Multiple issues at once is making diagnose difficult. In need of veteran experience.

This is my first grow, and I have run into a bit of dilemma as I believe my plants are having multiple issues at once, making it hard for me to judge what it is. I'm not going to post my suspicions yet so not to influence anyone's diagnose.

A brief history: I suspected a calcium/magnesium deficiency, which prompted me to add more Cal-Mag. Which made then ran into a nutrient lockout because of excess Cal-Mag, I was hitting 4200 ppm on some run-offs. Thus, I promptly flushed them about 4 days ago. I now have learned Cal-Mag is not much nessesary when growing on soil, is that true?

Medium: Fox Farm Ocean Forest on Fabric Pots.
Water Source: Tap left to sit bubbling with and air pump and air stone for at least 24 hours. When I can not, I've used a water conditioner.
Strain/age: Strawberry Cheesecake Auto and Larry Lemon OG Auto from Seedsman, Both are 47 Days (Week 7).
Light: Spider Farmer SF4000 at 18in.
PAR: ~ 950.
Temperature: Avg 79.7°f, High 86°f, Low 67°f.
Humidity: Avg 59%, High 77%, Low 42%.
CO2: Homemade (Yeast, Sugar, Air Pumped).
Space: 4x4 Tent.
Feeding:
Base: Sensi Bloom.
Veg: Voodoo Juice, B52, Silica, Cal-Mag.
Flower: Big Bid, Sensizym, Carbo Load, Bud Candy, Cal-Mag.
Other Additives: Molasses, Recharge, Snow Storm Ultra as a light Foliar.

You can see my whole feeding schedule on this document:

And anyone who like the document can make a copy. I cannot claim that I did because I found it online. I use Gantt at work, so this works perfect for me. Also, I've tried my best at keeping track of every PH and PPM, but it's my first grow and I forgot while doing it.

Much thanks already for taking the time to read.

:eek1: I think you're going to need a pro to look through this but, are those ppm numbers for feed correct?

Just from reading, those ppms in the thousands are way, way too high. Did you follow a feed chart? Most vendors suggest ppm numbers for photoperiod plants. What I've learned here is that 80% of that is usually more than enough for autos. I mean 450ppm is considered pretty strong for autos and the soil you are using has a lot of nutrients on its own.

Obviously I defer to the far more knowledgeable but I think plain water would benefit you quite a bit until things settle down.

yea, the soil was “hot”, figured that out later in my research about fox farm’s ocean forest. I believe the flush did a good job on getting rid of any build up. Went down to less than 250 ppm.
 
yes, most find( myself included) OF is too hot....Happy Frog is about a perfect start ( IMO) and does good for the first month or so...( I used the left over OF to recharge my spent HF at 1/3 OF mixed well into spent HF)....What is the source of your tap water, city, well etc. Well water most likely has a high calcium content..( used my well water 50/50 with store bought RO till I got a RO system installed).....Afew of the old hands can probably help you finish this grow out with at least something to smoke from it.....treat it as a learning experience, don't be hard on yourself research as much as you can, simplify as much as you can and the next one will probably be nice.
 
As a side note, get your message count up, Live Stoner chat is a great place to do it......And join in the halloween contests....one is even only posting Trick or Treat...
 
IMO FFOF isnt hot really as far as nutrient density is concerned. Although it seems quality control is lacking as its in high demand and it doesnt "cook" long enough on occasion before its sold. You can usually tell by the smell. To be safe simply dump any bag of ffof into a tote and water it a bit and let it sit for a month and then use it. I dont plant directly into it although some do without issue but I wouldnt recommend it. At least thats what ive found and thats what works for me. Happy Frog is also a good soil as mentioned above.. but poops out bit faster. Either are great to reuse and amend with some additional aeration and other goodies. You should have been good with nothing but water and maybe organic molasses for the first 3 weeks. You threw quite a few things at your seedlings in a short period of time.

You certainly did your homework regarding entire set up. Well done. Looks like classic nutrient burn with some lock out. Please take your thread to the infirmary, where the experts monitor.
I’m not going to hold back. Ocean Forest is garbage! Depending on where you live, far better “bagged” options. If you must use Fox Farms, their Light Warrior is decent starter, mostly because it is mostly peat and less likely to come pre-infested with bugs. Happy Frog is ok. Like tom mentioned, the quality control and cooking time is subpar.
The flush, along with some support from the experts, should get you to the finish line.
Most of all, don’t get discouraged!
 
Sorry if my response came off as rude or blunt guys. Anytime I see Ocean Forest as the medium, I cringe. Wish you great success going forward .
 
Circling back to OP:

What water conditioner are you using and have you checked / calibrated your pH meter recently? Have you checked your soil pH (slurry or pour-thru)?

It doesn't quite look like a Ca deficiency, so much as it does a general micronutrient lockout due to high pH (Mn maybe?).

Your starting tap water pH looks really high, and your final feed pH also looks to be at the high end of the range. Not sure how much of your final pH is due to the AN sensi bloom pH buffers, but you may have better luck starting off with RO/demin/rainwater/etc.

I'm using FFOF, and I usually try to target 6.0 +/- 0.2 for final irrigation / feed pH. The macros are absorbed by the plant faster than the secondaries and micros, which can cause build-up and raise your actual soil pH over time depending on your feed amounts and pot sizes.

Hi! I am by means NO expert...however, using Fox Farm Ocean Forest your little ones shouldnt need anything but RO water the first 3-4 weeks. I had many issues with FFOF, so my second grow I switched to Happy Frog instead and got pretty OK results. I have since switched to pure COCO so I know exactly what my plants are getting...because anything they get I give to them!
Personally for me using soil is like driving with blinders on! HA HA

You sure did you homework hon, WAY TO GO....it takes time, you will be just fine!!
:kiss:
