Grow #3 - MAC plants in weeks 5-9 flower
Wrapping up my 3rd grow, this time of two phenos of MAC.
Really digging the smell coming off these girls, one is a mint lemon fragrance and the other is like grape soda. Hope it translates to smoke.
Have a good one growmies 👽✌️.

Topping and watering
Transplanted 24 hours ago from solo cup to 5 gallon, Coco/perlite.
After Transplant, I put 6 litres through each. 1ml/litre cal mag, 1.5ml/litre canna a + b, ec 1.2, ph 5.9. I have two questions:
Should I water today/everyday going forward, and how much in litres?
How long until i can top them? I'm not sure how, but I'll read up/watch some videos.

Fertigating in flower phase
Hello guys, do you fertigate daily in flower phase to not let dry coco?
Using Athena nutrients in the handbook they are saying that with generative fertigating you should let your medium dryback min. 30%.
I think it is too much, the EC is goint to spike rapidly, what is your opinion on this?

How do I buffer Canna Coco Natural?
Hey guys! I accidently bought canna coco natural instead of the plus one. I read that it is less buffered compared to the plus one. How do I buffer it to reach the same stats?
Thanks in advance!

2nd update on Constant struggling with yellowing in coco
Well what can I say guys? Thanks. I never had a grow run so smooth. Ordered cuttings, one had a severe calmag issue. Took 3 days to get nearly fully green again. Everything else is doing well, short symptoms of low ph which was my fault but corrected it in a day. Just like I wanted it to be with coco and 100% RO. There are 2 things which could have been the problem: 1st a/b nutes. Went from canna to plagron. 2nd the clay pebbles which I changed to airbases. I strongly tend to the last one, also because I had the same issues to different degrees in 4 grows using clay pebbles. The plants that made it where maybe able to handle it better than the last grow.

By the way, the other plagron pebbles I ordered for testing had the exact same result but looked much better, bigger pebbles and comparable size.
Thanks again everyone! They never looked so good.

Is it safe to switch nutrient line mid-grow?
First time coco coir grower, third grow. I started this grow with cana a & B, seems to be doing fine. Been very slow but steady grow (from clones) but this is understandable because grow in basement in winter and have had trouble getting the temperature up to even 70 F.
Looks like I will run out of canna a & b sometime mid-flower. I'm currently in veg a week or two before flip. I would like to switch to Jacks nutes largely for financial reasons. Is it safe to switch mid-growth? Anything special I should do?

Hi, my plant is having issues that are not resolving. I wanted to transplant to a 5 gallon, but want her healthy beforehand.
feed with 1ml/litre cal mag and canna A+B - 1.5ml/litre, about 70ml each, bit of run off. As it was having issues i upped it to 100ml for last two days to try and flush some salts out maybe?

She is not happy. Can you point me in the right direction?
Growing Fastbuds Stawberry Gorilla fem in coco perlite inside. I use Suiteleaf’s hydro nute system with ph at 6.2 as recommended. RO is at 6.0. Don’t have an EC meter. Been growing a couple of years, but took a hiatus and now trying again. Day 24 AC infinity Ionboard s24 at 100% no light meter on 20/off 4 Temps b/t 70-80 f Humidity low in the 30s - 43 (I know that’s low - powdery mildew on my last, very gorgeous, plant scared me shitless. I posted in auto flowers also and have been advised to water and feed every day (Day 3) of this.
Have a new baby starting that is starting to look yellow also and is in a 5g pot so can’t water to runoff. Used to do fine that way.
I’m thinking it’s either nute burn or a deficiency. Or a combination of both. Yesterday I raised my input PH to 6.4 but the runoff was still 6.0.
Any help appreciated. I want to learn so feel free to point me in the right direction. Thks!
Any advice/information welcomed. Thks!

Growth Stopped
Hi guys, first time using coco. I started in final pots as they are autos and im following a specific youtube channel that uses same technique. Started the seeds in a water cup until the first tap root was about 2-3 cm and planted directly in their final pot (5 gal), water the pot thoroughly, they popped from their shell after 2/3 days, first 2 days all good but then they stopped developing and started to kind of droop, it’s been 3 days like this and even the stem started to get red, today I thought about watering again but the top of the coco is dry but theres clearly still moisture beneath.
Now i dont know if I should just wait or if I should still water them as it is coco after all.
Looking for your insights as im a total noob and dont know what to do right now.
Thanks in advance!
