As the first 3 CBD Mexican auto-flower plants had not done well before putting them outside, I decided I had better try to do a better job of getting them started. That was not the first time to grow an auto-flower variety. Last year I had better plants but lots of issue with mold. I decided to try 2 different strains this year. I had 3 seeds left, one did not germinate. This time I am using larger pots. Using the same soil, Miracle Grow that has a little bit of nutrients included. So I have been in the habit of not giving any nutrients until the plans are well established. This time I have added a little bit of Advanced Nutrients' pH Perfect Grow in the water. Not much watering yet, 0 .75 liter just a splash at base of plants. The soil in pots had enough water in it to keep it moist so I did not need much. The LED I am using is equivalent to 600 watts and keeping it about a foot from top of the little plants. They also get some natural sunlight from a nearby window. I have been told that I need a stronger light if I want to finish a plant indoors. So I bought one, still in the box as the manufacture's web site has no suggestions as to light to plant distance.
Yes these 2 plants are doing much better than my first attempt with the Mexican Auto-flowers. They are larger and greener. Some of the top leaves have a little upward curl on the edges. I may have had the grow light a little too close, so I raised it. They got a little real sunshine yesterday. I have a fan on them to strengthen up the stem, but they are still a bit wobbly.
I moved the 2 plants outdoors this week. One is 15 inches tall the other 10. These plants for their age, are the nicest I have ever grown.😀Gave them a good soak before removing from the pots. I had also made the soil wet in which I was placing the plants. We are heading into a very hot and dry week. At least, that is what the weather people have predicted. hope they will be happy planted about 15 inches apart as I did not have another previously prepared plot. I remembered to NOT top the plant. Today is very windy, so I am glad that I had placed old windows around the plants to act as a wind break.
The 2 plants are getting ready to flower. They have a lovely green colour and are still growing. Earlier this week I tied down the top of plant so it would lean over and expose the lower bud sights to the light and stimulate their growth. I included Big Bud and Cal-Meg at beginning of the week, with the notion that the plant might like to have these nutrients already in the soil when they are ready to bloom. I noticed the bud sights getting fluffy yesterday.
Hot dry week, so gave my plants an extra watering without nutrients. I saw these abnormal leaves (pictured) and then I looked up the possible problem the plant was dealing with. My pH has been between 6 and 7, so that may not be the cause. The other possible cause was listed as over watering. ???? During a week without rain. While I have been careful to test pH in my nutrient solutions, the author of one web page suggests that one should test the soil as well. I will purchase a soil test kit.
It rained all week. I mean it rained every day. Yes, some days more than others. With the amount of water the plant has received, I decided not to give more water soluble nutrients. Trying to prevent mold by keeping the plant partly covered to keep a bit of the rain off the leaves. Pretty buds are developing.
Another rainy week finally cleared on Saturday and Sunday to give us 2 days of sunshine out of 7. All the wet weather resulted in only 1 day where I could give the water soluble nutrients. I have 1 plant with purple buds and the other with green buds. The 3 Mexican plants I grew earlier had 2 plants with green buds and 1 with purple. Strange? Seems it is not a stable pheno-type.
Less rain this week so I was able to give nutrients in water three time. The buds are bulking up. Some of the leaves are turning yellow as the two plants mature. I am still curious as to why one plant is green and the other purple.
The larger leaves are turning yellow and I have been picking them off. Only tap water offered this week. A couple of times it was 7 liters of water other days just a couple of liters. The purple plant has out grown the green plant by being almost twice the size.
Just water given this week. The use of the old umbrella over the plants at night has been keeping the plant dry as we have had a lot of dew fall at night. I examined a bud with the little microscope I purchased last year. The trichomes appear to be black. I have only been accustomed to seeing clear, white or light brown trichomes. How do I tell if it is time to harvest?
This was my second grow in this CBD Mexican Auto-flower. The first grow was a disappointment because of plant size and mold. I was able to get plants that were twice the size as the first grow during the first 4 weeks. I did get a wee bit of mold this time as I worked hard to keep the 2 plants as dry as possible. At harvest the purple plant was twice the size as the green plant and produced almost twice the wet bud weight. I am still wondering why some of the plants had purple buds and some green.
I decided to harvest a couple of weeks early because it has rained all week and there is a hurricane storm approaching tomorrow with lots more rain and wind. I have had trouble with mold on a previous grow of CBD Mexican this year. I felt another few days of rain would result in mold.
some work on the soil would be great, like adding Humus (worm poo), like 10kg over the first 20cm of soil, and some cover like chopped leaves. etc. That would increase the amount of roots
