Stickanswered grow question 6 years ago
Hi there! It looks like you got some miners, digging into your leaves...I'm more than used to them! First, always remove affected leaves if it's possible (3-4 a day max). Secondly, find some neem oil, mix a teaspoon of neem oil with 1L of hot water, let the mix rest and get tepid, then use it as a foliar spray onto your plants at night. These little bugs hate neem oil, you'll see the invaders dying one by one ;-) Finally, you can try some products to protect your leaves against such invasions, I use BioBizz Leafcoat, which is basically a shield for your leaves. Hope this helps, keep us up-to-date and happy growing!

Yep leaf miners. While annoying, they are not really dangerous, unless you have a real infestation. They are a kind of larvae of small fly. If you have just a few affected leaves, you can either pluck them or if you look closely on the underside of the affected leaves, pick them with a fingernail.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Spotty/Blotchy Discoloration on leaf.What is this spotty/blotchy discoloration on this leaf? None of the other plants have it, it didn't brush off when rubbed. Hoping it isn't a mold or a pest...I have been keeping the humidity around 65% with good airflow, but I'm wondering if it's time to bring it down to 60%.

Still K deficiency?I fed some flower fuel to plant 1, half strength, and the discoloration got worse! Some leaves almost look like cal deficiency so I also sprayed foliar with calmag, just now when I got home. Is this still looking like a K deficiency? If so, should I feed it again or wait?
