Hey, bro! 👋
I checked out your diary and I have an answer and solution for you!
In weeks 3 and 4, you have a clear nitrogen excess in the tissues - glossy shine in the leaves and a very bright green color!
In week 4, you showed the first sign of phosphorus deficiency - the spot on the leaf is close-up in the photo. You can see the nitrogen excess in your photo GG2 w3d7.
The nitrogen excess caused a phosphorus deficiency! 👆
Solution to the problem:
- change the watering pH to 6.3
- change the feeding schedule for the components listed:
gro - 0.3 ml/l
bloom - 3 ml/l
cal/mag - 1 ml/l
Good luck, buddy! ✊😇
