Hello all I'm new to the forum, hell i'm new to any forum on marijuana cultivation been in the closet for 30 years, A manufacturing marijuana conviction over 20 years ago gives cause for the secrecy but things have changed and I'm fortunate to live in a state where it is medically legal and the powers that be look over most non medicinal use. On to my question, I have been growing in coco for a few years now when I started with coir I was in California, Sacramento to be exact and I had to use cal/mag supplements. I've recently moved back to home state of Oregon. Using exact same nutrients everything H&G all their additives everything they have was using Botanicare cal/mag in cali but here in Oregon I'm not having any issues with any lockup or deficiencies. In cali it would start with magnesium deficiency and work into calcium lockup always showed within 1st week of flowering sometimes in the clones vegging depending on strain. Now in Oregon nothing, heck most of the time I don't even need to PH adjust nutes the water here is from the mountains and PTLD doesn't add fluoride to their water supply so with the H&G nutes work very well here. Could this reaction be the water here? it seems the logical conclusion since cali water was atrocious. I'll post a few pics of veg and flowering plants in their second week. I'm wondering do I wait to see or take precautionary measures?
Yep its the water. Sad answering my own post but here is a tidbit for ya!Upon further research I find both cities to be very similar to where their public drinking water sources come from. In Sacramento we have, American and Sacramento Rivers, which provide 84 percent of their water supply. Groundwater provides the remaining 16 percent. In Portland we have, The Bull Run Watershed a surface water supply located in the Mt. Hood National Forest 26 miles east of Portland.The watershed is Portland's primary drinking water source. There are 27 usable wells capable of pumping water from three aquifers on the south shore of the Columbia River. The well field serves as a backup water supply during turbidity events, emergencies and when the bureau needs additional summer supply. That's where the similarities end. Both the American and the Sacramento rivers are used for recreational uses (eg, camping,boating, fishing, swimming) another point, both the rivers and ground water wells are in the valley where everything comes to rest. Sacramento has to filter their water and they add other chemicals to try to get acceptable USEPA (U.S. Environmental Protection Agency)requirements. The Bull Run Watershed is in the mountains, and monitored, No recreational use at all, The only known contaminants of concern for the Bull Run water supply are naturally occurring microbial contaminants such as Giardia, Cryptosporidium, fecal coliform bacteria, and total coliform bacteria. These organisms are found in virtually all freshwater ecosystems and are present in the Bull Run supply at very low levels. Last time I was up there I couldn't get within a quarter mile of the lake before We were stopped and politely instructed by an armed forest ranger to leave the area. Portland's Bull Run is not filtered and they don't introduce as many chemicals into the water to reach USEPA requirements.The first step in the treatment process for Portland's drinking water is disinfection using chlorine. next, ammonia is added to form chloramines which ensure that disinfection remains adequate throughout the distribution system. Finally, sodium hydroxide is added to increase the pH of the water to reduce corrosion of plumbing systems. This treatment helps control lead and copper levels at customers' taps, should these metals be present in commercial and household plumbing systems. The pH of Portland's drinking water typically ranges between 7.4 and 8.1. I can keep blah blah blahing forever anyone can research the info for your local Water Bureau reports online. Obviously regional differences play a huge role in everything associated within life. For plants and animals, Oh and us 2 legged idiots running around pissing in our own pots. Be a good idea to check your local water source reports could lead to less chemicals and water treatment efforts. I know you RO your water and it's perfect because it's RO'ed well back to regional differences if your local water is atrocious then RO it. If it's coming from a more natural sorce then you might not need the extra nutes,and equipment. The PH out of the tap, is probably why here I don't need to PH anything when I follow instructions from H&G calculator add A wait the time stated then add B I give it time to adjust, test PH I'm at 5.8 add the additives and water. no checking PH after additives never had any issues with this method in PTLD, go to Sacramento and wow what a mess extra work, expenses, and added chemicals. Fortunate to be here. I also found out that since I have every dammed product H&G make. if I start to have a Cal/Mag lockup, use Algen Extract it is full of calcium and magnesium, although I've incorporated into the feeding schedule all the way through veg and flowering now at half the recommended rate. Same plants in tent from first post 3 days later. day 13 into flowering 4 different strains of Dinafem White Widow, Dinafem Diesel, Cali Connection's Black Water feminized I ended up with 2 pheno's for this strain and Reserva Prevada's Purple Wreck. Funny these plants in sacto would produce around 60 to 70 grams each. With exact setup, nutes, minus the PHing and the cal/mag supplement and no ROing and location they will produce easily 100 grams each. There ya go it is location, location, location.
