Flex1started grow question 4y ago

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.

When should I put the pellet in the 5 gal pot??I am currently growing a tangie'matic with "a pot for pot" grow kit. At first the seed germinates in a pellet. Then it says "put pellet in 5 gal soil mix after 10 days or when the third set of leaves matches the second." I did it after 10 days and this happened.

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad
