Need help (yellow brown leafs)

[Zinari]

Heey, I wonder if anyone can help me figure this out Tryed to find something like it but hard because the pictures I found I mostly 20 times worse

Iv’e read so many different things I’m unsure what it can be
They are both in week 4 stage
They still grow pretty decent and the problem don’t seem to affect all leafs I’m not sure if it’s nutrient burn or if I managed to spill some water-nutrients on them but does anyone know what it could possibly be?

I also have temp around 23,5-25 Celsius and a 1000W kingled grow lamp but it’s 130-140 cm above canaopy I use T.A grow kit (gro,bloom,micro) and calmag

I think I figured it out not 100% sure though but might be overwatering some leafs tend to curl but goes back to normal

You have a few things happening here which is a tip off that you possibly have root issues.
What are you growing in, soil? coco?
Parts look re-vegged. What is your light cycle and what kind do you have?
What and how do you feed / water?

They are in veg phase still I use coco and 30% perlite I water every third day or when soil is dry 18 hours of light I use a 5 ml needle to water with so I don’t get to much water at 1 spot , I dose around 1,5 ml gro , 1,5 ml bloom and 0,5 ml micro in 1,5 liters of water

They recently developed pistils also I have 3 plants with different strain and they all react differently one of them had issues during germination the root went above the soil while the leafs grew under but I managed to replace it correctly I don’t know if that has affected the plant somehow

Here is some other pics aswell each one is different the first one is having most issues (northen light) and than the second have a few aswell (gorilla) and my fat banana seem to thrive however

Basic Watering

Marijuana Watering, how media, pot size/shape and environment affect it

Ok lots of posts on how to water plants. So I thought I would put together a thread on how different factors contribute to different results that ppl see. This will be a long read based on my personal knowledge, opinions, research and others work to consolidate information for our members. I'm...

Watering COCO

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...

In Coco, so it's likely watering / feed issues.

I can’t be the only one with a wtf gut response to this. Unless you have huge pots you can’t overwater coco and if you aren’t watering enough to get run off every time then you are building up salts. Unless watering with a tiny syringe is some kind of cathartic activity, I’d step it up with something on the order of a gallon bucket if you want to stick with hand watering.

The volume of nutes doesn’t matter half as much as your ppm/ec. Ppm and Ph meters are cheap as dirt these days and are a must for any kind of hydro grow. Flood it and let it drain. Never let it get to the point in which it looks dry

It is hard to tell how big your pots are from the pics. 3 to 5 gallon bags?

I strongly suggest reading aquaman’s thread on coco watering. I’m watering pots just under a gallon every 90 minutes now. I’m near harvest on some pretty overgrown photoperiod and am quite happy with the results.

Yeah haha trust me I was reacting the same after I saw the guide obviously I was under feeding my plants but I’m following the aqua man guide know and I don’t let the soil dry out anymore and hopefully it won’t affect the plant overall. First time I grow aswell but I should have read more about coco instead of focusing only on the phases and grow cycle however I’m gona invest in a ppm asap I got a ph already and try to be as accurate as possible 5,8-6 I read somewhere that in coco you should try to have ph of 5,8 not sure if that is correct though

My pots are 4,5 btw might be a bit big idk why I picked that size rather than 3,5
