Greenpoint seeds!!

Big Green Thumb said:

Maybe you guys can help me out with this OBS #3. This plant has these spots forming on lower leaves (my CC had this too). I added 3 ml of calmag per gallon to try to combat this when it happened on my CC and maybe (?) it helped. This OBS started it while in veg and it isn't getting any better. This plant is growing in 100% perlite, getting Jacks 3-2-1 (3.6 grams-2.4 grams-1.2 grams) and 3 ml/gallon of calmag. Ph'd to 5.8-6.2, fed nutrients every watering. Please help!

Could just need a good flushing. What ec do you run your nutrients at?
Are there any other symptoms other than a few dead spots?

There are a lot of factors to consider, or ignore, for sure. The base nutes I use, from the folks who make Jack’s, is called “Oasis Hydro FeED 16-4-17,” which are the NPK numbers, says on the bag it is effective to pH 8.0. I know iron dtpa can be absorbed up to pH 7.0. I ran coco between 6.5 and 7.0 for years. I run DWC hydro between 6.0 and 7.0, anywhere in there is fine. One thing you learn in the aquarium hobby pretty fast is pH is not likely to be your problem unless it is way out of range, and that some amount pH swing is a good thing. I brought those assumptions with me to this game and haven’t seen any apparent ill effects. Most of us sweat the pH thing way too much, in my opinion.

I will briefly elaborate on my homemade system so everyone knows I am bananas, instead of having to guess.

I add a bunch of calcium nitrate and some iron dtpa to make the Part A stock solution, then make Part B out of MKP and MgSO4, I run them at 200-156-244 npk from cradle to grave. If anyone wants to try it I will send you my recipe, it seems to work. The clones in the pic have been run at 12/12 since before they really even rooted, 0 veg time. I start at EC 1.2 and pretty quickly ramp it up to as high as EC 2.4 then let it ride. I did a fair bit of math to come up with the system, now it is totally fire and forget. It currently costs me a touch under $0.12 a gallon at full strength

@quiescent I saw you mentioned Blumats being a big benefit to your growing, I totally agree. They can make soil feel like hydro, in terms of growth rate. I moved away from them right now, but in coco and soil they are great. I tried them in rockwool too, but I made some mistakes, might try it again someday. As long as one cleans the damn dripper tubes every thirty days they are pretty reliable. No system is without maintenance.

I thought I saw feminized seeds on the site listed, but I could never find any. Are these out of stock for good or have they ever had just fem? I am in a state where I can really only have 1 or 2 at a time an don't want to waste time waiting for sex, but the genetics look sooo darn good. Thanks for any replies maybe I'm too baked an there were never feminized

Great point. 1 tsp epsom is already over 1.2 ec with my tap water.
The fellow should check his. Most have a tendency to add more shit when they see a problem.

Less can be more.
I prefer an ec of 1.1 in a drain to waste, using coco. I always use Cal/Mag, especially important in coco.
It is cheap insurance against low yields.

I still get nute burn if I dont flush the salts once a week.

Day 60 prob got another ten maybe

Chopped JP and Bliz bush day 70

Almost bought some GPS gear this morning. After the third fucking popup got in my way, on the first page I clicked, I totally lost interest, and now I am merely annoyed.

One of my Jelly pie's at 5 weeks since flip. I just cant get a good picture of it but she looks like she has a fur coat on since week 3.

Nutes are at 1070 ppm. The spots historically get worse, affected leaves yellow, get crispy and die.

Prior to this grow I was using blumats in coco/perlite. They did very well for me. The only issues I had were the lines clogging occasionally ( or sometimes flooding) and all the damned yellow mushrooms that grew. I would put alcohol on the shrooms daily and they would wither and die. The next day more would be popping up. They say the shrooms aren't bad for cannabis, but I didn't like the thought of their spores blowing everywhere.

Why not a mix of boards and cmh?

Thats been rolling around in my head too. I'm thinking about making a couple bars with the QB 96's to even out the coverage if I go with the cmh's

What conversion rate does your pin use to figure the ppm from the ec? Different pens use different conversion rates.

Here's a good read on the subject from a great site for hydro geeks.
https://manicbotanix.com/ec-to-ppm-conversion-chart-2/

I run drain to waste and plants always have fresh nutrient to absorb. There is no need to run higher nutrient levels to compensate for those that the plant uses like most do using a recirculating system.
If your using blumats or hand watering, you should use far less than your nute manufacturer recommends and make sure to flush those roots.

Those shrooms are epic, I would almost pay money to get them back.

The lines clogging and flooding sucks, I have found in my case if I shut off the supply valves pull the dripper tubes out of the carrots and squeeze the gunk out, then rinse the salts off the tip every 30-40 days I don’t get floods any more.

My ppm pen reads the .5 or 500 ppm scale, which means I am in the 2.1 ec range.

Why would you want the shrooms back? They always worried me that they would poison the whole grow with spores stuck in the buds, in my eyes, mouth, etc. LOL

I'm not sure what system of hydro you use, but my plants would be hurting at that level of nutrient. Mine would be 500 to 600ppm at that range. I feed a minimum of 3 times daily.
I use a 5-10-9 NPK with 5ml of Cal/Mag per gallon, from veg to bloom and I still get nute burn at times, especially growing those Chems.
The buds get large though.
Here's some Jelly Pie.

Drip clean by house and garden will fix your problem.

I have had them in lizard frog and snake terraria for years, I think they are cool and I am not dead yet, if they were significantly toxic I would probably know by now.

Having said that, I don’t think I have them as bad as you I would have one or two of them per plant per grow, and that was it. If I had dozens of them popping up in the tent I would probably worry

So will switching to DWC! Which I have now, except for my mothers, which are hand watered in soil. Thanks for the tip! I am going to buy some, planning to grow veggies wih the Blumats this spring.
