Don't feed your plants anything until cotyledons (those round leaves that first popped out of the seed) turn yellow and even after that be careful. Your soil should have enough food in it for at least first 4-8 week. Those pots look like 0.8l, same as I'm using and I usually don't feed but transplant in bigger ones by the time that soil is depleted. Even in bigger pots I feed once or twice before flowering. And I'm also using
biobizz. Keep in mind that
biobizz is organic and there is only 30% of it readily avaliable to the plant. The rest will be digested by the microherd in your soil and be avaliable in the next days. So don't do feed after feed but give them plain water in between. I'd suggest you feed them compost tea until they show you they want more.
You're also staying those are going out. I'd say you won3t need to feed them at all in those pots. Once they have 3-4 pairs of true leave start introducing them to the daylight. Start with one hour a day and work your way up. This way you'll avoid the initial transplant shock. I'd also suggest you keep your lights on close to the day cycle to avoid further trouble. Although your plants won't be sexually mature by the time you put them out you can still save yourself a lot of trouble and stress.
Once you put them out see that snails and small animals don't have acces to your plants or you'll be left with nothing.
Are you keeping them in pots or in ground once outside?
Good luck and keep it green!
