Thrips or nutrient issues?
Aqueminianswered grow question 3 years ago
That looks like a cal-mag deficiency to me. Every time my plants do that, I increased my cal-mag and the problem would stop. The damage already done will never go away but new growth and old growth wont do that anymore. Also helps to check pH before making any adjustments just incase your pH just fell out of its uptake zone.

Looks like a calmag or potassium issue to me...I'd drop the calmag to half that, and push more nitrogen if in veg...I'd also hold back the pH to about 6 to be sure your not getting nutrient blockages

With starting flowering I would suggest checking runoff ph is always first. If in range then upping your potassium and phosphorus levels a lot will help. This could be potassium deficiency is what it looks like to me. Also reduce your nitrogen level to help promote bud growth. Good luck and happy growing 🌱🌱🌱

First grow mid-flower pest?Help! Is this pest damage and what kind? I have about 100-200 ladybugs in the grow tent, and have for about a month now so I would be surprised if it were aphids. The damage is not extensive but there is a little here and there. Cant find anything under leaves.

There are no webs, but they're still present and you can see all the white marks on the fan leaves.

Mites?Hi. What are these? Slow crawling, not fast or jumpy, about the size of this period . They swarm by the thousands after I water. Plants are doing great. I hit them with CannControl and Lost Coast, population has reduced a bit. I’m leaning towards soil mites. What do y’all think?

Found 2 bugs. A fungus gnat and a white crawler.The white one had legs, but seemed little bigger than the gnat, maybe a gnat transitioning from larvae to fly? Gonna let soil dry, and apply stiky traps. You guys think its enough? Only found two maybe a third flying around. Should i apply any other measures?Other. Bugs
