Help: Rising problem @ NL#5xHaze

Hello,

What is your experience level?
Novice

Your Equipment:
Outside in pots (not much Sun these past 3 to 4 weeks. Temps day: 18º night: 8º/9º (8 days ago moved the plant indoors to my house)

Your medium:
.7) BioBizz Allmix
.8) 30L clay pot
.9) Did you use peat pucks (or similar) to root clones or germinate seedlings?
Yes, coco and then transplanted right into current pot.

Your nutrients and water:
10) Source of water?
Bottled 5.8 +/- 0.1

11) Method of checking water ph.
Aquarium test kit

12) Method of adjusting water ph.
- PH Down

13) Specific brand and N-P-K ratio for each bottle. List dosages (quantity per gallon) and current feeding schedule.

- FertiActyl GZ: 4ml/l (NPK 13-0-5) Nitrogen in Ureic form (slow release) - I'm testing this Timac Agro. Dosage is still tricky: recommended on bottle is 5L/ha. Also is recommended to feed once every 2 weeks. I was using BioBizz FishMix before 2ml/h (once a week)
- Biobizz BioBloom: 1ml/l (NPK 2-6-3,5)

At the moment once a week feed, except FertiActyl GZ once every 2 weeks

14) How often are you watering between feedings, and how much per watering?
I'm going to start 1 Watering between feeds middle of week.

15) Any additives or tea's?
- FertiActyl GZ has fulvic and humic acids with easy absorbance (used to use Enzimes+ for that purpose)
- Biobizz Alg-a-mic: 2ml/l
- Biobizz bioHeaven: 2ml/l
- Piranha: 1g/l
- ATA organics Flavor 0,5ml/l (NPK 0-0-9)

16) Are your ph levels stable, or do they fluctuate?
Fairly stable (soil meter reads 7 all the time, but I don't trust it).

17) What is your ingoing water's ph? ...your runoff ph?
Between 6.0 or 6.5
Runoff is same

18) Do you foliar feed? If so, with what, how often, and at what time do you spray?
no

Your growroom:
19) Indoors or outdoors?
Outdoors

20) What size of closet, room or hut?
backyard

21) What are the temps and humidity levels while lights are on? ...With lights off?
no measure

22) Have you seen signs of insects in the growroom?
there are white flys on other grows I have: mint, oreganos, salsa, etc. Also have them on MJ plant (using neem currently: no good. need something stronger, any suggestions?)

Your strain:
23) What strain are you growing? (Indica dominate or Sativa dom?)
Northern Lights #5 x Haze - Sativa Hybrid

24) From seeds or clones?
Seed

25) Is this an autoflower strain?
No



Hello all,

She has aprox. 30 days old from sprout. Up untill 4 weeks I was feeding with FishMix for veg grow using the dosages recomended by BioBizz feeding charts. April was a bad decision for sprouting: Lots of rain, no Sun. Even if they're fairly protected from rain, can't do anything about the sun. At around 25th talked to friend at Timac Agro to suggest me one of his star brand products: FertiActyl GZ. Went to store (agriculture coop), bought it and used it on feeding at day 27th (last friday).

Before that on day 26th I pinched main stem and started to LST.

Dosage instructions on FertiActyl GZ are on l/ha, so I did a direct convertion to ml/l. That might not be the most correct, but I don't know better. Recomended dose is 5l/ha, I did 4ml/l. I think I might have overdone it. Symptoms started to apear:

on the 30th - monday:
- green/brownish discolor tips at 1st leafs (they weren't yellow burns so I excluded nute burn, maybe incorrectly).
- noticed the stem had red markings (maybe from before LST)

Attachment 284292

On the 1st May:
- same green/brownish discolor tips at 2nd node
- blade at 1st node also started to show same thing

Attachment 284293

At day 2nd May:
- did a mild feeding with BioBloom because I thought about P deficiency (people advised me it was P deficiency due to NPK of 13-0-5.)


Currently on day 4th May:
- same thing at tips of all fingers of leafs at 3rd node
- all other tips below are afected
- at 1st node one of the oldest leaf fairly affected at the blade shriveled and I removed it (also some green discoloring to a pale green)

Attachment 284298 Attachment 284295

I ignored the tip burning as nute burn because of colour. Now not so more. Since N is present in ureic form and will have a slow realease (FertiActyl is supposed to last for 2 weeks between every feed) I'm thinking it might be that. Not sure.

I don't know how to flush if that's what I'm supposed to do. How many Liters should I use for 30l pot? Is tap water with hose (ph7.8 to 8.5) directly on pot ok? Should I restablish some micro or macro nutes after flush and how to do it?

If it's something else please consider I'm a noob and need to be teached.



Thank you very much in advance!
H.

There's also some malformation at 2nd newest node.

looks pretty much like you're doing everything wrong here. I'm guessing allmix has fert to it and if so it's probably enough to last for a while, meaning you don't need to add anything. why are you pH your water to 5.8, if I read that right? that is the lower pH number for a hydro grow, not potting soil, and yes there's a difference. I didn't believe it either but seems to be true, hydro water lowest pH at 5.8. For soil go buy distilled water and give that without changing it. 6.5 pH should be fine but just distilled is best. Don't put together a bunch of fert but then back them off by only giving half dose. If you don't know if that much fert is good, then don't give any. Let the soil maker tell you what's needed and what's not. Solve your grow problem with using powder fert, like foxfarm's fruit and flower, one half cup fert per gallon, 4 liters, of potting soil. give no additives unless you know you have to. don't believe all the junk you get told cuz most of it's wrong.
