I wouldn't feed seedlings anything until they're growing their first set of true fan leaves. dose should be very low at that stage. Your res really should be circulating but yes if it's sitting still for a period of time I would stir before taking measurements

I've been using both Maxi series exclusively with only CaMg supplement and have no desire to try anything else.

With longer vegy times a 2 plant grow can definitely fill a 2x4 canopy. It really depends on what you want. Faster veg and more plants slower veg and less plants. I use a 2x4 and have overgrown the tent very rapidly by veging too many plants for too long.

I think they look fine. Don't change anything drastically. Roots could be trying to catch up to top growth. Hydroton takes time to anchor in.

I planted some humboldt seed co. hi-biscus which is a cross of zkittlez. Just started 12/12 but the plants are compact and lush

First picture posted of symptoms of the problem almost look like wind burn. I've fried leaves that didn't really have well established roots from a small fan. The pH readings and ppm readings being all over the place also indicates either defective instrumentation or not calibrated or that...

4 days into 12/12 and lush canopy is filling in

You probably want at least 30 to 40 watts per square foot that has a good even spread. If you can achieve that you should be good. I use 4 cob led's in a 2x4 and run about 35 watts per sqft.

I have no problems with over fert. My ppm is about 450-500 (1.0 EC) in veg. At this concentration my reservoir has a very slow ppm drop even as water level is dropping which seems ideal to me. 100ppm of CaMg and the rest GH MaxiGrow fert in RO water. the only downside I see to running the...

The ppm reading could be entirely sensor error. 30ppm might as well be 0. I was using tap with 350ppm and had all sorts of problems. I just started using RO and usually measure 30ppm on it. You should make sure to consider adding CaMg to the RO water. I've been adding it at 1tsp per gallon to...

With hydroton you're going to want to water more frequently. I run a similar drip recirculating dutch bucket system and water 10 min every hour even when the lights are out and they are lush and thriving.

That's a nice innovation there. I will be saving this idea for when I do dwc

Went ahead and topped off the res and put a screen in today. Still running about 1.0 EC and dropped down to 5.7 pH at the top off. 1.0 tsp of CaMg per gallon about 1 tsp of MaxiGrow per gallon.

Plants are really thriving. been steady at about 1.0 EC and 6.2 pH.

Doesn't look like there is much to train yet since you already topped. I would let the node growth start and then you can spread those tops out. when you switch to flowering they will stretch and training will be very beneficial to keep an even canopy

I just flipped some Hi-Biscus today

I would only grow one plant in the aerogarden if i was using it for the entire life cycle. Put it right in the middle and spread the canopy.

I use the aerogarden to start seedlings. I have no issue starting healthy plants in those. I have never used them for a full harvest. Those seed pods hold water for a long time. you have to make sure the watering schedule gives the sponge time to dry out. at this stage you should be using...

Looking very lush tonight

Cleared up most of my worries about droop or toxicity by using RO the past 2 days. used the botanicare line of calmag plus about 130ppm in the res then another 300 ppm of maxigro. watering 5 minutes on and 1 hour off and plants are perky and lush.
