SOIL The 27th day of flowering

[lin091117]

Plants don't look alive in the 27 days of flowering. The leaves are yellow in the order of the above picture. They are watered indoors in a 5-gallon cloth bag. The temperature of turning on the lights is 70-75, and the temperature of turning off the lights is 60-65. I have tried many methods, but they are useless. Can you help me to see what the problem is? Thank you very much. Thank you

What about the nutrients? They are low on nitrogen and phosphorus but it may be a ph issue, other nutrient blocking nitrogen, or plain deficiency

I agree they look like they're eating themselves and are hungry

Have you checked ph in the root zone? How about your water ph, what nutes are you using, how much if any?

probably a problem with the PH level of the water. Make sure it is around 6.5 for soil as this is the happy medium. Also, if you are adding liquid nutrients make sure you test the PH after they have been thoroughly mixed in the water.

If you aren't checking the PH levels then you are likely too high or too low. Go online and get a PH meter if you don't have one. You can get a decent one for about $15...just make sure it's properly calibrated.

Okay, thanks.
