A ph higher than 7 in a semi soilless media will lock out Potassium, copper and iron. Long term lockout combined with those low temperatures will kill the plant. Your soil sounds more hydroponic and less like a compost based soil. I would aim for a runoff ph of 5.6-5.9 with sphagnum/peat mixes
The peat was a gardening bag with 15-5-10 NPK and the 30% reused soil is also "live"soil.
27-23C are not low temps, actually the other plants which are enduring 4 to 16C are doing well (smallish but thriving)
I will start monitoring the PH every watering.
I also used another clone and repotted in organic gardening soil and put it in my terrarium to see if it improves (diff conditions, diff soil... if this clone also wilts them the plant is sick, if it thrives the ph test on the others might shed more light.
I looked at buying the soil test kit but the delivery to EU is overkill and sadly not available in the local stores here... Will see if i can get something similar here.
They are in Veg, the mother just left space in the flower room so they moved there but are still on a 18/6 schedule.they look like over watered also , i would switch back to veg and get them healthy again
Will let them dry a little in anycase now have to deal with the slight gnat infection.
