Started week 5 off with watering the plants. The nutrients from the soil are probably used by now so I'm adding a first small dose of Alga Grow.
-- day 30 --
Its been 10 days since I changed the lights to 12/12. Switched the lights to full capacity with the bloom mode on.
-- day 31 --
I'm already seeing the first signs of flowering today. Noticed first signs of light burn so raised the lights to 55 cm above canopy.
-- day 32 --
Watered the plants with 2 ml/l alga grow + 2 ml/l bloom.

I think I've been too cautious with nutrients. Plants are relatively light green colored.
Not sure if I mentioned this before but I chose to schedule my lights so that they turn on at 22:00 and off at 10:00 in the morning. I did this because the room warms up with lights on and keeps the temperature up at night without any heating on to save energy. Only disadvantage; I can only look at my plants in the morning and late evening ;)
A lot of good information here. You are high with your lighting levels though and too close with your fixture. Aim for about 100 umol. in veg. until they are ready to take some more when you have a full canopy. ie. the leaves are tending to reaching for the light, not drooping. Good luck with your grow. You are off to a nice start.
@Mr_Positivo, "this problem shows you what was happening in your garden back then" this is a very good point, I removed 2 plants from the room couple weeks ago and they too showed signs, so I wondered how that was possible. Here's my answer :)
@GeorgeMaas, No problem. These leaves are weeks old so this problem shows you what was happening in your garden back then. You may have fixed it by now. Monitor closely the new growth along with the condition of the existing leaves showing symptoms. Hold plants up to light, back lighting the leaves will show you tips and stripes in its early stages. Leaf color should be perfectly even.
cheers and good luck, bud.
Hey GM, If your leaves were suffering from too much light they would not be reaching they way they are. They look absolutely beautiful and vigorous so clearly something about what you are doing is on point. Take a closer look at your nute regime or soil make up to find the source of your problem. Check your ppm's. If I was growing in coco, I would be in the 450 range. Hope this helps. Cheers.
@GeorgeMaas, leaves that have been exposed to too much light look a lot like leaves that have been overwatered. Its not always easy to tell from the outside. The leaves droop but also they curl under like a taco and narrow down in their profile and they miniaturize. I don't think you have any of these problems.
Most growers will tell you plants with leaves praying is the state you want your plant to be in. Keep up the good work.
@Mr_Positivo, thanks for the reassurement :) I read that leaves can also turn heavily upwards when there’s too much light (to minimize the light surface) I might just started a bit too late with feeding the plants while in vegging. With the minimal amount of heat I have, it probably also means the plants are watered less because of less evapouration, which also means less nutrients. Next grow I’ll start feeding in an earlier state. I can see a big difference in the amount of buds thats developing between the healthy and less healthy plants (will upload photos tonight) thanks again :)
