-the pH is 6.3
-I was using the water from my ac/dehumidifier but switched to ro mixed with tap water
-No additives I have cal mag but haven't been using because I thought the tap water would make up for it
-t5 and MH in veg and hps for bloom
Yea that is a possibility because I believe canna has no phosphorus in there nuts exept in the pk 13/14 and the feed chart says only to use the 4th week in to bloom
I have had this problem for sometime and can not figure out what's going on. The lower fan leaves start losing there color and they are developing brown spots as well. The strain is blue dream I grow in dirt the brand is pro mix hp, I use ro water now with a little tap water and I keep the pH...
most grow stores have ph strips, they def are not as accurate as a digital meter but better then nothing. my tap water is like high 8s to low 9s when I was using the strips I could get the ph to around 6. avoid getting the strips for fish tanks though they are garbage
Sorry I miss read your question, I know he uses molasses his whole cycle with liquid nutes and he grows in soil. his yields are not the biggest(IMO this is because of the lighting and pot size) but the buds are premo,
I have used it outside with good results but a long time grower told me to use raw molasses. He also said when you flush your plants to keep using the molasses.
