My first auto

Your plant is looking good, its nothing to worry about right now, As ezz has pointed out slight N tox but nothing that will prevent it from doing anything. FFOF is great for photos and HOT for autos. a 50.50 mix with generalized potting soil is a good idea/option. They should not need to much CaMg at this point, FFOF is a soil and has some calcium in it, I would keep up what your doing and lower back on CaMg. It will need other feed in a few weeks time, keep an eye on them for when its showing you its hungry. FYI: We will not be notified of any reply or tag [@] in the questions part of the website, if you need to reach out with other information use your DM "direct mailbox" in the bottom right hand corner of the page. it looks like a little paper airplane icon. Best Of Luck!
