STAYINGONMYMAINCBATORUNTWOstarted grow question 6y ago
Anyone know what this is? It’s only on 4 of the bottom leaves of my purple lemonade! I plan to give them cal/mag on their next feed to be safe but knowledge is power?! And I would like to know for certain!

What is the PH of your substrate? Looks like needs some calmag to me, however could be other things depending on the PH.

White Spots on LeavesJust trying to figure out if I have a bug problem. I'm a week and a half away from harvest and started seeing these little white specks on some of the pot leaves.
And if this is a bug problem, how do I treat it this late into flowering stage?

Foliar sprayI want to introduce some epsom salt foliar spray for Penelope and two clones I have in veg at the moment. From what I understand around 200-250 PPM is a good range. What is optimal PH for foliar sprays. How often can it be used?
Or what can I use as a habitual spray?Leaves. Other

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?

Yellow leaf septoria?Hi, I think some of my plants have yellow leaf septoria. How best to treat this? Should I consider removing leaves, plants or maybe starting again.
It might of been due to my constant misting to maintain a high humidity at the start or I was also thinking fungus gnatsWeek 2
