hey peeps. so my plants look pretty happy after transplanting (first ever grow):
However, I noticed that the bottom leaves are getting brown spots:
For the record, I am using FFOF soil. I don’t see how it can be a nutrient deficiency if I just transplanted it into all this new FFOF soil.
My pH is fine. Using tap water and it’s 7.2 but I use ph down to bring it to 6.5.
Was thinking light burn might be the culprit so I raised the lights from 20" to about 22" above. However if light burn was the reason then why would only the bottom leaves be browning and not the top ones?
What do you guys think? Any help would be appreciated.
