did you ever get this figured out? i am currently on my second grow with H&G and my first went like shit. Now on my second grow, i am having lots of deficiencies with different plants. I am currently on week 3 of 12/12. Lots of my plants look like the pictures posted in this thread. I am using their whole line (except algen extract). Aqua flakes A & B, roots excel, mutlizen, drip clean, starting budXL next week. There is maybe 15 out of 42 that look green and healthy, but others are showing signs of phosphorus deficiency (brown points/tips that are not crispy nute burn), some are showing signs of magnesium deficiency (leafs curled up), or calcium deficiency (minor rust spotting that is not bugs). I am keeping all bugs in check using orange guard regularly so we can rule out bugs. my tap water is about 35 ppm / 50 uS. At week 3 of 12/12 i followed the feeding chart and added 8.5mL of A & B per gallon, which i had 60 gallons. Once A&B was mixed up the ec was about 1425 uS (micro siemens). after adding roots excel, multizen,dripclean nute strength was 1525 uS. I have been adding 125 mL of MagiCal over the course of the week (fresh nutes A&B on sunday, add 125mL of magical on tuesday or wednesday and add water). Ph adjusted everyday if it is needed and i have also been adding 50 - 75mL of snow storm ultra per week One plant is having some issues where the lower shoots are just crumpling up/drying out and dieing. other than that all the plants are growing fairly well, generally look OK but it seems like there is something more i should be able to do. I am adjust the ph as needed, the room temp is 65 - 85 degrees, have co2 runing at1700ppm, water temp is between 65 - 70 degrees, hydro setup with grow rox,5 gallon buckets, 10" net pots, top feed sprayer heads and two 30 gallon resevoirs with mixing pumps. no airstone. feeding 6 - 8 minutes every 4 hours during the light cycle.
The thing is i have grown with awesome yields using GH - 3 part,lucas formula, and advanced nutrients sensi grow and connoisseur one grow, sensi bloom another grow. All great yields, almost a gram per watt doing hte exact same as described above.
it seems like everything grows absolutely fantastic when i have plants under 24/7 lighting and vegging them with aqua flaks A&B w/ drip clean under flouros with co2 and nute strength at about 900ppm. it just seems like things go to shitte when i move into my big room / bloom room with the 10" netpots, 5 gallon buckets and HID lights. i have selectable watt ballasts and light spreaders to avoid hot spots! wtf H&G. I see the potential with my shit growing under florescents but why do i have the problems when things get big? didn't have these problems with GH or AN. peace and thanks to all who share their knowledge
