Hey, Nick. How are the plants? Did you ever try foliar feeding with epsom?
Hmm maybe you should use the well water then??
Stop putting Epsom in our res.
Don't use that blue chart. It sucks. St0ney made it after battling issues and threw in Epsom at the behest of OzGrowa who was an SOG dude, and, I have seen better SOG gardens.
But that is my memory. I am on a fuckin' missin with that chart apparently.:ridinghorse:
Use the black and white chart that is floating around.
Don't use PBP. It sucks. I did the PBP with Epsom one run. Had some issues looking like yours. You are hydro. Yes, some people can have okay lcuk with it, but it is not neccesary. Unless you use shit like PBP which is way, way low in Mg.
You need to redesign your nutrient regime and the way you are utilizing your growing area. Are you medical? Have specific plant counts, etc?
I'll reread the thread later on today, but this regime isn't working, fill in some blanks in detail about how long you have been growing, and any other garden issues and maybe some of us can get you rollin' in the right direction with the farming of Sweet Lady Jane.
I also have been adjusting the pH too often in the res. i have been working on this and trying so hard to fix the problem i think i have gone overboard on the calmag and also ph adjusting.
I used to have some drift in the pH in the res because it would rise after i mixed the batch until i adjusted it. Now i have been monitoring this stuff several times a day and adjusting too much. i think this is leading to lock out or poor uptake.
I noticed on the PBP bottle it has Mg and calcium in it. When i use the filtered or RO water, is there ever a situation where you don't use any Calmag with this type of water or is it a must?
Gonna have to disagree with you on that one, REZ. While most strains will do well w/o CalMg issues using the recipe, or other nutrients, most nutrient regiments today can benefit from a extra dash of sulfur. While sea salt is a crude mixture of sodium compounds, epsom salt is pure magnesium sulphate, MgSO4. Plants require a ton of Mg and can't have too much of it, however when too much is present, it locks out Calcium and Potassium. The presence of sulphur is not only used as a micronutrient in the plant, but it assists chemical bonds and allows better uptake of Nitrogen. This is the premise of Lucas, cut out excess Mg and N in bloom to help increase mobility and uptake of calcium and potassium, which are more necessary in bloom. However, sulfur is a necessary micronutrient and most people these days find themselves using additives like Bud Candy or Sweet or FloraNectar, or even just molasses. They feel they need these to augment flavor (this is today's main argument against hydro from the organic guys). This is because of the sulfur content, read the labels on those 'sweetener' additives, on almost all of them the main ingredient is Magnesium Sulphate. Cannabinoids and terpenins are complex sulfur compounds and cannot form correctly without the presence of sulfur in the nutrient schedule. Most of these compounds form late in flower. Anything that we perceive as a strong odor (usually stinky) contains some amount of sulfur. Most complete nutrient lines and soil mixes used by growers today lack the correct amount of sulfur. The reason is that most of these nutrients and soils were formulated 15-20 years ago when there were higher concentrations of sulfuric acid (acid rain) in our atmosphere and ground water. Nutrient and soil companies back then reduced the amount of sulfur in their products to compensate. In today's world, environmental regulations have reduced a lot of the sulfur around us, and most indoor growers today are using filtered water. This resulting lack of sulfur causes a lack of flavor in the finished product. The nutrient companies are aware of this, but instead of adjusting their micronutrient line, they seem to find it more lucrative to sell you "flavor enhancing additives". If you are growing in hydro, the sugar in molasses will do very little to help your plant, the sugar only feeds the microbial life found in soil. The sulfur content however makes a huge difference in taste and smell!
As far as Mg and epsom salt, you definitely need it, check out this post on another site from Green Mopho
