Black Beauty Eggplant



  • Day 64. The plant still appears to be recovering from the aggressive pruning and the new growth appears healthy to me. I've also continued removing some of the diseased leaves that still remained.

  • That's a crazy haircut. But the new growth looks great (and it did not when I was down looking at it in person). So I think we might have crossed the bridge, but let's keep checking in.


  • Nice haircut! Looking forward to seeing how this beauty does going forward.


  • Images are a bit dark but I was pretty aggressive about pruning any diseased leaves. Hopefully this will do the trick.

  • @JT I'm up for that! I'll prune the affected leaves and remove the humidifier. I did install the new fan about one week ago.


  • We may be seeing two things here. Since the plant definitely responded favorably to the lower light levels (the new leaves look good) the lower light levels had an impact. But it looks like there may be a plant disease specific to eggplants that is happening in there. The disease is called Cercospora leaf spot and some varieties are more prone to it than others. For now, it is not a problem at all to trim off any leaves as they start to appear spotted. I believe you have installed the new venting fans, which will help, and it would be a good idea to remove your humidifier tank to make sure it doesn't come on after you open the door sometimes. We want to keep the humidity down in there. There are chemical ways to treat this disease, but I'd rather try to just out grow it and prune impacted leaves if you are up for that!


  • Day 56. On the plus side, it looks like there may be some blossoms appearing. On the down side, the primary leaves appear to be getting worse. My in-house consultant is advising that I prune off the big leaves that are struggling and allow the plant to focus on the healthy growth. What's your take?

  • Day 54. It appears I still have an intumescence problem even though I've taken the lights down to 50%.

  • That new growth is looking better. I'm excited to see how it grows next week.


  • Day 50. I think it's enjoying the change to 50% light. The moisture on the leaf is leftover from when I changed the fan out.

  • As noted, this plant isn't a beacon of health at present. I think it is intumescence, but we'll need to keep a close eye on what happens after turning the lights down to know for sure.


  • Day 48. Here's a closer look at some of the leaves that may have suffered from too much light. The new growth appears to healthy but still no sign of blossoms. I am now in the "Early Fruiting" stage. I assume that's fine although there doesn't appear to be any fruiting but would appreciate confirmation.

  • @I_like_plants yes! That's pretty much the dream of Bloom. By creating recipes that finitely control all variables we can optimize growth tuned to plant type (tomatoes, eggplant, cannabis, cucumbers or Christmas Trees), by variety (beefsteak or cherry tomato) and even get into micro-tuning -- bringing forward specific genetic traits (like controlling for output vs. flavor on tomatoes, or even type of flavor (sweetness or acidity)). And, standing here, we're pioneers with that tech in our hands, looking to create the first rounds of recipes that will then be shared, grown, rated, edited, improved and grown again, in virtual partnership with the plants we're growing. It's going to be a very fun ride.


  • Biomimicry is tricky with plants, they inherently expect correct temperature, light intensity, humidity, organisms (environmental conditions) normally provided by mother nature. These are season based. There may be a lesson to learn and recipes to create based on the known expectations of plant variety.


  • I lowered the light to 85% and I'll do the water change tomorrow.


  • From an onlne source:

    As mentioned, a plant that gets too much intense light will start to show signs of damage. Spotting these early signs is important, as it will enable you to adjust the positioning of your plant to reduce lighting, and remedy the problem before your plant’s health is significantly affected.

    Signs your plant may be getting too much light;

    Brown leaf edges or tips
    Brown, dry patches on the leaves
    Leaves turn pale or yellow, particularly those most exposed to the light
    Yellowing may be noticeable in the leaf tips first
    Leaf yellowing may not affect the leaf veins initially
    Wilting, particularly of younger foliage


  • @BG1164 That (water change) may help. If you would try to turn down the lights we can see about that too. I've never tried an eggplant before, we'll dial it in!


  • @JT
    PPM target is 1275-1325 (1300) and pH is 5.5.-5.9 (5.7). Last water change was done two weeks ago as I recall. I have a stage change scheduled for tomorrow and was planning to change water again then.


  • We are starting to get some wierdness in there BG1164. The new growth is not healthy, and some of the old growth is getting spotty. What are your PPM and pH targets? How long has it been since a water change? We may want to try a few things. 1) these lights could be too bright for a broad leaf plant. In advanced settings, I'd suggest taking your light intensity down to 85%. 2) let's look at your pH and PPM targets and we'll talk about any other adjustments you might want to make.


  • Day 44. I thought I might be getting some blossoms but it looks like the new growth will be leaves. Day 44 Top.jpg
