Small Plants

Just a quick 1 from me Get some cal mag in there pal if u havnt already 👍

nutes every time. 10% runoff, religiously. that runoff is fine for outdoor plants but not potted plants after that point or, down the drain. always water entire pot and wait for some minimal amount of drinking to occur before repeating. Once it's lost half its weight, probably okay, or if the top layer starts to change colors, that's a good trigger too. it will take forever for the 'next' fertigation if you insist on tiny plants in large pots in future. Dont be afraid of to up-pot an autoflower. the benefits far, far outweight the less than 1% chance of causing shock from an 'up-pot'. A transplant technically involved chopping through roots of an outdoor plant, and that would be stressful. Gently placing a rootball into a larger pot and covering it is not stressful. Key benefit being you can adhere to better watering habits described above withouy stangating water in your pot. try to go 5-7 days between if possible, and make sure to get 10% runoff. That tiny plant will take a while to drink off enough of the water to warrant the next fertigation. This only invites problems.

You should be feeding about every other day a 400 to 500 tds. It looks like you are experiencing slight ph issues. Your run off ph should be 5.8. 5.8 going in as well. You might need a good ph flush and to re add new feed to replenish coco. That's what I would do. Stop it before it gets worse.

Hey mate, I’m drunk af but it looks like your plant is “bleaching”. Add nutrients on every feed. At least the basics grow/bloom nutrients. Extras like cap mag silica you can feed them on every second feeding once a week. The bleaching comes from a Leak of N or a wrong pH. But since you only feed them twice i guess it’s the nutrients. Coco is not a natural habitat for cannabis and contains nothing they need. So growing in coco you have to add a lot nutrients just like you would grow hydroponic. I would use ATLEAST 2/3 of the nutrient amount they tell you to feed, but do it in every watering. Also keeps the ph in range the nutrients normally balance the pH around a healthy value, so if you feed them you don’t have to care about the ph at all. Good luck and success mate

It looks like you are overwatering them let the grow medium dry out fully so it is dry to the touch 10mm down in the coco and then water with nutrients

They're underfed. Give feed every other day at least. I usually push ferts every watering. Coco doesn't contain any nutrients naturally so you gotta keep them available.

Hey there, im not an expert for growing with mineral fertilizer, but to me it looks like your girls are hungry for some more nutrients, perhaps even some more water. They could definitely be a little bigger by now. But dont be discouraged, keep going they will be fine again! Good luck and happy growing! 🙌
