“Could you please help me identify this and the best home remedy and reasonably priced product I could use to kill it? It is shishkaberry grown mostly in the sun in Miami Florida in a pot but I supplement it with a 25 watt LED light. I used fox farm soil as a medium and use their tiger bloom big bloom and big grow plant food. I tried spraying a milk-water mix and I tried apple cider and I tried Ajax. What else can I do? The growth is appearing from the ground up. The top leaves look great.
It is a shishkaberry that is beginning to flower. I am growing outside in a pot in fox farm soil and I feed it fox farm big bloom and fix farm tiger bloom, each a teaspoon every week. The weather is very hot; 85-100 degrees F but the temperature is starting to go down now to the mid 70’s. And the humidity is 90 to 100%. All grown outside, no CO2 tank and no air conditioning. I do use a 25 watt LED growlight from 4 pm to 7 pm each evening. Please identify this flaky white stuff and please identify the best: A) home remedy and B) the best retail product. I have already tried spraying a milk water mix. Then I tried spraying apple cider vinegar. The milk seemed to work for a four days. Then it came back.”
I am by no means an expert but if it flakes off of the leaf and the leaf is intact - might it not be salts a build up and it being expelled through the leaves? You did mention feeding them weekly - if they are pot grown I would think that excessive - I grow indoor and feed bi-wkly and only during flowering. The soil should carry the plants till flower with enough nutrients.
I’ve noticed a dew on some of my plants sometimes and I did not water - this could be them breathing and with yours they could be trying to rid themselves of the excess. Again I am far from an expert – just my opinion… I would flush the soil and see how this goes first.
If it is powdery mildew the milk solution will work good but you will have to keep reapplying every 3-4 days to keep it in check…just keep an eye out and if. You see a spot hit it with the solution…if bad give her a bath in it (spray her good all over) milk is a natural fungicide and won’t hurt the plant… actually good for the plant and I ffound milk solution to work better than the vinegar solution
It looks like nuts splash to me first picture
Second and third almostlook like slug trails ?
Is the whole plant being affected or jut the couple leaves you posted ?
Maybe post a picture of the over all plant also
