Something Iā??ve found with my T5 is that I always get lower leaf discoloration.

I donā??t know why, It might be because the plant grows so fast under that light that I just donā??t feed it enough.

Iā??ll attach some pics. IT happens to all the plants, and stops once I put them under my MH

But check out the Axial growth on these guys, thats what the T5 does best.

it's best if you can get really small clones or seedlings under it, they just become little bushes. Sometimes the side shoots grow as fast as the terminal bud. it's great
