1st Grow - Northern Light - Journal (aka help me not screw up)

[Mr.furley]

Personally I would move the light up a touch to start, you are on the bottom end of the recommend number and new growth tips burn can be from light burn. To flower your plants are going to double or triple, you have room for that yes?

[KenneyHo]

Lights are between 27-29” above canopy. Recommended 28-36”. I’ve taken some fan leaves off but don’t see anything.

[Mr.furley]

Sorry reading back for some info, have you pulled a leaf or two off the plant and flipped it over on a table to inspect for bugs? holes are usually a Telltale sign.
Looks like you put your plants in 3gal a month ago, so yes they may like a bigger pot. I'm just thinking that in the bags you roots should be "Air pruning" and shouldn't be root bound. How far is your lights?

[KenneyHo]

The holes were already showing up, as were the tips before flushing. The small growths dying off was after the flush.

[Mr.furley]

Did you leaf start changing after your flush?

[KenneyHo]

Yes, In the previous post I mentioned the sulfur like smell that lasted for a couple hours after flushing a couple days ago. The tips I think are from increasing the nutes from 1/4 to 1/2. More worried about the smell.

[Mr.furley]

KenneyHo
Your new growth tips are discolored which can be from
1) to much light
2) to much nutrient
3) a combination of 1 and 2 together
And yes root, watering practices and/or bug problems.
Have you flushed lately?

[KenneyHo]

Bump for the Saturday crowd. Any thoughts on the symptoms described in my last two posts?

Thanks again for any help!

[KenneyHo]

A few more pics of other symptoms. Smallish holes showing up on some leaves and some under canopy growth dying off. No sign of pests that I can tell, however I may be missing something. I know that if there are root issues, then it can show up in a number of ways on leaves.

Temps: 71-81f Lo/Hi - 77 avg
RH: 51-61% Lo/Hi - 55% avg
Nutes: 1/2 Strength FF Trio per their schedule, CalMag
Water PH: 6.5

Ok, so I was planning on switching to flower today but have run into something that is making me reconsider. I gave all 4 girls a good flushing yesterday with the anticipation to switch to flower today or tomorrow. After the flushing I noticed a sulfur like foul smell coming from the girls when I put them back in the tent. I’ve read a few opinions from root rot to salt build up. The smell lasted a couple hours. Runoff PH was 6.5. The girls are still green and look healthy but one (Top Left) is having some tacoing and it isn’t heat stress. They are currently in 3 gal fabric pots and I’m considering transplanting into 5 gal to see if fixed the potential issues before flipping to flower.

I would love any and all thoughts or suggestions. Thanks!

Pre-feeding pics from tonight. Day 46-39 (oldest to youngest). The 3 biggest have been topped. I’ve not done any training on the runt due to her having some challenges early on, and am just letting her do her thang at this point. Probably switching to flower within the next couple weeks.

Continue to remove fan leaves that block light from maki g it through the middle of each plant. These pictures are pre-feeding tonight.

[KenneyHo]

Yes it is! I picked up one off Amazon with a Rh % setting, which has helped greatly with keeping the rh consistent.

Hey kennyho is that a humidifier in your tent? I’m having humidity problems that’s why I ask

[KenneyHo]

I removed a few more fan leaves from the biggest two, giving better light for the potential shoots underneath.
