Would truly appreciate any help

New grower here, looking for a little assistance…

I’m about a month into my grow from seed (3 plants) and I’ve noticed grown rust yellow spots on mid fan leaves. The leaves eventually brown and die ( turn crispy and break apart). I did my research and though cal/mag deficiency so I purchased cali-magi and added 1tsp per gallon but the problem has persisted. I did a full flush and still the same… getting worse. My lights are 25 inches from the leaves and are not hot. PH was 5.9 now keeping around 6-6.1. Also all growth has slowed dramatically… Can anyone diagnose this issue and recommend a cure? Thank you very much in advance for any and all assistance.

I wouldn’t worry about it so long as it is limited to the lower leaves. They will naturally die and fall off. If the rest of the plant is healthy there is nothing to worry about.

Thank you very much for sharing your wisdom. So you don’t think I have any major problem and should just leave it be? Should I cut off those crinkled crispy leaves that are turning brown or leavem?

Yes. They will eventually die and fall off anyway.

Wondering if I should be concerned some leaves have grown these rust spots much more dramatically.

This normal or am I in trouble ?

Also of the three different strains is it normal for their sizes to be dramatically different… crit purple is short and fat, GGlue is tall and lean as 47 in the middle…?

Just a new grower here tryin to learn, thank you to anyone for any assistance.
