Cream Mandarine XL Auto & Jack 47 Auto

The mix for the coco plants since day 16 has been tapwater with 0.67ml/l Gro, 0.5ml/l Micro and 0.33ml/l Bloom, with Drip Clean. This gives an EC of 1.1 which is then pH'd to around 6.2. On day 23 I noticed the first preflowers. I spotted them across all the plants on the same day. The compost plants were tied down for LST on day 23. The grow has provided another opportunity for me to learn something! I have been trying to get a good wet/dry cycle with the compost. I watered again on day 25, which is 6 days after the previous watering, but I got there a little too late. The plants were starting to wilt already. As a result both the plants in compost have yellowing and spots on a few of the lower down leaves. I picked up the plants the day before and I did notice they were getting lighter, but I still thought there was a bit of moisture in the pots from the weight. I wanted the roots to be reaching out and exploring the pots so I decided I would leave it a little longer. This is my first compost grow in the airpots, and I've now learned how heavy the pots are when filled with compost that needs watering. The compost doesn't seem to get quite as light as coco when it dries out, there was still quite a bit of weight to the pots. The plants perked up quickly when I watered them on day 25 but I kept an eye on them with my infrared thermometer. I could see the leaf temperatures remained high (ie, the same as the air temperatures) for the rest of the day, which showed me that transpiration took time to reboot and come back online fully. I've lost a bit of growth on these plants, but hopefully the impact won't be too big.
