P deficiency (95% sure) help request.
Arandhirstarted grow question 4 years ago
P deficiency. I cannot measure soil PH but it's "Biobizz Light Mix" and I use suggested BioBizz nutrients. Now is cool here and the temp range is around 17-13 °C. There's a method to fix the issue? Should I heat the box?

You are giving too much nutrient! You are experiencing a nutrient lockout
Have to give nutrient and water 2 or 3 times first, then 1/2 dose max and they suggest biogrow until the end of flowering i will use it the first 2/3 weeks of flower and then cut it out
Arandhiranswered grow question 4 years ago
@MangoDudu I am going to follow your suggestions. I can trigger exhausts and fans without problems.
If I understood well I have to use only water for 2/3 times then add just half dose of BioBloom and TopMax. Is it correct?

The temps in the day are ok, in the night may turn off the induction fan and if u use a controller to dim the exhaust will help also a lot

What have I done wrong and right?I'd love some critical looks at my plants, there are two in this grow. With only a few weeks left, I don't think there is much I can do to really improve things. But, please look at my pictures and tell me what you see wrong and what I should have caught. THANKS! 🙏4 years ago

Possible overfeeding nutes?Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.

Outside Transplant NutritionI am going to be transplanting to an outside location. What is the opinion on needing to fertilise the soil before the transplant? I’m under the impression that if the area is littered with brambles then the soil is already ideal?Week 3

Help needed - harvest time?Hi, I'm now in week 12 and I feel that after the flush my 2 vertigo stopped developing. They also have a lot of leaves with some mag issues. Not all the pistols are amber (70%). Also, the trichomes are not all cloudy. I'm not sure but I think I don't see changes anymore.
