Dang I really wish you had a ppm meter, I got this problem often from using AN with water with too high PPM. AN recommends 100ppm or less, RO being perfect. I've noticed a huge difference following that. Also you said 2ml big bud per liter? I'd cut back on the BB and check water supply.
This is a quite from something I found on Google....I definitely feel like there's a lockout, not def. And it looks similar to what happened to me often over fertilizing which usually started at my water. Was 300ppm and throwing everything off with the PH perfect buffers....
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green though as can be seen in figure 15.
Notice how in figure 16 and 17 the leaves curl upwards like they're praying? They're praying for Mg! The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Until you can correct nutrient lockout, try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.
If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter.
Mg can get locked-up by too much Ca, Cl or ammonium nitrogen. Don't overdo Mg or you'll lock up other nutrients.
May not be a MG deficiency your dealing with but it was the quickest thing I could find referencing to water source. I'm not 100% sure honestly and am only trying to their ideas around and throw out problems I've had with this same line. Specially when I'm competing i try to push them and get problems lol. How maybe this helps trip
