Help identify leaf problem!~ Calmag deficiency? Phosphorous toxicity?
pillowzstarted grow question 5 years ago
Need help to identify leaf problem (week7-9). Seems like calcium deficiency from the dots on leaf. May be indirectly from phosphorous toxicity and calmag lockout? Or is it from wrong soil ph? Not sure what I'm doing wrong. 😖 Please share some wisdom. Thanks! 🙌

water ph is 6.5 every watering. I tested the runoff ph was around 6.2
not sure if the soil ph is wrong from the nute deposit?
I noticed this leaf problem started after I switched nutes to flowering. I used Flower Fuel 1-34-32 which might be too much too early?

What is your water pH? Do you add calmag to the water?

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

Strange leaves on seedlingHi everyone,
I started those two a day later than the others, the cotyledons grew normal but the first set of leave is quite strange.
The leaves don't grow opposite, but point on the same side... there are also some yellowish spot on them. I put a photo of the others to compare.

Brown Leaf Spots help!I have a serious problem with two of my girls and I can't figure out whats wrong.
The pics attached show the brown spots that have now spread to a good 60% of the leaves on each plant. I've defoliated as much of it as I can and its now affecting even the sugar leaves. Any ideas?

Do these random spots mean nutrient burn/deficiency, or is this normal?I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?
