Hey guys , this plant is a month and a week old. The tips are starting to turn soft yellow and very sparse yellow spots . Tony yellow spots. What could this be ? I just transplanted from solo cup to a 3 gallon fabric pot with happy frog and perlite on Tuesday. It is also under a 600w LED light with 2 other plants with 24hrs of light . First plants. Thank you!

LED's cause your plants to have a need for extra magnesium, that's the start of mag def

Can I do a flush at this stage ? I read it could be locked out at roots and not receiving the magnesium and to flush before adding cal-mag

I wouldn't, don't think it's necessary here. Just double the amount of Mg you're giving and watch your leaves closely.

I haven’t started feeding yet since I just transplanted into a medium . I have the soil trio set . Tiger bloom I believe ? Should I start then?

5 weeks on happy frog soil is playing a pay here too I assume, check the bottles for Mg and feed accordingly.
