Could it be caused by heat?
Running 32c when I got back before I turned on the AC! It gets really hot in this part of the world and running an AC is quite expensive! Any ideas? I don’t know how to tag @Glitch @LiesGrows
Help please

My cot are yellowish
The cotyledon turning yellow is normal. They provide food for the plant until there is enough root system to take up nutrients. yellowing just means the plant has nearly sucked them dry.Have you come up with a feeding plan yet?

Yes, ilgm gave me 3 stage fert so I’m going be using that! Can’t get my hands on a lot of things from here!

Just a quick question. Are your lights on at night or day? 89° is high but bearable by cannabis. If lights on at night when home and using ac for comfort the tent will benefit from the lungroom temp you keep for yourself. Can drop a good 5°f . This is me assuming you have an enclosed grow area lightproofed. My geographic area is hot and super dry summer. I have had summer runs with temps hovering hi 80’s low 90’s whole grow. Just replaced ac so hopefully lower this year but point is can be done and done successfully if cant get down to low 80 hi 70. Extra watering. Lights at night. If auto I also do a 6/3 light cycle allowing a 3 hour cooldown every 6 over 18 straight hot. Also used for veg photo in summer. We cant always be spot on but cannabis is a weed and gives us pretty wide environment variables if we cant hit perfect. Just my thoughts from when i used to fight it. Now I just adapt and overcome without stressing. Dome those seedlings and they wont mind hi 80’s.

Lights are on 247 and my regular temp here is about 32°c. They are autos too
So they good to go under such Hi temp?
Would they still have some quality in them?

So does this mean I have to start watering?

With fert I mean

No need for 24/7. 18 a day is fine even broken up in a 6/2 or 5/3. You will benefit from less electricity. Temperature stabilizing to an average 5 or more lower than getting right now. Easier to control lung room which will drive tent temps more than anything… just my thoughts. I have fought your fight and surrendered to adapting over fighting a losing battle. As you get dialed in you will smooth out and find your sweet spot even if it doesnt meet a number suggested. Not once in my life have I been able to control mother nature outside and for some reason cannabis grows great out there…grin

Dome them and wait to feed. I think Glitch is asking for when they are ready. Weeks out.

What Storm said. I’m not the most help with environment. My answer to things getting too hot in my grow was buy a bigger A/C. I doubt your ready to feed yet. It’s just good to have a plan in place before hand. How long before you need to feed depends on what kind of soil you mixed with your coco. Do you have an EC/PPM meter and a PH meter?

Hahaha none of those!! Im using Coco and it would be impossible getting those where I am
! I just have to improvise my way through everything!
So I’m using distilled which is neutral

Welcome aboard… 
It will be very challenging to grow without a meter. Especially in coco. The nutrient solution needs to be around a PH of 5.8 to 6.0, if it is not the plant will not be able to absorb certain nutrients. Distilled generally is around there, but will absorb elements and drift will begin quickly. If this is your only option keep it sealed as much as possible.
The EC (electrical conductivity) tells you if your feeding the plants the right amount. To much will burn them, to little will starve them. Again, if you don’t have access to a meter, stay vigilante on your leaves and what they are telling you. Referencing a guide like this may help.
As far as heat, while 32c is not optimal, it will work but it will effect the yield and quality. If available to you, a mini-split type A/C is generally cheaper to operate. If possible, build a small, well insulted and sealed lung room, which will be much more efficient to maintain the climate. For temps, humidity and air flow. When the plants start getting bigger, they transpire a lot of humidity, if this isn’t controlled they will mold and rot. Make a plan now.
Once the cotyledon start turning yellow, it is time to fertilize.
So you will understand, if you have questions for us to help you, and you eliminate the answers as a possibility to you, it will be very hard to get additional information. We will try our best, but most of us don’t face those challenges, we can tell you what they need, it will be up to you to provide it one way or another.
Geez you are an all in one package!! Thanks a whole lot, I appreciate this piece of knowledge!! Thanks again

Living soil may be a better option in your situation. It allows the microbes, bacteria, and fungi in the soil to handle the ph and salinity of your soil. You just topdress every other week and water. You can also make a decent living soil out of just about anything. You just need 1 part soil or peat, 1 part aeration, and 1 part organic matter like compost or worm castings. You can feed it with home made compost and or worm castings. Do you have anywhere in your area to get agricultural or farm supply. I grew with a similar method for many years with great success. It doesn’t really require any special equipment just a pot dirt and a plant. You could just do coco, do your best follow mixing directions and water daily and it can work out very well too, but you may be limited in your ability to respond to issues with a limited availability of tools and nutes.

Oh almost forgot, I’m happy to help any way I can, but if you need to get my attention I’m @Gl1tch with a Number " 1 " instead of the letter " i ". Glitch is someone else.
The company that makes your tent sells testers and they’re cheap.
Sorry for the late reply but impo yes 32c is to hot for seedlings thats what like 90f i like my seedlings around 75-80f

Don’t look too happy and
And I’ve decided to go with soil!
Lost a cot, could be heat or could be light but imnot gonna let it get to me, I did my best to save her
A new one just came up, I hope I don’t lose her too!!
Hello @gl1tch @liesgrows
What kind of testers?
