I started one about a week or two before the other one, so I will be logging from the younger plant's time. This is my first more professional style grow with a nice light, tent, and ventilation. Light is turned down to 5% and kept an appropriate distance. I use a lux meter on my phone. The smaller plant is getting about 7,000 lux and the bigger one about 9,000 lux. I will be LST-ing when I put them into 1 gallon pots.
I ended up repotting the bigger plant. I think it is actually about two weeks ahead of the other plant. Judging by the roots, it was time. People on RIU cautioned me that autos have to be repotted early. I don't think I was too late, but we shall see!
@Jeff78, I will keep this in mind, but some folks on Roll It Up would disagree with you. I'm going to try solo cup --> 1 gallon --> 3 gallon and see how it goes
Hang in there. It's all good. Something else to consider is using a medium you don't have to ammend. Most premix organic mediums will have adequate nutes for 60ish days and then you feed it right at start of flower and you're golden. It's a learning thing and you've taught me something.
You may be able to save the older one too by attempting to prune the roots and feed her dechlorinated tap water. They could have nutrient lock as well. If you need some seed in a month or so direct message me and we can figure something out.
Adding NPK might help at this stage have you checked the ph of the run out?? If the ph in your water is off they will got into nutrient lock out and it won't matter what nutrients you try they won't be able to absorb it
I hope you manage to get the issue sorted
Hola hermano! Lamentó el amarillamiento de las plantas, como te comentaron e muy probable que tu suelo y Tenía sales y al agregarle más se bloquearon las raíces, tienes que hacer un riego abundante de agua previamente medir ph y ec y luego recoger el tu de la ecorrentia y medir de nuevo ph y ec para saber cómo e encuentran las raíces,
Por otro lado porque dices eso del jugo de limon? Cual es el efecto negativo ?
