Got some other problems.

[Vik]

I think this is a deficit of phosphorus, but im not sure.
I gave to the plants some micro nutrient that contain phosphorus inside, leaves keep look like this..
The new little leaves started to burn the tip and the colors are like jellow/brown.
What could i do whit it?

First,
Leaves do not change back to normal, as long as new ones don't form.
please tell us what medium, lights, what height from plant, nutrients, pot size and a pic of the whole plant

Thx for your answer

Well, the medium is like an universal soil, i've checked, it has ph 5 at the moment, the plant it's 40 cm height and the pot size is 25cm for the diameter and 25cm height,
For the nutrient, i use ox blood for the nitrogen apport then Biplantol Vital for the micro nutrient (potassium, calcium,iron, phosphorus, magnesium, boron, germanium, copper, manganese, uronic acid)
I use two led lamps whit 100w power that have 890 lumens each one.

u can also see the new little leaves on the second pics, idk whats going on here..

Ok, always check for bugs...
Because some look like bug problem.
Some could be water burns/light (heat issue)
PH is on the low for soil. Can you rase it to 6-6.5?
The girl behind has issues as well, right?
@Mr. Krip @InTheShed @Pennywise
All with lots of experience.. They can clear it out in no time

Ill check for bug, but i think isn't that..
Yeah i lost hope whit the other girl.. just try another one. They just started really well, than, idk why, goone.
I try to rase the ph as well but, it keep stay low and if i add to much nutrient there will be another problem. So, if u know some product to use, would be nice know it.

Sorry for my bad English, isnt my native language.

Nice!
@Mr. Krip @InTheShed @Pennywise
Really hope they can give me some advices, i really want to learn, i love growing, and never had so much problems..

 

[Mr. Krip]

PH of 5 is way too low! PH in soil should be around 6.3-6.8:

Your English is a good as mine ... Forgot to post this earlier.. Sry...

 

[Chris Scorpio]

The Biplantol Vital is designed for flowers it appears

That and the low pH is toasting yer girls

Orchids are not Cannabis, really suggest a Cannabis specific nute line, or u will have constant battles

pH pen is very very important, get one of those as well


Good luck

You're right, i have to buy particular nutrient stuff..
Did you have some advice for, and, where could i buy it? (Online shop pls)

It could be the water ph to low that bring the soil ph low too? I'm considerating use only distilled water whit minerals added in a second time.. what do you think on this guy?

Ahah thx bro

Yeah that's what i need, but now i have to buy some stuff to push it up..
There are products that have'nt nutrients in it, and regulate only the ph?

 

[Chris Scorpio]

No clue what is available in yer country
Lots of Cannabis nutes, search what's in yer country and post them here

Also get a pH pen, and pH up and down for your water

Use RO water, distilled I don't think is good, I may be wrong, or spring or drinking water. Yer tap water may be fine but u need to test it

Yes, there are products the help adjust PH in soil. Dolomite Lime is a common organic way to raise PH in soil. Also, ground eggshells & oyster shells will help reduce the acidity in the soil.

Distilled water is fine!!! Like R/O, it will measure 0 PPM on a TDS meter.
