Newb asks for helpful diagnosis

Hey everyone, Im a new member here but have done a fair bit of lurking on the boards. I live in the Caribbean and have had moderate success growing a few plants outdoors in the past. After seeing some of the smaller grow cabs/boxes Ive decided to throw one together using mostly scraps from my work truck (Electrician) using CFL bulbs. My first batch is from some decent bagseed as a bit of an experiment.

I used happy frog organic soil (40%) with promix (30%) and perlite (30%). The plant went into this mix about two weeks into veg. stage. 6 Cfls include 2- 42 watt @2700k and 4 -26 watt @6500k. The only nutes Ive used were a weak solution of fish emulsion with the last watering. I also had 1 drop of superthrive in the solution.

I dont have a Ph meter yet, Though I do have pool test strips that have indicated my waters' (rainwater) Ph is about 7. It should be noted that low for a pools Ph is less than 6.8, but after testing my run-off the strip indicated very low Ph or yellow. I attempted to counter this with a tiny bit of baking soda in some water. I havent had a chance to check the run off again because the plants wont be watered again until tomorrow.

What Ive noticed a few days ago is the lower older leaves turning a copper/gold/rusty color from the inside/middle of the leaf. This is happening on at least 2 of 5 plants. The tops of them still look lovely, though.

These pics are not of the highest quality.
Heres the most affected, discolored leaves are north and south

Welcome to RIU :hump:

Those pics dont look too bad. Maybe a bit of nute burn on the one leaf tip. Here's a link to ID plant problems. It has good pics too :)

Thanks for the kind words Boneman.

I have become intimately acquainted with this IC guide since I noticed the discoloration, but cant say I see anything that is the same as what Ive got. Nute burn is probably the closest, maybe Boron...?

Would I have nute burn from just the organic soil and a little fish emulsion?:dunce:
