm 300) until my runoff water was 600 ppm. What your opinion about it?

Yellowing leafs and dying tips
Hello ! In the last few days I founded that some leaf started to yellowing and burning on the tips . Maybe it's all due to the flowering stage but I'll be more calm with your answers that are always interesting and helpful even if the platform allows only one to be selected.

Yellow leaves and tips going brown
A few days ago I noticed some leaves turning yellow and today I noticed the tips of all the leaves look off. What am I doing wrong? To much/little watering? To many nutrients?

Magnesium or Nutrient Burn or?
Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?

Seedling Light-burn or Toxicity
Hi growers! Is this Light Burn, or nutrient toxicity from nutrient dense soil? 2 Mars Hydro TS600 lights at 27" from seedling. PH 6.3 misting soil - RH is 75-80%. - Temp is 77F No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.

My first time growing and my clone has started to get these brown dots everywhere. Now some of the leaves are dying and it’s getting worse. Online it says it could be mildew or a calcium deficiency.

First time grower. Looking for suggestions.
Should I be worried about the slight yellow on the edges of the leafs? They don't looks very healthy. How often and how much should I water during this stage?

Leaves still yellowing
I've been losing leaves to yellowing for awhile now, adjusted my water, feeding it seaweed, gypsum, fox farms big bloom, epsom salts, occasional blackstrap molasses and it is still occurring, is this normal and I'm just worried too much or is there something I'm not doing right?

Yellowing Leaves, Red Stems, Brown patches.
pH is correct - run off ph, too. These are 2 out of 4 plants who show these signs. I gave less Flowering Nut in fear of giving too much Nitrogen. Cal/Mag is in use. Is it Phosphorus/Potassium def? I just flushed and gave BioFlores in recommended dosage again. Thoughts?
