Yellow leaves! Burnt?

Mr Yeoh

Member
Hello everyone!

I m writing in Usa hoping to find help sooner than in my country topic.



I have a problem with yellow leaves, and the tips look burned.


These days I m doing some experiments with air and humidity and I might have fucked something.


Can you spot the problem? Temperature too high? Over or under water?



Thanks a lot

Sorry, I didnt finish the post.

T around 26/27 till last days, last 2 days is going around 28/29 Celsius

Humidity was around 50/60 before, now it s going around 40/45.



I m doing some work to test the extractor, I m waiting for the humidifer and some smart plugs to make all automated.

Thanks my friend
Too high temps, low humidity.Would go back to 50/60% and 25C
I think soil looks too dry?I would(once temps/humidity fixed),keep them for a few days on water only to recover from a minute "nutrient lockdown" that,I feel, has taken place

Since I m here I m just gonna make a summary of my grow!


First time I do it, so everything I bought is ''learn in progress''.
The plan was to grow 2 different strain: Pinapple express auto and Malana bomb auto by Barneys Farm.

Box is a 40x40x160cm (i believe is 16x16 inches x 13 feet)
It is still under construction but it s going to be a SmartGrowTent.

With smart plugs and the app, I can set the devices to turn on/off based on the termohygrometer data collected. (if the T is above/under, then start this plug; if the Ru is above/under start this plug).


Here some pics, it is still under construction.
Day 24 now.

What are you growing in? It doesn't look composted, and isn't being kept very wet. I have struggled with N availability using organic compost that won the category after hundreds of reviews.

As said, a grow food is needed. More is a subjective word though, and I we have no comparison to make. Only you have the answer.

Ok,I saw comment after posting.Is your soil dry?


I think is dry yes.
I give water every 3 days, but from what I heard I gave too much before..i was giving them around 200/300ml each since they were really yung..but when i give water the soil in surface is really dry till a finger and half down.

I give water in 3 times, to avoid lakes, and the water never leakes from bottom.

I had no time (or patient) to wait for pots arriving and I used a bin.

Thats my organic bin!

Autos!
Ok.What type of soil are you using?
They prefer a "light mix" for their rooting system to develop
That doesn't change the fact that temps/humidity are too high,underwatering!
The fix is a simple one,I wouldn't worry too much

I m using Canna soil, it should be good, mixed with some perlite i bought a side.
The yellowing was happening, but today was the first day with bloom light on too and the temperature spiked abore 30, I have to keep the exctractor on all time to keep it down, but if the exctractor is on the Ru goes down, and I m still waiting for my humidifer.
So, yeah, if the problem is T then I just can wait..if its food then I can do something.

Water them to the point that extra H2O is showing
Nutrients you stay away from for a couple of days!You don't know if the ones you've already given them have been absorbed properly
Temps 25C might find humidity coming up a bit with the watering, which is good till you get your humidifier
You leds might be too "big" for tent size, irrelevant if watering temps,humidity(50/60%) are kept at those levels
No nutes for now, heat stress,under watering is your problem
