First time grower here. I believe plants are behind where they should be for their age because of a couple bumps along the way.
Germinated the seeds in moist paper towels between plates and transferred to 4” pot organic soil. I started growing them in a small greenhouse tent with glowstar 150w burple LED, I was overwatering and couldn’t control temp and humidity. The growth was stunted and leaves were pale yellow about a month in.
On 12/2 I transferred plants to 1 gallon pots and used FF Happy Frog soil and setup grow tent and changed the light to Mars Hydro dimmed at 50% for a couple days then increased to 75%. I’ve gotten a better feel for water management about every 4 days based on weight of pots. I added nutes to the water on 12/11 at the above rates (wanted to start lite so I used the FF chart week 2) they really started to take off. I watered again yesterday 12/15 (no nutes) and today found spots on leaves as shown the in pictures below.
Any advise on what the spots could be, how to remedy and on my methodology would be appreciated.
