First grow RQS Special Kush #1

So, this week the first problems appeared, being my first time grow ever I panicked a bit, but with some reading and help from the community I think I managed to figure it out. Oct 12 - Everything seemed fine Oct 13 - At the start of the light cycle when I checked in on them, I noticed some brown spots on the leaves of all 3 plants. Only 1 leaf for each plant was affected, it looked like either overwatering or Cal deficiency. I ordered BioBizz CalMag + LeafCoat to try and battle it and had to wait 2 days for delivery. Oct 14 - Plants also started wilting, i panicked even more 😅 Still couldn't quite figure out what the reason was for the problems was. Oct 15 - While waiting for the Calmag and Leaf Coat, I thought about the root zone and lifted the pots to check the bottom and surprise - they were wet. It seemed that the water was going down, but there were drops of water on the bottom of the tray, so the soil was always wet there. I went to the hardware store and picked up coasters for hot pots and pans ( it's basically like a lifted grill 1cm above the ground ) with the idea that the air from the fan will dry out the bottom of the pot and won't cause this to happen again. I added 400ml of water to each plant with CalMag and sprayed them with Leaf Coat. Oct 16 - The plants basically recovered overnight and were as healthy as ever. Not sure if it was the Calmag, the leafcoat or the coasters to try out the bottom of the pots, but my best guess is the coasters that lifted the pots, because the bottom wasn't dry anymore. Also got an TDS meter, and my tap water after aerating and leaving out for a few days was about 250-280 ppm, so cal shouldn't be an issue. I decided it's time to top and LST them, because they had like 6-7 nodes already. I removed the top node only and tied them down to the edge of the pot. Oct 17 - Added 500ml of water to each plant with Calmag and a bit of leaf coat as well, they seemed to be recovering OK from the stress. Overall it was quite the week for me, encountering problems for the first time with the plants, but I am glad that they are OK now, and looking forward to the coming weeks. I decided to keep track of my grow from Mon-Sun, with the update for the previous week begin every Monday, it will help me set a schedule and keep it.
