The last week is the super stressful week for her. The temperature is over 35 C. But, she survives. Some leaves are becoming light colour and necrosis. I started to add NPK nutrient (BioBizz Fish-Mix). It makes the leaf colour better.
I still can not see the roots at the bottom of the pot. I feel I feed too much water and nutrients, thus roots are satisfied and not growing. But, I am afraid the underwatering problem at this moment. It kills her very easily with high temperature. Anyway, she grows not bad.

September 3: Watering 0.5 l. Fish-Mix 2 ml / l. EC = 1.0, pH = 6.7
September 7: Watering 0.7 l.
@HighTV, Thank you, man. The colour is very nice now. To take a better photo with good colour, I am thinking to buy a good light source for photo, not growing😁
@Black_Magic, This time, I tried to make night cool. I open the window a little bit at night time of the plant and make the temperature difference big between day and night. Maple makes leaves colourful under such the condition. I expect it works also for the cannabis.
Save yourself heartache, Aogaki, Spreading out the hotspot of an LED is key to achieving a successful LED grow. Raising your light may not help, depending on your circumstances but using a light rail light mover certainly will. You'll also be able to add more light to your garden without burning your girls and improve your yield. Good luck bro.
Hi Aogaki!
Looks like your plants are receiving too much light, seems too close 20cm away from 200w led...
Try to higher them up.
Normally with good soil like plagron you do not need to worry about the pH so much and feeding...
Just make sure when you switch to flowering you change to bigger final pot, that will help with soil pH.
Feed lightly with Epsom salt until leaves recovers!
I am growing some green Gelato also, will be following!
Good luck!
@Eauderay, Hi Eauderay, You are right. Now I am searching better distance, not far not close. One grower, @biggreens420, feeds pH 5.9 and has no problem on his plant. Sometimes, almost everytime, nature beyond me and teach.
Good luck too!
@Black_Magic, Yes you are right. Now she thinks she will try to smoke when she will visit next time. And she will decide to stop me or smoke together. I have to prepare ice creams, sweets, nice comedy movies, music, etc. for the next time😂
@BigDaddyK, I have the tray for the pot. But, measuring runoff is difficult. I saw some guys use metal shelf between pots and trays. I am planning to do so.
@BigDaddyK, Yes, I want. In the last time I tried to use a straw and mouth to bring runoff. I felt I am a little bit silly😅. It is very high EC. Probably many stuff is coming from my mouth😩. I think the next growing setup for measuring runoff easier.
@Black_Magic, I watered and checked pH on the last night. I set the pH of the solution as 6.1. The pH of the outcome water is 6.5. I set the pH as 6.7 at the last watering. I can guess the pH is over 7 (7.1?) with the past setting. It is not so far from the safety range of the pH of soils. But it is outside.
This morning she looks no damage of the big pH shifts. Thank you again😁
@Black_Magic, Yes, I should check the pH of runoff. And your opinion fits for me. The schedule of plagron suggests me to use pH5.9 at the middle of flowering. I guess plagron soil makes pH a little bit high, or very high. Anyway, I have to check run-off not only the water before feeding.
Thanks a lot!!
