Slight burn. You're feeding MORE than the manufacturer recommends and manufacturer recommendations are notoriously over what your plant wants. Dial it back a bit, see where 4mL/L takes you after doing a water only feed or two.

Was ist los ? Magnesium mangel oder Stickstoff..Hilfe
Hey guys, I don't know what's going on. My ladies seem kind of sad. They were repotted 14 days ago and have now received fertilizer twice. Before that, they had pH adjusted water for 10 days. The fertilizer is Canna Terra, and I'm giving 3 ml per liter of water plus CalMag.

I have 2 feeds left before I start the 3 week flush. With the state of the nutrient burn, do you think I should start flush now? Or feed half usual nutes for the last 2 feeds? Her leaves will die anyway during flush so that why I'm not so well worried about the nutrient burn.

Nutrient deficiency which kind and/or light burn?
Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

I'm having problems with the soil pH, which is at 8.2. What can I use to lower it? I did a flush with acidic water; will it stabilize? Will the plant suffer in yield? Thanks for the help!

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

Hungry plant?
I got calmag so that problem is down, but she looks a bit pale or yellow. Is she hungry? Also some burned tips but only on top leaves, maybe lightburn? Raised the light 4 inches.

Burns on the tip of leaves
What are those burns? Are they from underfeeding or overfeeding? I was using around 1300ppm but then I decided to use 1000 and it didnt get better...

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.
