New Setup: Bubbleponics!

This little lady is showing classic signs of overexposure to light. You can tell by the way the edges of the leaves are curling up while the main tip is pointing down—this is a strong indicator that it’s getting a bit too much intensity, which can definitely stunt or slow growth. Your TS600 is a 100W light, and at only 30cm away at full power, it’s likely giving the plant way more light than it needs at this stage. Too much light this early can stress young plants, making them focus more on survival than growth. I’d suggest dimming the light down to about 40% and also raising it to around 60cm from the top of the plant. That should give it a much more comfortable environment, and you’ll likely see it start perking back up within a couple of days. Keep an eye on it, and if the growth takes off again, you’ll know for sure that light stress was the issue!

Hey growmie I just checked your diary growdiaries.com/diaries/260115-grow-journal-by-mr-rocket for Week 2, those roots look totally fine. In DWC, it can take a minute for things to ramp up, but once those roots fully hit the water and get enough dissolved oxygen, growth usually kicks into high gear. Your 5-minute top-feed cycle sounds good for no, just make sure the rockwool doesn’t stay soaked 24/7. A light drip rhythm helps promote early root stretch. Once the roots really drop, you can usually back off the top feed altogether. Make sure your water temp stays around 18–20°C (64–68°F) and your air stones are giving solid bubble coverage — oxygen makes or breaks early DWC. And keep the EC nice and light early on (around 0.4–0.6), especially if roots are just poking out. She’s looking healthy — you're doing it right. With just a little patience, she’ll start exploding with growth. Hope that helps, shout if you need more.

I think your buds look fine. It's hard to assess before it fattens up.. it might still suprprise you. Node spacing looks fine, so it is what the genetics allow and given your environment - light, temp, rh, fertiization etc. bud size is mostly defined by genetics as well as how many mouths the plant must feed per sq ft. If you have a shit ton of colas in a small space, the yield doesn't improve. The buds just get more distributed. This could be good or bad depending on severity. You really don't want massively huge buds. It's an e-peen that is just a higher risk of pathogens/infections. Shoot for a Grams per Square foot (mass per area if not on imperial) to judge how well you did with yield. In ambient co2 with seeds, 50-60g/sq ft is great. Clones of heavy yields can probably shoot for 60-70g/sq ft with ambient co2 conditions. Shoot for 3-4 colas per sq ft and keep it healthy. Good results will happen if genetics allow. increasing PK does not boost yield. this is some nonsense that gets repeated over and over but proper research shows this is not true. As far as pk goes, try to give as much as you can, as with anything else, and when you see toxicity, recognize you've gone over that limit and dial back. If other portions of your fertilizer mix remain the same while doing this, it's the 'max' you can give. The overall formula can impact this due to stimulative and antagonistic relationships between the nutrient molecules... you add more of 1 thing, youmay need more of another... or maybe you need less of one thing to allow another to be more readily available etc etc.. The plant tells you... if it is healthy you are probably providing the building blocks at a suitable rate if it is neither building up to toxic levels nor showing signs of deficiency. Rates of use and provision over time... must balance out.. not "more is better". And all of that has to jive with amount of light provided and your climate... It's a bunch of simple relationships but complicated as a whole. again proper light depends on so many local variables, that no matter what suggestion you get, you must do a little trial and error to maximize it for your garden. The developing length of stem between growth nodes ("internode") is your guide for light intensity. Too lanky? needs more. Too tight? needs less... Start at a good suggestion based on 35-40 DLI target, but then allow the plant to dictate. Not unlike the fertilizer above.. start witha suggestion but adjust based on observation. what "should be" doesn't fucking matter if reality dictates otherwise. Too many things vary between gardens to provide a one-size-fits-all answer more times than not.
