New Growth Yellowing! Need Help

I'm expericiencing full yellowing of new growth, veins included. In week six. I've came up with that it is a sulfur deficiency. I know it is not the most common deficiency, but I think it is stemming from too much calcium. This is only my second round. Decided to use dolomite lime this round as a source of calcium because I use the Earth Juice line and it is lacking in the calcium. I believe I used around 2 to 3 times the amount of dolomite that I needed. This is about the 2nd week of problems. Didn't add the dolomite till the transplant from a 1 gallon to a 5 gallon right before I flipped. At first I thought it was a N deficiency, wasn't thinking about it being only the new growth. I flushed for 4 waterings, straight water 1st 2 times, water with a half dose of EJ Grow the last 2 times, thinking it was a N problem. Plants improved, looked to be heading in the right direction, so I started feeding again. 1st Feed half dosage of everything. 2nd feed full. That's where I'm at. I feed heavy. I use the entire Earth Juice line as my primary nutes, plus I 1 Tb of Molasses per gallon, 2 tsp of liquid fish emulsion plus kelp 3-3-4 per gallon, 1 Tb of Budswel (liquid form) per gallon as my secondary nutes. The soil mix is 1 bag of FF Ocean forest, 1/4 bag of FF worm castings, good amount of perlite, I think about 4 Tb of dolomite per gallon of soil (don't know exactly how much soil I had in the swimming pool I mix in. I added about 30 oz of dolomite as in almost 2 pints in a measuring cup) is a good estimate.

This is only my second round. I used the full EJ line plus molasses my first round with good results. Added the Liquid fish, Budswel and dolomite lime this round. All things point to the dolomite.

My question is will the dolomite flush out of the growing medium like nutes? I would rather feed if I can, can I just increase the Budswell and EJ Meta K (both good sources of sulfur)? Or should I do a heavy, heavy water only flush or resume a flush regiment with lite nutes? Hope someone can help.

Not sure how old the ocean forest soil is you are using, whether it is a new batch for transplant or what, but it holds nutes pretty well for the first 30 days or so. As for the dolomite lime, a lot of the product I have seen is time released, so it takes time for it to actually get flushed out of the soil. If you think you put too much dolomite, I would wait until the soil is really dry and then flush the crap out of it. Whenever I use dolomite lime, I only use about 1 tbsp per gallon of soil.

Thanks. The OF was fresh. Used fine powdered dolomite, not the granular type. The plants are still growing well. Had a little over 1in growth last night. Didn't look like it had gotten worse.
