Hello,today these plants are 2 weeks old,they are not looking good and I suspect a ph problem,potted with 6,5-7 soil ph from bag+a little coco coir from a previous grow for drainage,the water is from the tap,used rhyzothonic at every watering 8ml at 2litres of water,last time used maybe 10ml at 2liters and the problems came
What do u think?

New growth looks good. Wouldn't break my head on it, unless the new growth starts coming in shitty. Cannabis plants can surely take a beating. My last pack of seeds came with a ball gag for the flower stage.

Now I watered pure tap water,I want to grow it without stress on the plant to get the best result but the problem leafs are getting dry as I can crumble them,that's not right for sure

just looks like a tad too much water to me.

Either that, or your tap water is terrible like mine and is killing the plant. If I use tap water (I have a well and my water is full of iron) my plants would be dead by the 2nd or 3rd watering

I may be unlucky)I let water to run off because I get rusty water at first I hope that's not the problem

The air is probably dry. What's the humidity in your grow space?

Edit: Ouch.. rusty water? I'd get a filter asap or switch to RO/distilled/purified water.

I don't drink from there,although I like it,very cold and tasteless,I mean I don't stay there all the time,forgot to look at but as water gets to the floor at watering and I don't wipe it off should be good rh

Also,is there a problem that it doesn't exist thermic amplitude?the heat in the room is always 22-27 celsius
