Hello ! Hope you guys alright and you're having a good day!
I have 3.2 x 3.2 grow tent
HLG 550 RSPEC light (I've decreased power to 330W)
Willma hydroponics - 4 x 18l - using clay pebbles + rockwool as grow medium. I put drippers in the corner of the rockwool cube, so they can water cube as well (don't know that is a good idea, but plants doesn't looks like overwatered)
I using canna aqua set. I have 30l water and Canna Aqua A + B, Cannazym, Rhizotonic at the moment - I've dose exactly how canna uk calculator is saying.
I keep PH 5.5 till yesterday, today I increased it for 6.0. Seems PH going up itself everyday for around 0.2 and I have to use PH down to decrease it, which is alright I think as plants feeding.
Yesterday I start running water pumps for 2min every 2h before that was 10min / 1 hour
Temp I running 26-28 C (I would have 24-26 C, but guy from who I bought light recommend me to run a bit more temp)
Humidity - 60-70% (Today I forgot change water in humidifier and was really low for a bit - therefore could be around 35 in picture, but it was only today for 1-1.5 h)
EC - 1.2
And 4 lovely girls: Pinneapple Chunk, Cookies Kush, Morning Glory, Blueberry OG
All controlled by my raspberry pi bot
Today is 14 day and yesterday I spot something wrong happens with Pineapple Chunk leafs - they have a brown spots. I suspect that is a calcium deficiency which was caused by low ph I had before ? Do you think increase it will help ? - if no do you recommend me to add some cal-mag into water reservoir together with nutrients? I also have a feeling that the plants could go up better a bit and maybe they missing something too ? ;-)
What do you guys think? In attached photo there is a whole in the leaf - it is something I made by mistake.
Thank you very much in advance for all advices. Have a great evening!
