Nute Deficiency or New Leaves?!
Thoughts if this yellowing may be nute deficiency? Or are these just new leaves and I am concerned about nothing and I’m babying them since it’s my 1st grow? Both plants are about to be 2 weeks post sprout. Both are in 5 gallon fabric pots with layered soil (FFHF on top of FFOF)

Calmag deficiency or Nutrient lockout caused by Pk excess ?
Flo+44. Probably I didn't remove Pk fast enough (left it for more than 19 days, should have left it for 15). So I reduced the nutes from 1.15 to 0.70 now, hoping to avoid the lockout... Thx !

So I checked runoff on watering today and PPM is between 100-150 on each plant. Should I give more nutes on next watering including calmag? Was thinking of going to 1ml per l now?

Fade or deficiency? Day 62

Epsom salt as fertilizer. Whats your take on this folks?
Epsom salt will not release hydrogen ions in water so my guess is that it will thus not affect PH. Making it a nice controllable source of Mg that would be not negligible right? How effective would that be to treat Mg deficiencies? Anyone has experience with this?

Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?
