Hello this little lady just started to flowring yet. Its an auto. Since several weeks she looks like always upset somehow. The leaves are mostly like its dying, turned down and unhealthy. Also flowers turning to yellow sometimes.
There is another fast flowering genetic in the same tent. Her veg developing and strengh is very good but just a couple of days she also looks like a little bit yellow on the leaves.
The only thing I can complain that air flow in the tent. I cannot give a constant airflow because the outside temperature is too low.
I programmed inhale and exhale fans for to work about 20 minutes in every hours to fit the range. The air doesnt smell out of oxygen for me.



Conditions:

Medium: Soil (previously used several times, Biobizz lightmix)

Temperature: 23-26℃ for 18 hours when lights on, about 18℃ when the lights go off. Humidity generally about %60. I give them 500W led for 18 hours.

I use Canna line liquid fertilisers with PH and EC measurements corrected.

They look a little hungry. Can you explain your feeding schedule more? What all you are using in the Canna line, PPM/EC of solution/run-off, and how often you are watering?

I was watering mostly every day but I started lower the volume of watering and period since a couple of days. I thought it may be because of overwatering or some kind of cold shock and couldnt revocered after several weeks. I exactly following Canna's Terra scheledule for feeding. Flores, rhizotonic,cannayzm and cannaboost is what I used since 5 days . EC measurements for 5 days about 2.0 ms, previously it was lower also.
I cannot check the run-off. I guess you mean the outcome of watering from the medium right? I was aware of that topic but when they little I never mind run-offs cause I dont give that much water that can go out from the pot until they grow enough.

What's your PPFD at the canopy? Maybe getting too much or not enough light, hence the slight leaf-droop? They still look fine though.

Not only that you were “ training ” it too … sometimes autos get a slight drag or worse stunt.

yeah this is happned to me many times, I mean staying stunt. I used many different genetics from various suppliers and never can figure out the what I'm doing wrong. Now I have other autos on their first weeks. Do you have any tip to stiumate new borns for better growing? I also use sometimes seaweed a little bit as an extra to Canna products.

I dont have any measurement device.They were always so expensive for me, do you know any cheap solution. I believe quality of leds are ok, cause I get very good results in the past. The distance is about 90 cm. Thank you

I would be weary of over-watering, especially when using liquid fertilizers. However, I would recommend when you do water, that you water until you get runoff (about 10% of the container volume worth of water). Test that runoff to make sure you maintain an equal or preferably lower EC there. That is how you can avoid over-fertilization and build-ups. If you are concerned about over-watering you can look into meters that can test moister content (cheap ones aren't very accurate). If you don't feel confident in your watering practice, and can't get a meter, then I would recommend letting the top 1/8-1/4 inch of your media start to dry a bit. Obviously, you don't ever want your whole media to dry out, but maintaining full saturation in any media is dangerous (people here will disagree for some reason though).

As for fertilization, I have used Canna many times, without any issues. Let us know your EC in solution and at runoff, please. Because my only other suggestion at the moment would be to very very slightly increase your base fertilizer (Flores) temporarily. Though, this could be a bad solution if you have a high EC already or have a higher EC at runoff.

But, as others stated; during the transition phase it isn't uncommon to have this minor nitrogen deficiency. The act of switching straight from a nitrogen-rich fertilizer for vegetative growth to one for flowering can be enough to cause these things. So, if you are following proper practice and following the schedule Canna provides, then it should adjust not too long after the switch.

Make sure you have the right type of paper for the light diffuser, I think it’s 22# 98 bright. Supposedly this app is almost as good as some of the expensive par meters. Worth the $7 imo even if it’s only used as a reference point.

Dim or raise your light and give it a day. They will be praying next day if thats the solution. Always start with the easy fix first before chasing your tail. I think its just light exhaustion that got em a lil light and laying over. Other then that they look fine. Some autos need less light and nutes.

Is it me or is 18.C (64.F) a little low at lights off?
Roots would be a couple of degrees lower than that
