red/brown/white spots on my blueberry gum already flowering

I hope i can get some help for you guys on this one as i have gotten before!

ok so a couple of days ago i picke dup my plant and accidentally bumped it onto my light fixture (plant touched the hot glass on my hood). Next day i noticed a couple of leaves seemed to have burn on them, it looks like atcual heat burn and i also noticed half of the main cola TOP bud seems burned only on one side so i thought i may have caused a little damage or what not. Today i got home to find some more of these reddish brown spots and from looking at these problem guide threads and looking at this picture it seems like phosphorous deficiency (from the picture)




can anyone help? here are pictures of the actual plant, heres the best i could do, i didnt want to have my light on too much since right now its night time for them.

or could it be extreme Mg deficiency?

Sorry, wish I could be of some help.. I'm a new grower. Best of luck though!

Ok its in bloom so I' d guess P.

Sometimes it's really hard to help with a diagnosis because so many problems look the same even though they are very different.

I feed them GH- FloraBloom which is 0-5-4 should i double in dose or go find a solution with P only?

hi mate,

I've grown out some BBG aswell. Mine dropped many leaves durring flower but the colas remained healthy. The def you have in your pics looks like the defs I got with my critical jack autoflower, with the sort of burnt patches right up the plant. I'm pretty sure that the bump against the light will not have caused much damage.

When I had these same deficiencies with my critical jack auto I narrowed it down to an Mg def like 100degrees (kyuss ftw) has suggested. It did turn out in the end that it was my ph to blame, and not lack of that nute in the soil. peace

thanks a lot for your reply! Im going to water tonight and check runoff water PH, i dont have a soil tester at the moment.

I'm a poor grower really so have never been able to afford one of those nice electronic testers. I have heard that you can get a cheap soil testing type of kit that is almost useless. I go with the chemical ph tester, was really cheap and does the trick. Not very accurate but comes auto calibrated
