Germination
2 years ago
  This is my second grow of Watermelon Auto by Royal Queen Seeds. First I have put the seeds in a glass of water for 24 hours and then move them directly in the soil. This is way it has the highest chance of germination. It took only 3 days for germination.

The second week of vegetative growth has started on Day 08 - 2023-07-04 and so far the plants/seedlings are a little too stretched upwards, but I hope they will grow stronger.

Week 3 of vegetation has started. I will start LST probably in week 4 of vegetation, because I think it is too early for now. I will wait another week.

Week 4 has has begun and I have started the Low Stress Training(LST). Also I have started using nutes, since there were minor deficiencies. I am very careful with the nutes, because this strain is very sensitive to nutes and can be easily burned.

Week 5 has started and it is still in vegetative state. There is clear nutrient deficiencies. I was very light on the nutrients, because I know from experience how easily this strain can be burned. I have increased the nutrients, especially the CalMag, because I think this is Magnesium deficiency. It seems that this soil is very poor, I have never ever had deficiencies like that...EVER.

The first week of flowering has started. I have upped the CalMag, but still there is issues on the lower leaves, but is way better and is only on the lower leaves. I have misjudged the soil that I bought, it is very poor in nutrients, not like the organic that I used before.

Week 7 just started and it is full flower mode. There is still Magnesium deficiencies. This soil that I bought is extremely poor and probably will never use again.

Week 8 has started and it seems that all of the deficiencies are gone. Now the issue is with the heat and humidity. It is the middle of August and it gets too hot and dry in the tent. Growing in the summer is tricky business.

Week 9 has started and it seems that all deficiencies are gone. Now a little nutrient burn is present on the tip of the leaves, as it can be seen on the pictures. I have to use less power on the lights, because the weather is way too hot for the end of August and in the grow tent is hot as hell.

Week 10 has started and it is full flower mode. The buds are getting nice and fat. Just using the bare minimum of nutes like 4 times less on what is on the chart and they still got a little burned...

Week 11 has started and everything is going great with just little issues like a little nutrient burn. The buds and colas are getting bigger and fatter by the day and I cannot wait till harvest. No nutrients till harvest, so they can be flushed.

Week 12 has started and it will probably be the final week. No nutrients have been used in the last 2 weeks and can be seen on the leaves, so flushing is going good. Maybe should have started flushing a week later, but it is too late for that.

This is my second grow of this strain and I cannot say enough good things about it. It is very easy to grow and extremely resistant to both cold and heat. I have waited a couple of months to cure so I can test it properly. The high is very strong and heavy, you will get locked on whatever you are sitting...I harvested exactly 49 grams of buds, but I have trim of 4 grams. The buds are absolutely Massive.
