Why do leaves turn yellow and die
DonCostrostarted grow question 4y ago
Does this look like underwatering, heat stress, or any kind of defficiency? Also might be rootbound, cause I used not a lot of soil which also makes water evaporate faster.
I water 0,8L/2 days pH=6.3=runoff, If its hot some leaves start to droop in less than 48h after watering.

Bro, I saw your diary and you use Biobizz, me too haha! xD
Your girls are beautiful. Nothing to worry about too much. Great job!!!
I think it's because you're using 3ml/L of Bio-grow in the fourth week of flowering; normally, nitrogen consumption decreases as flowering progresses.
If you measure the ppm of the runoff water, we will probably find high values, and the babies don't like soil with too much mineral load. Sometimes when that happens, a blockage occurs, leading to a deficiency of some nutrient.
I recommend starting to lower the dose of Bio-grow; that will improve the soil's ppm. Measure the ppm of runoff and irrigation water.
I saw burnt leaf tips and partially curled leaf tips.
Good smokes! 💪

I think its because the leaves are so shaded she is naturally defoliating herself putting the stored nutrients to better use. Otherwise it looks like a nitrogen deficiency.
I'm not seeing any stress( usually comes in the form of the serrated edges curling ).

Early nute burn or normal?I apologize if this is a stupid question... I'm brand new
What is your guys opinion on this slight discolouring in the centre of the plant.
I'm not sure if this is a really really early nute burn, or if it's just a lack of Chlorophyll

First time grower, long time user!!This is my first grow I have 2 photos that are on day 24, I like that they aren’t stretching but I’m wondering if they may be a little too short and dense, should I raise my light a little or just keep doing what I’m doing? Also the second plant has song yellow so maybe bad ph?

Fine-Tuning Nitrogen Understanding (Deficiency or Toxicity) -- Suspected deficiency, so how do I adjust Fox Farm nutes? Increase ALL 3 nutes to 3/4 dose?Initial inter-vein yellowing, followed by whole leaf yellowing. Minor leaf stem reddening. Older growth. Normal for flower stage (I believe), but too early for normal and rapid discoloration (week 6). This makes me believe it's a nitrogen deficiency, amplified by SLIGHT overwater

Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white
