Whats up? Hope your plant is doing better!

How do you test your ph? Pen, test strips, or liquid? To me it looks a little PH stressed. It could be a deficiency like you mentioned. PH can cause deficiency by causing "lockout" of certain nutrients. Always PH correct your nutrient/water AFTER its all mixed up.

Cheap PH pen...

Also how far away are your lights?

Also...to answer your question.. The clone is the exact age and copy of the mother. If she was 2 months old then so is your clone.

Remember... the first grow is always a learning experience.
