Yes im using tap water maybe thats cause the problem

İn flowering stage im using banana tea  and cal&mag and a littlebit bat guano it isnt enough ?

İ didnt took a pic and they are all gone ive opened big holes under of my pots and i will water them very carefully  hope this time i can be successfull

İm trying to grow since 2020 and i disnt been successfull yet because they are dying middle of flowering stage but i think this time i found the problem after the clones get big enough i saw roots coming out of the soil and they look like dried  i tried to bury but they kept coming out so i found its root rot . They are yellowing and dying in 3- 4 weeks of flowering 

This is root rot right ?

My soil ph is around 7.2-7.5 right now i will try liquid sulphur and i will comment  the resulsts thank you for help 

yes i did, in my country i cant buy fertilisers that producted for cannabis, so im using worm castings bat guano banana tea and homemade cal&mag fertiliser i think the worm castings are increase the ph ,so sulphur is safe ?
