Troubleshooting Hydroponics Marijuana Problems
At a certain point while you are growing marijuana in a hydroponics setting, you may get the chance to encounter certain problems which may be quite difficult to deal with. Well, the solution is not really to throw the plant away, considering the amount you have invested on it, but to troubleshoot the issue as soon as possible, before it is too late.
Here are some of the most common problems in growing marijuana in a hydroponics setting, as well as the solutions for each one of them:
- Leaves Turn Yellow And Dying
This is a scenario that may happen during the early flowering stage. This condition is oftentimes caused by a root disease. Actually, in this situation, the plant suffers from major deficiencies. In order to identify the problem, check the root of the plants. If you notice that they are brown, then it may be an issue of oxygen starvation.
How to treat: Check to make sure that your water temperature is 25 degrees Celsius below. Aerate your nutrient solutions. Add ½ strength of the nutrient to what you typically use during this period. Add systemic fungicide and use the solution for a week before dumping the tank again. For the second time, remove the fungicide, and wait for another week. On the third time, add preventives for root disease and use according to instructions.
- Tiny, white spots found on the leaf
There are two possible causes for this scenario. First, it may be a mildew/fungal problem which can be solved with a fungicide spray. The second is the possibility of an aphid problem. Aphids can breed in this environment. When this happens, they may appear as white spots. They can be identified by using a magnifying glass over the spots. If they are, then the treatment involves using a sucking insect spray to solve the problem.
- Leaves Curling Over
This problem is pretty common when the plants enter the end of the flowering phase. This is often due to deficiency in phosphorous. At this point, the plants may encounter problems in absorbing phosphorous and other nutrients. One way to solve the problem is to adjust the pH of the solution to 6.1 to 6.2.
Another possible reason for this scenario is low temperature during the night. Make sure to check the temperature during the evenings and see if you can increase it to make your plants more comfortable even in thermoperiods.
