Newbie here, literally just started growing 2 weeks ago (acquired plants), purchased 4x4 tent system.
Transplanted into 5 gal two days ago. Soil and water ph around 6.1 (following the HowWeedGrow) schedule and nutrition schedule. The plants were a bit yellow when acquired them but they’ve been growing pretty good. Plants are estimated to be about 5 weeks.
Today I noticed this, thoughts?
Plant 1
Plant 2
Any feedback you can offer is much appreciated.
Your ph is a little low. Soil grown Cannabis prefers a ph of 6.5 and sometimes a little higher than that. Also, leaves will come and go as the plant progresses through its veg cycle.
They were just transplanted so I’d give em a few days to acclimate before worring about anything. If the leaves were yellow, they may not green back up at the same rate. Also, don’t water too frequently…cannabis likes a good hydration and a good dry back…
Thank you for your input. I did a soil slurry test and the ph was low when tested with 6.2ph water (happy frog with 6.2 was 5.6). I increased the ph in the water when watering but I guess undid t go high enough. In that case. If the soil was 5.6, what should I have adjusted the ph to? 7.1?
@StickyFrostyBuds is pretty much spot on,
Good soil will buffer its self nomally…
[Questions]
Your ph of ground well, city ,or R.O. water is naturally 6.1 PH?
How are you checking the PH of your water and soil? (Im sorry if this seems like a silly question)
You didn’t give much info… other environmental things also play into plant health, like RH, temps,frequency of watering,Light distance. ect…
Your plants seem really light in color… and by the fading happening from inside of the leaf, im guesting mag issue… but overall your plants look hungry… or a over watering schedule, or ph is out of wack… … my guesses anyways…
Oh damn… your soil PH is 5.6?? How?
I took 1c of the soil from the plant and 1c water, mixed and sat for 24hrs. Ph was low. My tap water is 7.5 but I adjusted it down a bit, guess too low.
I know I didn’t overwater, I let dry between and check with my finger and a moisture meter. Also, the PH meter is crap, I bought a new one yesterday and I fact the old one was off by .3
They were dry this morning and I watered them with 6.8ph (adjusted) distilled water with a pinch of epsom salt. Should I add nutrients now? Or wait till next watering?
RH has been around 60%., I found out last night that our water has chloromine 2-5ppm so sitting it out does nothing for me from what I’ve read. I ordered a filter last night as well. Lights at 450
Watch the tops…(new growth). I can see the whole plants now… looks like the tops of three have nice color… the one looks off…
7.1? Are you testing the tap water PH before or after, when you add nutrients?
Testing after. Then adjust.
I was surprised by how low the ph was a week after my last feed. The happy frog soil seems to be lower than I expected and I don’t think I adjusted high enough to offset.
Should I wait till the next watering to add nutrients of should I go ahead and do it now?
A tablespoon of 3% peroxide in 5 gallons of water will bind to chloramines and gas off within minutes. A quart of it costs $1 at Wally World.
Doing a slurry test should be done ideally with distilled or straight R/O water. You do not need to PH straight distilled as there is no ‘PH’ present. The meter you use should be a quality digital meter that has been properly calibrated and stored correctly. If you are using any kind of soil probe meter it’s a waste of money. Apera and Bluelab both make quality meters and will be the most used tools in the grow shed.
Not knowing exactly what your setup is makes it hard to determine a course of action.

Maybe up the dose abit … but if were me I’d keep doing what you’re doin and see of the rough one improves… again, watch its top…
Thanks for the feedback. Amazing, one day I never even thought about growing, the next day BAM.

Thanks to the feedback from this group and hours and hours of research, my plants seem to be much happier this week.
I fed with just water last week and just dosed my week 6 with the Flora-3. I started LST and as of this morning they loo better than they have since I got the plants.
The yellow is mostly gone now, the striping on the one plant seems to be fading and new growth doesn’t have striping. Biting a lot of new growth this morning.
This morning I watered to runoff (water only, 6.8PH)
My output PH is 6.4, ppm 79, EC 89
My ppm at 1720 - from what I read this is high?
EC - 3444 (not sure how to read this meter)
I’m not sure I watered enough for 20% runoff, Should I pull them back out and flush some more?
