What is it

[grower7155]

Hey guys. In my fifth week of flower and I noticed some spots on one of my plants. I'm growing in biobizz light mix and feeding them every watering, about once every three days, with canna nutes(Ec 1.5). It would be great if someone could tell me what they think it is. The most important thing for me right now is knowing if it's a deficiency or burn so I can know if I should step up the nutes or give em plain water. Thanks

you need more calcium and magnesium.

it's iron... like P.B.L said get some cal/mag but with iron in it too.
most cal/mag has it. but check to be sure....

check your PH too it may be off and just so you know I see a LOT of people having problems with that biobizz soil.... it may be user error or the soil maker??...... who knows.


peace
