My seedlings are 2 weeks old today & I noticed the cotelydon leaves on one plant was getting more & more yellow by the day. I read this was normal they eventually die off. So today I noticed the true leaves getting yellow tips & the cotelydons were completely shriveled. So now I’m thinking this has been a nitrogen problem. But I’m growing in fox farm ocean forest and I know they should have plenty of nutes to last a while, I water them with distilled water and I ph it to around 6.3-6.7. Is it possible the soil has gotten to alkaline somehow and the plant can’t absorb the nutrients because the ph of the soil is off ? It’s weird because fox farm soil is already ph’ed to 6.3-6.8. So what can the problem be?
