Fast-growers starting to show issues.
Got some issues on these fast growers. I've been treating it as a cal-mag deficiency, however I've been feeding calmag for two weeks and its only getting worse it seems. Any thoughts? PH is 6.0-6.3, PPM 444 feed, RH 47-50%, Temp 77-81f.

One of my plants has brown spots on the leaves (see photos in week 6) 2 old leaves on the bottom of the plant became yellow. Ph-value should be ok, 6-6,5 Maybe the plant needs mor phosphor? Can i add more phosphor with the next sprinkle? Thank you in advance for your help.

What is causing this?
What is causing this? It only seems to be on the older leaves and only on this plant. They’re all being fed the exact same.

Yellow mottled leaves with burnt edges
Help. After months of babysitting my "autoflowering dwarf" it's finally started flowering. In the last week though all the leaves have become mottled and yellow with burnt brown edges. What can I do to save her?

Auto seedling discolouration
This discolouration has appeared on the leaves of one of my two gorilla glue autos, it has been there since the first true leaves which makes me think it could be genetic? I’d like to know if anyone has more information on the cause or if anything needs to be done about it.

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Anyone know what’s wrong with my plant? Has had marble Colour effect on the leaves since it was a seedling and is now wilting. I’m debating if I should remove it if it won’t flower properly. To allow the other plants more room to grow as this is only a 750x750mm tent with 4 autos

Purple spots on leaves?
A few leaves have started showing purple spots, some with pale green/whitish bits as well. Picture above. Any help would be great. I’ve been feeding on the BioBizz schedule every second watering, usually every other/every third day.

Is this Phosphorous deficiency or overfeeding?
It happened from day to night, the watering with Fish-Mix and Bio-Heaven was made days ago. Otherwise, I haven´t feed her any bloom nutes yet. Peace ✌️

How do you harvest in hydro (drip system with a tank) when some are late ?
Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...
