Dark spots on leaves
daveHHstarted grow question 3 years ago
One of my girls got dark spots on her leaves. Is she ill, or is it too hot, or is the humidity too high? I gave them every second watering all those fertilizers 1ml/L. Could someone help please? I cant reduce the temp without this small climatizer (which is filled water) see pic

you are not giving them any grow nutrients? you know what fuck the temps, dont use that cooler because it raises your rh too much, under leds 29-30C is just fine. keep feeding as you were but also add grow nutrients at the same ratio as the bloom. plants use a lot of nitrogen in every stage of growth. something like 2-8-6 cant sustain a plant. thats too much phosporus and not enough N and K. at least shoot for a 1-1-1 ratio between N-P-K.

Raise the dosage to 2ml/l from everything the faster the better.
You Ph is out of range , your plants are hungry,
Yess they need CalMag too, but raise this just to 1ml/l
Jeah to much heat cuz they can't handle that temp without nutes and co2,
nd your humidity is too high at this stage.
Use Alga mic 2- 3 times a week to spray the leaves it will help recover faster and will not make it more worse.

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

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.

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? 😥
