Issues after transplant

[DB86]

New to the game. Little guys are a few weeks old, in COCO/perlite. Running 3ml/g Canna nutes A+B+Rh with 4ml/g sensi calmag xtra, and 1ml/g silica. Under quantum board LEDs. 75-78° 30-45% RH. Just moved from solo cups to 5gal fabric pots and this issue cropped up shortly after!

Was just one that I honestly roughed up during transplant (its media was dryer than the rest and fell apart). But now one of my others is starting to show spots too!

Please help!

Just found this form..

-Problem: yellowing and spotting of lower leaves after transplant.
-Medium/grow method: coco and perlite
-Feed and supplements used:-
canna coco A - 3ml/gallon
B - 3ml/gallon
Rhizotonic- 3ml/gallon
Sensi cal msg Xtra - 4ml/gallon
Growtek Pro-Silicate 1ml/gallon
by hand when dry

-Water source:
Deep well water - no chlorine.
Ph starts around 7.5,
Use general hydroponics ph down to get it to 5.6 before mixing nutes.

-Strain and age
Nirvana's Bubbelicious
-Climate: 76-78° F and 30-45% RH
; running two humidifiers to battle dry winter air. Filling both 2-3x a day, so the RH is swinging around a bit.
- Light used: HLG quantum board LED's 600 Watts 24/0 light cycle hours
36inches distance to tops....
-Additional info: How long have the plants been affected? 1-3 days..
How fast did symptoms appear?... a day after transplanting one. 3 days for the other.

You pH after adding nutrients, in Coco it's more like hydro so yes 5.5 to 5.6 after nutrients are added.

Thanks, the silicate is really the only one that moves the ph with these small amounts. But yeah, it's at 5.6 all said and done.

Any idea what may be causing my mystery dots? Did I just screw up their roots transplanting?

No That's a deficiency.

Any idea which one? Nitrogen? Magnesium possibly?

I'd say cal-mag and nitrogen boost.
