My little champ is coming along pretty well as my trial hydro run. CFL still (and yes, I still plan to use CFL & incandescents during flower this run... If I'm not happy with the results, I will consider the MANY forceful opinions expressed here. *wink*).

BTW - The fan I'm using is a "Register Booster" fan... They are made to respond to temperature (to be places by forced air vents in homes) and turn on and off at your set point by themselves. These are wonderful! The on & off gives a great natural breeze effect, and since I'm using CFL and temp never gets high, the fact that they don't blow constantly is a bonus. They aren't the cheapest small fans - about $35 at Home Depot - but I thought I'd pass it on!


The only trouble I'm having is a small amount of tip burn on the older, lower leaves. Obviously not a heat/scorch issue, since temp is good and it's only lower leaves. Older leaves suggest it is a mobile element problem, but I don't know which.

I pruned off the oldest, lowest, small leaves, as some were showing a bit of chlorosis as well - from the tips back, no pronounciation between the veins.

Had a bit of "praying" earlier this week, but foliar Epsom & H2O solved this immediately. Continued spray for 2 days, morning & evening.

Changed the resevoir the next day as well, and added some H2O2 to prevent the slight algae growth cleaned out of old resevoir.

pH has been consistant and is not a problem.

The next oldest set of leaves show just the tip burn. It is truly just the very tips, less than 1/32", and does not seem to be spreading.

Can anyone suggest what is troubling my older, lower leaves?
