here are some pics. they have been acting this way for the past couple days, thought it was heat stress at first cause I had a heat wave in my room but then these spots started appearing. I have looked at ton of pics and can seem to determine what the right approach is.
I am growing in MG and I know it's not the best stuff in the world but I haven't encountered an issue till now, they are about 3-4 weeks old from seed. I just can't afford to grow in fox farm, there is only one place here that has it and it's 27 bucks for a small bag
MG has three versions of garden soil; no fertlizer; 3 mo time released; 9 mo time released. Each of these will contain different amounts of nutrients - and will require a different plan for supplementing.
it is MG 6 month feed potting mix. my pH is staying between 6 and 7, i just fed yesterday with a small amount of alaska 5-1-1 and a little molasses. nothing else has been given yet. this didn't happen till I had a heat problem in the room
I am running 48 2700k cfls
and have great ventilation with a temp of 75n and 85 day
I have another plant in flowering that is in the same temps or higher and havent had an issue with it as a matter of fact its budding great. Same mg soil with no nutes till flower. I dont think the temps are whats causing this. I did at first because of the couple days of sahara but thats well in control. It almost looks like a manganese problem. Do you think flushing and dropping the ph down might help? I am almost considering repotting in different soil.
