Im a first time indoor grower, but have grown outdoor for many years, so please, assume i am a complete newb.
I am having an issue with what was a really healthy plant just a week ago.
I’m 6 weeks into veg under a 400W MH. I’m growing in soil and have been using a organic nutrient mix of 4-3-3. My temps and humidity are under control. Im on a 18/6 light cycle.
This problem is clearly some type of nutrient deficiency, but I think it may stem from a low PH issue, as I was not monitoring it.
The problem seems to be more toward the lower/older leaves, but seems to be climbing quickly. What is the proper way to proceed? I have purchased PH equipment to assure my water’s PH will be good from now on, but will this be enough to save the plant. I intend on using her as a mother plant.
Thanks for all the help!
