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 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

translucent pest in soilHi, last watering I've seen tiny translucent insects (about 1 mm) emerging from the soil. They are fast and can jump like a flea. I assume they live in soil. What are these little monsters, should I worry about them and what should I do ? TIA

What and why?What are these and do I need to address it?
I'm a couple of weeks in to my grow and just spotted these little critters when I was cleaning my run off saucers. I'm guessing there's more inside the soil are they harmful to my plants?

Insects !?!? Help please first guerilla growI've noticed some burn-like spots on my baby. It starts from the top leaves. I had some issues with insects already so the plants didn't have the easiest life so far. Is it the nutrients or I've got some uninvited guests ? Many thanks ladies and gents !

Identify bug / larvaAny idea the bug / larva? Reapplied insecticide soap. Might need to change plans if she starts flower before they're dealt with. For additional reference see diary, and also I have tomatoes and peppers in the same "garden". Pics are at 60x magnification - first 2 on plant.

I'm under attack!I think I have a solo predator here guys! The damage is localised to the left main branch in 2 places and the top of the main cola and just below.
I have made up some washing up liquid pesticide and drenched the whole plant and vegetation around.
Could it be something else?
