Not too concerned but input welcome

So, these are clones that someone gave me. A gorilla glue and a diamond girl. They've been doing so-so since I put them into flower, but the last week the gorilla glue in particular has gotten very yellow all over the fan leaves, dropping most of them. That seems excessive. I give them Miracle Grow Bloom Booster. I'm not too concerned as they are reaching the end of their lives soon, but still... I've never really had any plants that got this yellow before. I've never grow GG or DG before. Does this look like overfertilization?

To summarize;

They are about 6 weeks into flower. I put them under the microscope and the trichomes are about 50/50 clear/cloud all over. I guess another 2-3 weeks until harvest.
Potted in soil, with some blood meal and Dr Earth plant food (never used before until this batch)
12/12 light cycle
2 VisoSun 2000's LED lights



You can see the others that are very green that are about 2 weeks into flower on the left.

Hello!

I've never used MiracleGro so it's possible that it's overfertilization, but that would usually cause more of a 'burn' as opposed to the chlorosis that you're seeing. To me, it looks like it's just the end of the life of the plant and is nothing to be worried about. Enjoy the fade in colors, keep an eye on the trichs and give them another couple weeks.

Losing fan leaves is a normal part of the flowering process. You may have some deficiencies but as you said, it is late in the game. Never use Miracle Grow as the formula contains the wrong nutrients for Cannabis. What you most likely need is for you to add cal-mag to your water.

I keep meaning to get some cal-mag! I made some once out of egg shells and epsom salts but it stank to high heaven and left the plants smelling like something was rotten down below. I'll look into getting some made by a manufacturer. Thanks
