blacksman This diary features my Northernlights auto plants, which I've just started growing. I've never harvested before and I'm not experienced. Don't consider this diary a guide. I'm writing here to identify any mistakes I've made, my shortcomings, and to get suggestions from you, valued growers. Thank you all in advance for your valuable comments. Stay high and healthy. On 5/10, I kept my NOTHERNLIGTHS AUTO seeds in a damp napkin and planted them a few days later. I added 'Great White' mushroom to the planted area. On 9/10, I added 0.5 mL of biobızz rootjuice. On 15/10, I added 'Great White' mixed with water. On 18/10, I added 0.5 mL of bioheaven, 0.5 mL of rootjuice. On 20/10, I added only water. On 22/10, I added 0.5 mL of bioheaven, 0.5 mL of rootjuice, and 0.5 mL of activera. On 24/10, I added only water.

blacksman Greetings from Week 4 -------------------------------------------- This week, I installed a new ventilation duct because I thought the tent was stuffy. Everything seems fine. When should I stop LST, and what and how much of each nutrient should I give this week before flowering? I'm open to any suggestions, my dear fellow growers.

blacksman Hi everyone, Hi everyone, there was a heavy bloom this week, and the pistils are now very visible. I increased the Calmag level because brown spots started to appear on the leaves of some plants. I feel like some of their growth has slowed down. I'll investigate the cause. I'd appreciate any advice. The photos show two different tents. I'm growing a total of 18 Northern Lights. Stay high.

blacksman I had a calcium deficiency problem last week, and I increased my CalmaG intake. I think it's improving. For extra micronutrients, I'm using Canna Mono.

Grow Questions

blacksmanstarted grow question 13d ago
I think my plants are short for some unknown reason. Are they supposed to be this size? What should I do to get a bigger harvest? How many weeks do you think they'll be ready? growdiaries.com/diaries/290736-grow-journal-by-blacksman

hey 👋 You still have a few weeks ahead of you, between 3 and 5 depending on the plants. Since you trained them all, their size doesn’t worry me; they’re not very big but within the normal range for autoflowers. However, you need to make sure they can all reach up toward the light like the one in the back, so no more LST, and you may even need to remove some stakes so the branches can straighten up. What you’ll need to pay close attention to now for a good harvest is nutrient management. Some are showing burn (photos 5 and 6), which means you should reduce the doses or even do a flush if the tips keep burning; others are showing deficiencies (photos 9 and 10), which means they need more CalMag to start with GL 💪

blacksmanstarted grow question 7d ago
What does my plant need? I watered two days ago to get it to grow and bloom, but there was no improvement. I watered it without nutrients today, and I'm open to suggestions for the next water with nutrients. Also, some of my plants have leaf tips curling inward.

curling inward and burned tips = overfeeding and your plant looks like that. so no nutries for her. just water, maybe with vitamins/enzyms but no NPK.... you can flush out your soil with some liters running trow the pot, but then you need a few days for the dryback or a very warm growroom/light to dry faster. the burned leaves you can remove - the will fall of anyway. i think you lose a week or two on all of this before it starts to go its used healthy way. on the other side you can also just ignore the overfeed leaves, leave them until they fall of alone, just flush the pot once and go your nutri way after 1-3 times just water until end of plant with lower dose like 50%. (or feed her near to toxic-death in hope that the buds still grow until they are ready and dont look on the rest of the plant ) ^^ just suggesting some options

blacksman Bu hafta bitkilerim daha fazla sarı yaprak çıkarmaya başladı. Sorularda verilen önerilere dayanarak Bio Grow kullanmaya karar verdim. Bir sonraki sulamada pH değerini kontrol edeceğim.
