I'm not sure of the CFM but air is definitely being pulled through this tiny room. I also have an oscillating fan blowing things around in there as well. I have yellowing and necrotic spots forming on my lower leaves. The growth on the upper part of the plants seems to have slowed over the last week and a half or so as well. The blades of the new leaves are very skinny and some are curled but they are green. It seems they are also kind of droopy.

Sorry, when taking the pics I was concentrating more on the yellowing and necrotic patches rather than the new growth.

I'll let the pictures do the rest of the talking.

Thanks for taking the time to take a look.

Time to feed.

Fox farm ocean forest only has nutes to last for a couple weeks...your plants are eating the oldest leaves to get food. Don't trip bro. This is much better than an overfed plant. Infact...once you feed this plant will go off...up pot into a one gallon with fresh soil..

When are you going to flower? What nutes u gonna use?

Do you have drain holes in cups?
they look dry as well.

Thanks for the very fast input.

I had another plant growing from bagseed that I think I over-watered so I was kind of nervous to do the same to these clones. Looking at things now though and hearing what you're saying I do think I need to water more. There are holes at the bottom of the cup. I've been watering about every three days.

I wasn't going to flower these as I want to try and turn them into mother plants. I would like to try and run a perpetual SOG from the mothers eventually. I'm in this for the long haul

Any opinions on the Flora Nova nutrients? Having a look around here it looks like they are good to go. I'm looking to keep things as simple as possible as this is my first run. That's why I haven't even fed them yet lol.

I keep hearing that the newb mistakes are in the extremes i.e. over this or under that so it's hard to find a middle ground sometimes.

I been there brother..take a look at my thread...I grow in soil, ebb and flow and aero using floranova.

I've used organic bat teas, botanicare, dutch masters, atami, advanced and fox farm and im never looking back. Id love to scribe to your journal and help you do it right...there are a million ways of doing it but I tell ya... I keep mothers in soil for years and I have a good method. Lemme know if you want me to guide you...or learn yourself dude.

^ Thanks for the love dude. Just the kind of think I'm looking for around here.

I will start documenting things properly soon. I also planted 10 more bag seeds which I will be documenting as well. Thanks again!

Are you Absolutely sure you don't have what are called Root Aphids. The damage they cause looks very similar to my leaves when I had them. Look closely at the top of your medium, poke around it a little at the top of the pot and watch very close for tiny little fast moving crawlies. When the infestation gets out of hand they sprout wings and fly to other plants to spread out.

ph below 6.5 cal mag lock out raise ph to 6.8 when feeding nd test run off add some cal mag feed grow nutes at 400 ppm till 2 feet tall then go to 700.

lilmiss, I did not see anything like this. Thanks for your input though. =)

Last night I re-potted them and fed them. I went to pick up the flora nova veg concentrate and when I went to check out the guy kind of hmmmed and hesitated and then asked if I would like this for free instead:


"Uh, Yes please"

So that's what I fed them with according to their feeding chart for week three


I'll keep this thread updated. =)

Coolio!
