Plants have exploded into veg during week 2 and are now between 10-12 cm tall at end of week. Leaves start to stretch out over the rim of my pots and all pants are growing their 4th pair of true leaves.
Over the course of week 2 the Hulkberries also started to develop a very faint but distinct, pleasant weed smell that is perceptible a few moments after you stick your head into the growbox.
I still follow Madame Grow's feeding schedule for autoflowers in light soil mixes. But as plants were mainly showing quite a rich deep green and one even went a bit into signs of too much nitrate, I made slight changes:
Plants were fed every 72h with 0,5 L of water with ph 6,3.
First feeding was 0,5ml / L Growth Accelerator and 0,5ml / L of Caribbean Algae Soil & Air.
Second feeding was plain water adjusted to ph 6,3 only with a little Neem oil added in. (See end of entry on that)
Third feeding I reduced the amount of the two nutes to 0,3ml / L.
The Hulkberries seem to still find enough nutrients in the light soil mix to be happy with being fed lower levels of additional nutes than recommended.
Don't want to risk overdoing the nutrients. Imho it's easier to adress a deficiency than correcting a toxicity.
Maybe I'm too shy with the feeding here, but as it's the first grow ever I want to err on the side of caution.
Light intensity was ramped up the last 2 days of week 2. Light is currently about 40cm above plant tops and running at around 65-70% of the veg channel's power.
I'm yet undecided on training the plants. As they are autoflower I ponder the option of starting some light LST at end of week 3, when all have fully established the 4th pair of leaves.
During week 2 I also noticed one single white fly doing recon in my growbox. Took preventive measures and watered with a neem oil solution once (with 2nd watering) and set up a yellow sticker.
Seems to have done the trick, as I haven't seen any fly again since. Let's hope I stopped the invasion right in its beginning.
I'm thrilled to see how the plants will continue to developed throughout week 3.
Hey! Nice grow! I, too, have problems with overfeeding the Hulks. All-Mix is even too hot for veg phase it seems. This strain doesn't even like moderate feeding obviously.
@BavarianBarbarian, True, I will upload the last week. Obviously I just had bad luck with one seed. It shows all signs of overwatering and nitrogen excess, which both can't possibly be the case. We'll see!
@FoxGrow, Yeah, Hulk Berry seems to be quite sensitive to nitrogen during veg. I paused giving nutes for about a week when I noticed the first signs. But the plants all managed to cope with it and I simply cut the amount of the nitrogen heavy nutes down by half after when I started feeding again. Overall the strain seems to be quite a resilient one that can forgive a lot.
