Germination went good.
I will be using this universal nutrient solution because, judging from NPK values, it should be alright, at least for vegetative stage.
Hi all,
for no apparent reason, my plant is growing super small.
My TS600 at 30 cm distance should be enough, right?
I germinated in Rockwool and now my plant is being top fed for about 12 hours a day (top-fed DWC or Bubbleponics configuration)
My roots are white and growing.
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!
Plant looks like it is recovering.
Flowering should start in a bit as some pistils have appeared.
I have modified the feeding time schedule to 5 minutes per day as Im using a rockwool set of 4+4+1 in order to make a bigger rockwool soil and protect the roots and otherwise it would be too wet.
Ive set 5minute schedule topfed DWC to avoid keeping the roots too soggy. My soil is made of 8 rockwool attached together to form a bigger cube and 1 rockwool on top where I placed the initial seed, to protect the roots. What you think? Are roots ok or too small?
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.
Plant has completely recovered but roots do not grow more than 2 cm from netpot bottom.
It has now entered stretching phase.
I have changed my fertilizer to chili one that has lower nitrogen because it was starting to have some Nitrogen burn. After 2 days, it has recovered.
Any suggestions are well accepted!
Plant is in full stretching now.
I have continued LSTing so to have 4 main colas.
I have noticed that RH was too low and I have just bought a humidifier.
So far, plant looks nice and healthy:)
