The rock wool stayed pretty dry when i was watering them by hand and they were just in a tray ...and now the cubes that are in the pots with the grow rocks were wet all the time ...could that have caused this i have heard that rock wool in hydroponic applications has a tendency to drown root and never dry out enough....and again this is the exact same nutrient solution they were getting b4 i transferred them to the flood table and put them in the pots..and they were super healthy b4 that...
zoomatl Reviewed by zoomatl on . Ebb and flow problem...why are my plants turning yellow? (merged) Can any one answer this...it seems pretty simple but cant seem to get anything in plant problems to match ...i keep having a problem when i switch from one growth stage to the next ...i had ak47 and burmese kush plants in 4x4x4 rock wool cubes which i watered daily by hand with a basic flora nova grow and hygrozyme nutriernt mix the plants flourished ..i did this for almost 7 weeks and was able to sex out the true males...i then took my remaining females and put those into a 4'x4' ebb and flow Rating: 5
