First of all, thanks for the support lads, really didn’t expect people to actually reply. I’m quite overwhelmed lol.
Furthermore, I probably should have provided a little more info on my setup so my bad but here goes.
I’m growing an India dominant strain in stardawg in 11 litre pots, I have 16 pots in 4x4ft space. About 160 plants in total. Pots are in elevated 4x4 trays running a drain to waste system. Medium is just coco professional plus, bought perlite but didn’t use it… using
canna coco nutrient line for the first time.
Lighting is 600w hps, with dual spectrum bulbs,
Will be changing over to led when I have the money.
Running a sealed room with no ins and outs. Using bottled co2 enrichment, at the moment set on around 8-900ppm
Using humidifiers, dehumidifier and air conditioning to control temps and humidity following the vpd chart for veg growth.
At the moment temp is at 25 degrees c and humidity at 60 percent.
Using blue lab truncheon meter and blue lab ph pen.
Using tap water which comes out at 0.2 ec and 7.3 ph.
I’ll post some pics below of my set up and my water checks for my area too.
So I’ve been running into quite a few problems since i started this crop.
First I ran into what I believe was a calcium deficiency as I wasn’t supplementing
calmag, grow store guy said you won’t need it pal so I took his word for some reason lol. Started getting yellow spots with rusty outer lining and plants started to look yellowish.
Then had a problem with my ac which was my fault tbf but came into a sealed room which was 37 dc…. That happened over night so definitely caused some stress there too.
Then to rectify the calcium I brought my ec to 0.4 with
calmag before adding nutrients to rectify the deficiency but I think I overwatered my plants so they all started to droop heavily.
Whilst they were drooping and not looking good at all, I decided to transplant into the 11 litre pots as some of roots were starting to get rootbound whilst they were in the 1.5 litre pots.
When transplanted I let the plants dry out a little and didn’t water for a couple days, just watered them yesterday and could say they look a little better, sprayed them twice last night whilst lights were off with rhizotonic from canna and they look something like this….. also should mention I was running the lights 24 hours so this probably added to the stress but below are some pics of the setup and water data. Forgive me it’s not too clean of a room but just broke my foot in football 2 days ago.
Lastly, I made my nutes 2 days ago and in about 48 hours my ph in my reservoir has risen from 5.8 to 6.4, one of the reasons why I thought of getting an ro system and using potassium silicate as a ph up then bringing it back down with ph down to get the buffer I need, read a forum about this yesterday. Plus potassium silicate would give my plants silica which also helps too right.
Ah forgot to mention and sorry this is definitely the last thing but just bought a soil ph tester and my coco oh coming at 7.0 ph…. Is this really bad?
