Man I hope you don't run into the problem that I've been battling since around day 30-35 with my Easy Ryders. I've had other people visiting my thread mentioning similar problems growing their Easy Ryders. Around day 30-35 all of my ERs started to develop symptoms similar to over watering (though not exactly), but they definitely weren't over watered. The lowest, largest fan leaves would start to become a lighter shade of green, then they would start to turn yellow from the tip and outer edges of the leaf and work it's way inward toward the stem. The stems would also often turn purple during the process (not always), and eventually the whole leaf and stem would turn completely yellow and would die or would easily come off of the plant. The problem worked it's way up the plant from the bottom up, taking out the largest, oldest fan leaves, and when those were all gone after a few weeks of this, it started taking out the smaller fan leaves, again from the bottom up.
I haven't nailed anything down for certain, but at this point after spending about 3 weeks combating the problem, things seem to point towards the use of molasses as the culprit. I thought it was my new Brita filter since it started right after I changed it, but I switched to distilled water over 2 weeks ago and the problem has persisted, although it seems to improve about a week after I use molasses each time (and seems to be worst in the first 2-5 days after I use it). I don't have any good explanation for why that would cause the problem, seeing as how so many people use it and apparently don't suffer from the same affliction, but nothing else in my regimen changed between the time when my plants were a thing of beauty, and when the problem started, except for my new Brita filter and the use of molasses.
The plants are looking good btw, anxiously waiting to see the results of your grow! I'm on the precipice of ordering a grow tent for my closet and fully equipping it, and I'm really torn between good old fashioned tried and true technology (HPS/MH) and modern LED technology. To date though the only LEDs I've seen that MIGHT be able to realistically do the job cost $500-$900+ for a 2x2 or 3x3 grow tent setup, and the jury is still out even on most of those LEDs. It's just tough to justify for a hobby grower, especially when you can buy complete 400W HPS systems with both MH and HPS bulbs and a decent ballast for $165 plus shipping. Problem is you then need fans and ducting etc., and the next thing you know you're looking at $350-$400 even with inexpensive deals, plus the added electricity costs over time. Ah well, there's no doubt imo that LED will be the way to go eventually, it's only a matter of time for prices to drop and technology to improve. At least a lot of the manufacturers now are hitting the right peaks and using the right spectrums, unlike most of the junk that was being sold a year or more ago (and much of it still is).
