I stumbled accross this thread looking for solutions to my yellowing issue and I noticed the same problems described in the first post up top. This was my first grow and I bought some BBK feminized seeds from here to give it a try. I picked up a couple bags of happy frog soil, Big Bloom, Grow Big, and Tiger Bloom. Also grabbed some Mykos for transplanting, and Fishsh*t for microbes. Running 2 1500W(185W HPS) LEDs in a 4x2x6’ for 2 girls.
Seedlings stage took about 3 weeks to get 4 nodes and I fed it at half strength using the FF chart starting around week 2. Seedlings have plenty of energy to get them up right and needed very little light. Everyone says that FF chart tends to overfeed so I backed it out a little. Water’ed them every few days with a solution of Big Bloom, Grow Big, and Fishsh*t. Used ph’ed water around 6.2-6.5 every time and I never mixed a batch that would sit for more than 2 days. 3 weeks after seedling stage I switched it over to 12/12 and adjusted feeding to follow the chart starting on the column (week 5). I’m now in my 6th week as of Friday and I’m fighting what seems to be a Mag deficiency with similar symptoms in the picture above.
I started noticing brown dots like polk-dots on 1 mid fan leaf about 2 weeks ago and thought it’s genetics. It was occuring on plant #2. These plants are just starting to turn purple now in the 5th/6th week. Then the leaf start to show yellow in the veins and it looked like it matched the Mag defciency. Now the left plant started to do something similar on 1 mature branch but without the brownish dots. Mid fan leafs starting yellow. I tried feeding them cal-mag about 5 days ago and the symptoms continue to worsen and spread upward. It hasn’t affected the bud leafs yet and it started out with 1 or 2 leafs on each plant.
I took my first runoff sample and it was around 4.0. I started to research and then it hit me like a ton of bricks. This whole time I’ve ph’ed the water, but not AFTER I added my nutrients…such a rook move. I mixed a batch and tested it and sure enough I’ve been feeding 4.5-5.5 solution this whole time into non-ph’ed happy frog soil. So yesterday I flushed them both with about 4 gallons each of 6.5 ph’ed water just in case I had some buildup. This was the first flush ever and I’m on week 12. I figured I’m about 2 weeks out from harvest anyways given the signs on the buds. Watching for those folded back brown hairs in the 70% range. So 30% white pistols, 70% brown is right where I think I want to be 
No experience so i’ll wing it!
Going forward I’m going to pop up my ph’ed water to 7.5 to try and offset the soil assuming that a 4.0 runoff is about a 5 in the root zone. I could add lime too but I’m close to the end. I just want to give it time to eat up whats left internally. Next one I’ll definitly adjust the soil. Just wanted to state what I went through given the similarities of issues although mine appeared late in the flowering stage. Any advice is welcomed.
Images from last Saturday. The bathtub one is from yesterday and I didn’t get plant #2 which started this mess with the red/brown dots.

@Sploit just pluck off the bad fan leaves , so you have no Cal- Mag , Molasses or Epsom Salt will help or milk Sir , yes whole milk , powder milk , unsukfered molasses 15mls to a gallon or 10 mls of Epsom Salt should get you to the end , you’ve done great up to this point , so a few adjustments and you golden. Try only watering from the top and feeding from the drain pan and thank me later , you pretty much got it from all your reading 
and researching if you ask me , just tweet ah bit and you will be entering the B.O.M too soon!

I know I have read that you don’t have to adjust your ph if you’re in soil, is this not correct?
@Dino I don’t think that’s quite correct Sir , but the grow pros should know !

@yoshi Thanks for tips! I do have Botanicare Cal-Mag and I’ll add it to the next gallon. I didn’t know there was that many alternatives but that will help me if I’m in a pinch later on. I’m lucky enough to have a really nice hydro store locally and they have all of this stuff. My humididty is around 58-60% at the moment so I have to wait another day before adding anything. I did spray an ultra-light feeding including some cal-mag from the top right after I flushed so it might help. It does look better today. 1 or 2 leaves are green on left half and yellow + shrivelling on the right half, like they are 2 faced. A couple of those yellow claws in the images did fall off with a touch. I don’t have a drain pan because these are huge 5 gal cloth pots. They make a difference thougt. I can’t wait to check the root structure to see how the Fishsh*t worked out along with the distance between the roots and cloth pot wall. I’m hoping the roots stayed about an inch from the wall due to oxygen availability. I do airate my solution for 10 minutes to put some extra oxygen in it but I think the cloth pot allows for a lot of breathing and really helps prevent fungus and root rot naturally.
@Dino1 I thought I could just grab some good soil and go but as you can see I’m running into nutrient uptake issues which in my case is not fungus, bugs, or anything other than absorption issues. I’m thinking that the soil needs to be ph’ed to ensure that the plants roots can intake all those minerals. At 4.0/5.0 a lot of stuff can’t get in even if it’s available at the roots especially Cal and Mag. My thoughts are that both soil ph and solution ph should be close to the 6.2-6.8 range to ensure good intake. But all of this just adds confidence in the grow and every strain apparently is different. Like anything else in life you have to take a consensus and formulate your own master plan. I can’t wait for my next batch. All the XP I learned from this grow was much needed and I still have a ways to go. Harvesting and curing is my next hurddle and I have a plan already.
Just when I think I got it all figured out, I read somewhere where it was a good idea to bounce your ph between 6 and 7.
@Dino1
That chart is everything the plants needs to grow healthy , you’re job is to make sure the average N.P.K ratios is available to the roots , not so much the soil if it’s organic ? If your soil live a bit , you mainly just trying to feed the micro life to feed the plant is why it’s so tricky especially running late in flower, that’s when things can get more challenging from bad watering and feeding management . Just my .2 worth . I think watering in for your micro life and nutrient feeding from the drain pan is a bit more simple and you don’t get all the salt build up late in bloom to cause budding issues . But as you know , it’s been a big conversion from organic to Coco with Jack’s for its simplicity but I think Organics still can he done with fun . Learn ppm or EC and always keep your ph consistent . When you mix your nutrients , find your ppm first and than ph your mix might be a lot more easier , I’m no expert though just so you know , hopefully this will help you get a better understanding . Buy if you can get you’re N.P.K to average in your soil close to what Cha-Ching N.P.K. is you golden from seed to harvest and just make sure your nutrients ingredients has what the chart says in it and that’s it , you will see a much better crop I think

If you just want good dirt to grow , The Purple Cow or Sehum you might be interested in maybe , great stuff !
As @yoshi just pluck off the effected older fan leaves. I would just water at 6.7. Your buds look good. Dolomitic line will raise and help stabilize your PH. Easily for the salts to build up using FF trio, I used FF Boomerang to flush followed up with FF boomerang. If you’re that close to finishing, PH’d water to finish
Are you can layer your soil as well , put happy Frog on the top layer and maybe ocean forest on the bottom , of Coco on the top and happy Frog on the bottom , it’s all comes down to what you mainly are more comfortable with using

Even after my flush, my ph in happy frog remained at 5.0. Perplexing. But since the flush, I’ve had no spread of the rust.
Also thst strain is gelato, and a lot of people told me it’s the strain going purple.
No one can figure out why it’s turning white

@Byronyo white as bleaching or coloration fading ? It’s they in the lights and they high omitting lights, they can get light bleached or burn 
, but let’s see what color is white ?

@yoshi I found a few leaves like this yesterday. Lower leaves only. Most of the plants have perked up.
Today is a watering day. I’ll pluck them and continue on.
Those can be from the lock out @TommyD , most plants 
under average power lights , takes about 3-7 days to see 
visible changes after having any type of deficiency, so it’s highly important when growing to make absolutely sure you can adjust ph , ppm , or EC and give the plants time at least a week , before you commence to flushing suddenly , flushing is a good thing , but if you using Organics mediums , it can be a two edge sword if you understanding what I trying to explain ?
Me personally , the way I grow now lately , I read the plants , meaning I’m checking lower leaves for mobile issues and looking for any signs of what I may not be feeding 
, to me growing is an art , it has a special kind of peace and interest to it and plants to me are as gentle as women in they sensitivity ways on how they respond to nutrients and Ppm’s and what is it women do on they rag , pms I think ? Lol , it’s been over 20 years since I’ve seen or had to purchase you know what I mean I hope lmao 
!
I believe you doing a great job of monitoring and you got the formula, just make sure you watch them and learn to read them so they always happy 
to see you when you check in , many call it praying , when the fan leaves are just perk out reaching for the light almost in way I think saying yes power me so I can fed and eat is what I think cause they love to grow out , and what they grow out , they will feed and bud , if you have good lighting and your feedings and watering is consistent each week , just make slight adjustments is all you have to master that will work for your way or style or environment is key 
, once you dial it in, I’ll say it right now , you’ll be another one here probably out grow me with a few of my Lil quirks and tweaks and your final product weed would be great fire medicine oh yes indeed , so hurry and and wait and learn to just let them be sometimes and you feed them right is all it really takes and you’ll be harvesting 10-20 lbs every 3-4 weeks ?

@yoshi Thanks for that information. I started to think lockout too. I used the search feature here, read some, so I gave them a flush. The Ph went up some 5.5 I got. Funny thing is my auto’s Ph is at 5.8-5.9 on the runoff. Same soil. Plants are 5 feet away, lol. Very strange. I’m getting the idea that each plant and grow is different.
Well they are praying today. Not observing any new spotting. So I’ll keep watching. Thanks
Welcome to raising plants , I don’t think I’ve had two plants grow the same in many years ?
