I’ve been purchasing from ILGM for the past 4+ years but this is my first forum post. When I decided to convert a small closet into a grow room I decided on a 150 watt LED from Area51 (yes, this was more than a few years ago, they’ve been out of business for a little while now). The coverage was great for 2’x3’ floor space and heat generated was/is minimal. Initially I decided to go with a coco coir/hempy bucket set up using the Lucas formula and GH micro/bloom nutrients. Soon after that decision I read about the H3AD formula (modified Lucas for coco) and went in that direction. The results were great but there were some problems, namely the plants grew fast and very lush but at some point appeared to be suffering from nutrient burn/nutrient lockout issues. I made on-the-fly adjustments (without being quite sure what I was doing) and ended up saving things, the final product was great. Here’s a photo from about 4 years ago of ILGM Blueberry;
Notice how some of the lower leaves show damage from nutrient burn/lockout. The dumb mistake I made was applying H3AD’s GH 6ml Micro/9ml Bloom per gallon ratio for his plants under 1000watt HPS for my plants under my 150 watt LED. I’ve since made adjustments and have reduced my nutrient concentration by 47% from my earlier attempts (currently at 3.2ml Micro/4.8ml Bloom per gallon with minor supplementation of CALMAG). Below is a pic taken yesterday of an ILGM OG Kush at 2.5 weeks into flower. Some minor tip burn but nothing terrible, plants are overall more healthy than before (there’s also an ILGM Strawberry Kush growing next to the Kush);
Lesson learned? While it’s a great idea to learn form other grower’s grow journals and the various parameters of their set up, always be aware that if your set up does not largely align with theirs, adjustments will be in order. Cheers.
