There were actually two feeding this week. One with just Clonex/Great White and another (4 days later) with Ful-Power, Superthrive and Great White. 400ppm of Clonex and around 100ppm (water is 59ppm) of the other stuff. 2nd feeding is technically very low on nutrients, but as I fed already that week and the fact that Fulvic Acid and Superthrive are very low in TDS in the first place I'm not worried. Again no yellowing=plenty of nutes. The measurements in the nutrient section include everything I fed this week. Also Ful-Power's recommended dose says 20-30ml per gallon. Just in case that seems excessive
Per Grow Boss's recommendation I added green pad jr's in cups to help with extra co2. They're extras I had left over since I finished growing in the dome early so no extra cost. Will switch to TnB once I have a full canopy. Also I hate seeds, Those first two weeks were so slow.
@Frog_Fisher,Promix is pretty neutral and doesn't really come with any nutrients in it since it's a soilless mix. Fox farm is typically pretty 'hot'. In regards to PPM my water is around 50ppm so 170 is actually pretty low in my experience and I was using a good bit of Co2 with the greed pad jrs.
If you watch his Great Root Race video you'll see the plants with the green pad actually yellow pretty quickly as they're absorbing nutrients at a faster rate than the other plants.
@bobo420, Updated pics yesterday. Last pic should show set of two true leaves. Even the first few pics do actually. Cotyledons are below that. If you mean :they don't have 5 leaves" that's a size thing. Technically there's no difference between how the leaves function/show symptoms once true leaves start appearing. Only the cotyledons function differently.
EDIT: Besides, yellowing is from a lack of nutrients and the plant pulling the nutes from the leaves. It's entirely possible for any leaf to yellow if the plant doesn't get what it needs from cotyledons/media. Whether the leaves are "proper" or not doesn't change how the plant gets nutrients.
@bobo420, That's why I mentioned my not getting yellowing yet. If I was (or had other signs of a deficiency) I'd totally agree that the 270ppm was too low.
EDIT: Also Co2 PPM levels with 2-3 green pads should be pretty good. The videos I've seen show that in a dome (when not venting obviously) PPM levels are around 600-700 per pad. Obviously that would be nothing if I was venting, but it's in a closed dome.
I have grown the raspberry cough from Nirvana they were great. Both plants stayed short and stout big indica leaves. Smelled great when they were done as well.
