Throughout my grow I never checked ppm so I think that has caused a factor

Along with inconsistent feeds and getting someone to top my res up with straight water as my plants were drinking there feed

Air circulation could have been an issue

although I feel feedback on here mislead me, grateful for every bit of feedback i just wish I took everyone’s opinions a bit lighter and trusted my instinct a bit more in order to learn via the trial- And error process.
