@Creativebuzz, Thanks Creativebuzz. :blush:

Good looking buds. Enjoy

Nice looking bush, going to make for some nice flowers ;)

Sorry Jung pot, But what are you feeding them presently any ways. I recommend using recommended amounts from company. I use plagron coco a b and green sensation and cal/mag which amounts to approx 10 ml per liter. You only want water in the flush, rest of the time use the nuts. Your not servicing the plant if you go easy on the nutrients. They need it.

I have this strain in it's high THC form look forward to seeing how this turns out!

@Stick, Thx Stick

@jungpot, can you still use the ph down mixed with the nutrients? That would be the way to go i think. If you have the tester and the ph down you should use it. I would just be more interested in using nutrients every watering. And try to maximize watering with out causing over watering. You still on a winner for this grow i think it looks great, very tidy. If you allow more foliage and stems in next grow you'll get a better yield. I was wondering about the size of your pots considering if they are smaller you can water/ fertilize more often. I am using 90 % coco and find it great really, just had to switch over to coco nutrients along the way and realize the ph can be an issue as well which i need to remedy for the future plus mag uptake is one to watch in coco, but alas I'm running a chaotic system and it is not too bad as nugs are good. Also running autos so they are maybe more forgiving. Goodluck with it

@DirtBox, i used like 20 % of coco and added 10 % of peat. have 19l pots, but i think next time will not use coco at all .i followed your advice and feed 1 liter on 2 days. so if i understand correctly you wouldn't use ph down water at all on every other watering?

@jungpot, I would Not Ever double nutrients. But maybe they can take it but it is never a good idea to simply double. You prob will get nut burn, which is not so bad but then you might need to flush them and it may be simply unnecessary and stressful. My advice is instead of feeding 1.5 l every 4 days, feed 1 liter every 2 days, keeping the recommended ratios. Then your almost doubling your feeding but not shocking the plants. They could even take 1.5 every 2 days. See what the soil can hold anyways, as in pour the mix in parts and see when it comes out the bottom. You could even try this one one plant for a week and see how it deals with the extra watering and nuts. Liquid food is available all the time for the plants and when you water air is sucked into the soil so it is a winwin imo. Your basically running hydro but using soil/coco as a medium. The plants only eat water soluble nutrients. When you leave the soil dry there is no food at that stage leading to possible mag deficiency and nitrogen deficiency. Just my 2 cents, I've tried different schedules and now will feed every 2 days and every day if i find a hungry plant, as in pot getting light quickly. Sometimes I'll just add a little to all of them. They don't show any signs of over watering or nut burn so I like to fed them this way never leave them wanting. What percentage coco are you using anyways and what size pots. I'm using 12-15 liter so pretty small and suits regular watering/feeding.

Search ggoogle images for 'Cannabis nutrient deficiency excess' and that chart will explain all about deficiencies and excess nutrients. That's a well tidy grow you got, well done. You could have kept a few central bud sites, possibly too much pruning, just my opinion. Wanna get as much as possible don't we. I always water my plants every 2 days and even daily. Better to feed those babies as much as possible imo. If anything I'd say the yellowing is from lack of food. Increasing water times will provide them with more food. Just keep the recommended nut ratios. Opinions vary but i don't see why you'd always leave the soil totally dry out before watering. I heard but no proof that drying out soil containing coco can change the ph. Now I'm not so scientific in my approach and don't gauge anything presently, so if your irritated by my observations don't worry. lol

Watered with ph down on 6 . soil is dried now on 4-5 days. on every girl went 1,5 L of water. lowered humidity on 50 %. Tomorrow i will change exhaust fan with PK 125. finally :)) at the moment i have TT125 for exaust :(. i was waiting to spare some money :) so hopefully i will correct temperature and humidity with better negative pressure .

Hey Stick Appreciate for reply and helping me. i posted new photos today with better resolution. hope it helps to identify the problem. i think its ph lockout.

Hello @jungpot! You're doing great with this scrog session! Well it's hard to say with the last pictures you provided, could you try to post a zoomed picture showing the yellowing? If you see burnt tips on leaves, curling-upward leaves, brows spots, or yellowing between the veins, then it's an excess of nutrients. If you're seeing fading-leaves, loosing their bright green and slowly turning to yellow, then it's a lack of nutrients. From what I see in the pictures, I'd go for a deficiency. In such case, we'll need better pictures to tell you what nutrient is involved. Hope this helps, keep up the great work, I'm really looking forward to your progression since this will be my next strain, keep us up-to-date and happy growing! :facepunch:

Today is 22 day of flower. two days ago i watered with weak solution on 6 ph. Next time will have to practice more in time of transition. i didn't do well on covering whole scrog net. think now is to late. Have problem with yellowing again, i think from the start i choose bad soil with high ph

@Stick,HeyStick .thx for advice . i left little space between tie and stems.

@jungpot, Ties need to be adjustable, you don't want too tight or it will cut your stems and hurt your babies, otherwise it's looking good! :clap:

Girls are thirsty more and more. i hoped previous watering will last 5 to 6days. So today i must water them with solution , next week i post quantity mix . Humidity dropped down , still little high ( 60%). Want to get it on 55%, but problem is outside air. i am using a lot of ties, bought new package :)) really trying to put her horizontally . in few hours before light turn on i will post new photos.
