Hello i started my grow 9 weeks ago, I started them off in solo cups using miricle grow potting soil and MG transplanting feed. Using 3x 65w phillips growlights from walmart and a 18" i think 16w folecent light. I have 2 5 gal buckets with 3 10" plants and 2 5gal buckets with two plants in them. One of the ones with two are 11" and 12" and the other one is 26"(my best baby) and 14". No reflective material just a sheet to consile the light and a fan on each side for a small vent. It runs 50-60% humidity and 80-87f during the day and 44-50% humidity 78-82 during the night. I was on a 18/6 for 7 week and just changed it to 24/0 3 daya ago. I was using distilled water for feeding and half a cup of the transplanting solution every week after 5 weeka. I noticed burns on leafs and to much nut. Nit i belive. And salty residue. I stopped the feed and looking for a cheap feed that would be able to get at home depot. Also i have been using carbinated water for misting (i make sure to get under the leafs) but the plants seem to be recovering just fine. I water every 3 days or so. I dont want to invest much more into my set up most ill do is mylar and feed. Suggestions? Im planning on flowering 12/12 in two weeks. Ill post some pics in a bit. My grow space is 4 feet wide 3 feet long and 5.5 tall
