Olympus Up by nectar for the gods is a great way to raise your soils ph. It’s liquid lime. Calcium carbonate. Its about the only quick way to raise the soils ph with lime. Using regular lime is not hydrated and will take a few weeks to have any real noticeable effect. Powdered lime is great for soil mixes but not an additive. I’d suggest finding a local retailer that has Olympus Up and using that. Be warned though. It is potent stuff. So you don’t need much to have an effect. It’s best to raise the ph slowly over a number of days vs doing a flush and raising it all at once.
Thanks I’m ordering now! How would you suggest I use it? I’m watering with tap water. The ph is around 5.3 and ec of 115. Which thought it was 6.5 until I found out drops were off. Thanks for all your help!
Sorry for the question overload but when my meter is reading 115 ec is it actually 0.115? Also when you say add 0.3 cal mag does that mean on top of ec before adding? So total if I added to my tap water would be 0.415? I’m new to all this it’s kinda confusing!I would be tempted to flush them with a low dose nutrient solution (0.5ec) with a ph of 6.5, Then give them a Full strength feeding. Start with RO and add 0.3ec Calmag. I wouldn't normally recommend this but those plants are old, and the soil is likely depleted of Ca. Plus it looks like you have both magnesium and Iron deficiency. Bring it up to 1.5ec with a good balanced base nutrient. Ph with potassium silicate.
I would also give them a foliar of just calmag, at about 0.1-0.2ec.
If it's in Pro-mix you should be able to re-buffer the ph without too much trouble just by appropriately adjusting the input ph and an adequate flush. If it's really stubborn you could top dress the pots with 2-3 Tbsp of dolomite lime each.
If you have a loupe, make damn sure those are actually just fungus gnats. 9 times out of 10 they are. But you should positively ID them to make sure they arent root aphids which can look quite similar to the untrained eye. Root aphids would also cause signs of deficiency. If it's just fungus gnats, use lots and lots of yellow sticky traps right at the soil surface. They're a nuisance but not really that harmful to the plant.

What potassium silicate do you recommend? I’ve been reading where GH can be dangerous if mixed wrong.

I’m thinking you found my problem. Found this on one of my Cherry Moms today!!!! Found a few on other plants but not like the one in picture. I don’t really know what to do everything you read says something different. A lot say imid is the only way which idk might not be as bad for me since I don’t plan on flowering anytime soon. I’m planning to make 200-300 more moms off these moms. Might not flower these ladies till next year if I can get though these little creatures!!
Thanks for any help farm
Yeesh, those look like regular Aphids. Are you seeing them in the soil or just leaves?
Is there any white chalky looking stuff on the top of the soil?
Imid will kill Aphids, no doubt. Something else that will is Botanigard 22 wp. If you are a long way from flower I would personally use both. But that's me. Pesticides make some people squeamish. I dont mind using them if they're used properly, and as a last resort.
Not seeing any of the little green ones like on the underside of leafs in soil. I do see some little black winged bugs crawling through soil. Haven’t got them to be still enough to look at them with loupe. Just got sticky traps up this morning. Hopefully I’ll catch some so I can take a good look!! However I did see some of the little green one crawling around rim of pot. Not seeing any chalky looking stuff.
What Imid do you recommend? How much per gal. for soil? Also are you saying mix botaniguard 22 and Imid together and treat at same time?
Thanks for all your help
When you catch some of the little winged bugs on the sticky traps post a pic. That sounds like either FG or RA. FG's wings will be the same length as the body. RA will have wings twice the size of the body.
I would recommend Merit 75 at 1/2 tsp per 5 gallons of water used as a soil drench. 2 applications 10 days apart.
That will kill 99.9% of them. The botaniguard I would spray on the leaves at the same time as the Imid application. I'd also apply it as a root drench a week after the last imid soak.
These are not cheap pesticides mind you. Botanigard 22wp costs $122 in Canada. probably more like $80-90 in the US.
And dont use Botanigard ES, try to find the 22wp. It has less phytotoxicity.
