So, no nutes on any of them this round, correct?

Keep monitoring your run off numbers with the water feed only. Start feeding nutrients once the PPMs get down to around 800 and feed at 800-1000. Cannabis grown in soil benefits from a drench to drought routine and with synthetic fertilizer liberal run is recommended. Checking run off each time gets less routine with a few grows under your belt… you’ll get accustomed to reading the plants health from her leaves. Best advice I can give is keep it simple and less is best :love_you_gesture:

Ok, just watered at 6.8 (2 gal each (5 gal pot)

Plant 1 - EC 3102 / PH 6.1 / ppm 1504
Plant 2 - EC 2020 / PH 6.6 / ppm 1004
plant 3 - EC 2326 / PH 6.4 / ppm 1170
Plant 4 - EC 2888 / PH 6.4 / ppm 1446

Plant 1 still low, watering to drought which is about 3-4 days between

@OGIncognito nailed it on his recommendation. Get your pH up and keep monitoring until you reach 1,000 ppms. You’re getting close.

Is there anything specific I can do for the low one? Flush with a higher ph? Or is that bad?

Yes that’s what @OGIncognito was telling you. Go in with 6.8 pH’ed water to help assist raising it to your 6.5 range. Run a couple few gallons through and keep watching your pH till it hits 6.5

Keep watering this plant at 6.8, but let the medium dry between watering. The 6.1 isn’t so low that a reset flush is needed. Most organically amended soils will buffer this within the range. Give it some time to adjust to the higher 6.8 :love_you_gesture:

Day 6 of my first flower. So far I’ve only added nutrients 1 time due to a calcium deficiency around week 4, only water since. Happy Frog Soil. Based on my last watering they may be ready for nutrients after another couple waterings.

Here’s my latest numbers of today’s watering.

Plant 1 - EC 2862 / PH 6.2 / ppm 1428
Plant 2 - EC 2406 / PH 6.4 / ppm 1203
plant 3 - EC 1638 / PH 6.4 / ppm 820
Plant 4 - EC 1676 / PH 6.5 / ppm 839

So, the PH did increase 0.1 in plant 1 headed in the right direction.

Plant 1 & 2 ppm still high, too high to nute

Plant 3 & 4 - ppm is now ok to nute?

Next watering all plants at PH 6.8

Plant 1 & 2 - no nutrients

Plant 3 & 4 - add nutrients at 1/4 dose

It seems like plant number one is giving you a slight fit raising the pH. I believe getting more runoff on plant one that’s pH to 6.8 should meet your middle at 6.5 I would increase the water amount that you’re using if you’re using one and a half gallons I would use three and a half.

Your spot on about not watering with feed on plant number one and two and quarter strength on plant three and four. You’re getting there brother and you’re doing a good job. You got this

By the way what is the ppms of the water you’re giving her? Are you giving her tap water or some other type of water?

@Lostgirl ppm of my water is 82, it’s filtered tap water with a catalytic carbon filter. I added that at the beginning because our municipality uses chloramines.

Plant 1 has been a bit weird since I got the clone at 4 weeks. I struggled early on with a calMag deficiency, it had variegated leaves and I was told to add calMag. It helped. But it’s always been weird. It’s special. Guess bad genetics?

This is what it looked like 8 weeks ago. It’s a Holly Punch

I personally think you should add about 175ppm per gallon worth of CalMag to your next watering on this particular girl. Bringing your total feed over 200 PPM then pH it to 6.8

This will give your pH a little something to stick to. And the fact that your filtered water probably has little to no calcium magnesium in it it’s never going to hurt to give a low dose like that…

Here’s my latest numbers after watering per hour advice.

Plant 1 - EC 1630 / PH 6.3 / ppm 785 (3.5 gal)
Plant 2 - EC 1862 / PH 6.6 / ppm 913
plant 3 - EC 2020 / PH 6.5 / ppm 1010
Plant 4 - EC 1822 / PH 6.5 / ppm 911

Thoughts on next watering?

Plant one increased 0.1 again from 6.2 to 6.3.
