That soil is looking rich. Have you used plagron batmix before?

The bat guano and EWC will give you a bit longer than that. You planning on using any other amendments to carry you through the rest of the grow?

Plagron Alga Grow (NPK: 4-2-4)

Probably won't use this as the soil is fertilized for 6 weeks.

Plagron Alga Bloom (NPK: 3-2-5)

After the 6 weeks I'll start giving them this.

Plagron Green Sensation (NPK: 0-9-10)

I'll start giving this in the third week of flower until 2 weeks before chop.

Haven't had time yet to work on popping the domes off and making my case ready for flower (lightproof). The NL has been put at the left and the OG Kush to the right, because the NL grew taller and took away a substantial amount of the ventilation the 80mm PC fan provided.

I've also topped both of the plants. The method I used was probably not the correct one, since they looked really stressed right after I topped them. They started drooping and looked lifeless. On top of that the weather has become very warm. Temps went up to 32°C (90° F) on the hottest part of the day in my case.

The leaves are starting to show deficiency's, probably magnesium deficiency. I think the water I have been using has too much salts in it, locking out some nutrients. The pH of the water was 6.7 last time I gave them water and the runoff was 6.6.

As you can see on the pictures, the leaves are still drooping and the lower leaves are yellowing. I'm going to buy distilled water tomorrow and give them a flush, hoping the problem gets fixed. *fingers crossed*

Mr. Sparkle

Ph should be fine, as for magnesium deficiency if it is one dolomite lime works great for that and stabilizing the ph at the same time, 1-2 tablespoons per gal/4liters of soil/mix.

Topping shouldn't of caused the drooping, so the question comes up how you're watering, too wet, too dry ?, how heavy are the containers ? Also the drooping could've been caused by the heat.

Also i presume your going to flower cycle shortly or are already are ?

Last time I watered before they started drooping was 3 days beforehand, the drooping started a couple of hours after I topped them. I think normally topping shouldn't be an issue but maybe my plants were unhealthy because of too much salts in my soil.

I've read in this thread (CTRL+F: "have sodium"):https://www.icmag.com/ic/showthread.php?t=11688

that too much salts can cause droopyness and magnesium deficiency. I didn't really care to check at first what kind of bottled water I was using, but one of them had an EC of 1.6.

Amount of minerals in the bottled water:

Calcium: 243 mg/liter
Magnesium: 77 mg/liter
Sodium: 54 mg/liter
SO4: 675 mg/liter
HCO3: 295 mg/liter
Chloride: 66 mg/liter
Fluor: 1.3 mg/liter
Potassium: 7 mg/liter

I water around every 4 days at the moment, the size of my pot is 2.2 liters and there's a substantial difference in weight before and after watering. I don't think over- or underwatering is the problem.

Once those two branches get some length I will LST them and switch to flower soon after. Anyway, I will flush them in a couple of hours and hopefully the problem gets fixed. If you have any other idea what it could be, let me know.
