Since at this point pretty much all plants are affected, I think I'll stay on tap-water-only, perhaps with a small dose of the Alg-A-Mic that Granger mentioned.
Regarding overfeeding, in a soil-mix such as mine should I be using let's say half-dose of the BioBuzz range, or I shouldn't be using it at all until the plants don't start showing some deficiencies?
Cheers for bumping in!
Hello Lyfespan! I believe you're right with a possible PH lock-out, as until lately (the last 3-4weeks) I didn't have a PH meter and they were getting watered with PH 7.5 tap water - but was hoping that further feeding them with water balanced @ PH 6.2-6.5 could set things straight..
Regarding too much calmag, should flushing help (I've done it yesterday, every plant got flushed with 4-4l of water balanced at PH 5.8) or is there anything else I can do to quicker bring aid to the ladies?
They are still in 1.5gal pots (the 4gal in the title was regarding the first round of CSS), after this flush I'll plant them into 4gal using new medium. As I mentioned, if anything they were getting slightly underfed, as I'm using the "pot-lifting" method and when not sure, also a moisture-level meter that can stick nearly all the way down to the bottom of these 1.5gal pots.
Not sure I got the part with watering using the same calmag level, as I haven't been adding anything apart from what has been mentioned above in the soil mix + BioBizz Fish Mix (swapped with Bio Grow every other feeding), Bio Roots and Bio Heaven.
Thanks for your two cents, I'll try looking into what can be done regarding the build-up of calmag.
Welcome back G., seems that I'm a lost cause here - second round, second time something is screwing up..
Thats a good point you made with trying to get these straight and (hopefully) gain some useful knowledge out of this disaster.
As for Microblast, I doubt any place in the UK will care to make an international shipment, might give the Czech Republic a try, thanks. In the meantime I'll have to stick the the Alg-A-Mic.
I'll prepare fresh soil for the 4gal transplant and follow your tips, but anyway may I ask why do you recommend to drop the coco? Many people write great things about adding coco to soil, even at a 50:50 ratio, hence my question. After transplanting into fresh soil (no perlite, no hydroton - nothing, strictly dirt only?) for how long should I used water only / water with Alg-A-Mic before reaching for anything form BioBizz &/or Microblast (if I can get it imported)?
Many thanks to @ll once more -, let's see what happens next..
Peace out!

Hello fellaz, long time NO C!
Recently I've started a new tent-grow (3x3x6.5) and after transplanting the plants from 1.5gal to 4gal pots they started showing some signs if sickness. I also have a feeling the growth really slowed down. The transplant took place about 2 weeks ago.
Here goes "the chart"
How long has this problem been going on? - last two weeks
What STRAIN are you growing? - Critical Sensi Star
What was the establishing technique? (seed or clone?) - seed
What is the age of your plants? - 10 weeks
How long have they been in the soil mixture they are in now? - 10 weeks
How Tall are the plants? - about 1ft
What PHASE (seedling, vegetative or flower) - between veg&flo (flipped 3 days ago)
What Technique are you using? (SOG, SCROG etc) - FIM / LST / Supercropping
What size pots are you using? (Include how many subjects to pot) 4gal
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) good quality potting soil with peat, mixed with coco (about 70/30 ratio) and added perite, hydroton, blood meal, fish meal, epsom salts, basalt , biohumus
What brand Nutrient's are you using? BioBizz range
How much of each nutrient are you using with how much water? following the BioBizz feed chart
How often are you feeding? every other watering
If flowering, when did you switch over to using Bloom nutrients? about 1 week ago
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect) veg first, bloom after (they go in all together anyway)
What is the TDS/EC/PPM of your nutrients used? don't know/don't measure
What is the pH of the "RUN-OFF"? don't know/don't measure
How often are you testing pH/ppm/EC/TDS? haven't tested
How often are you watering? about every 5days
What size bulb are you using 400W MH (going to HPS tomorrow)
How old is your bulb? 10 weeks
What is the distance to the canopy? about 1.5ft
What is your RH Factor? (Relative Humidity) between 70-80%
What is the canopy temperature? 70*F lights on
What is the Day/Night Temp? (Include fluctuation range) 70*F on / 60*F off
What is the current Air Flow? (cfm etc.) 5" circular duct fan
Tell us about your ventilation, intake exhaust and when its running and not running ? on with the lights (cool-tube), during time off switches on every hour, passive intake
Is the grow substrate constantly wet or moist? no, I allow to top layer to dry and water then checking soil-moisture with my finger
Is your water HARD or SOFT? medium-soft
What water are you using? tap left to stand for at least 24h
So here is the link to my album, showing whats going on.
I've done some reading and my first thoughts were either cal/mag def or sulfur issues (although I've added epsom salts to the soil mix, perhaps not enough - around 1tsp per gallon of soil). It's really not the same for each and every plant (in a few there's been some leaf twisting, some new growth affected etc.), but mainly the older fan leaves started showing these signs (although as mentioned, it's not a rule). Another thing coming to mind are PH problems - is it a must to get some gear and try checking both the soil and runoff PH?
There's quite some pictures, so anyone popping in please take a look and tell me what you see! Also, are they fine to continue into flowering, or with this happening (it's still to a rather small degree, but visible nevertheless) should I get these back to 12/2 untill I manage to fix things?
Many thanks for you input - stay safe & overgrow the world!

PS One picture of the little red, small creatures are coming from the inside of the lid of my compost bin, which is in the same room. What are these things (quite shiny and "pop" when you press them hard) and are they a hazard to my grow? I've tried to carefully observe the plants/tent and haven't found anything crawling around so far. Earlier there was plenty of fungus gnats in the compost bin and recently there's barely any - is it possible that these red things are some sort of predators, eating the fungus gnats and their larva's - or should I worry about them? In seems they don't leave the perimeter of the compost.
