Not lately. Still havent figured out why i am locking out phosphorous and calcium or mag around week 4.

Climbs right up the fan leaves. Typical cold roots or overwatering but neither should be a problem at this point.

Im going for new soil this afternoon but if it was the soil i would see deficiencies in veg at some point I would think.

Like they say. Happens to all of us. I am frustrated and want to know what I am doing wrong.

That really looks like root to me. Bugs, temps or damage. I don't get that over watered feeling it's just not uniform enough over the whole plant. It's not bad just off a bit I would kinda lean to temps. Stuff a thermometer in there maybe? Or check the temp on the bottom with an IR temp gun?

Just thinking out loud brother

I always add some extra lime to my Ocean Forrest along with added perlite. Have for the last 5 years.

i answer that,they will keep growing and filling the pot,then you will have a monster of a plant,when i did it in 5 gal bucket,plants got 7ft tall and i was scrambling to keep out of my exhaust fans and lights,with a ton of bending and tieing i did have a great harvest though

Yes , but you can grow large plants in 3 gallons also.

5 gallons I have to top and train into bushes.

im thinking enzymes in some already great soil be a good addition,i grind steel oats and barley top scratch it,then ever feed add a little coconut water to help compaction,all 3 lead to uh humm good

it can but when you dont wont um tall not such a good thing hahahahah,i had a 7x7x7 old bath room needing remoldled that damn thing was so over grown i had to crawl in the bitch nija style just to water and tie there ass down,no shit had a little path threw the middle and when i harvest all i did was start cutting strings from the ceiling ,they all fell over and took one bucket at a time out,as i did cut crap load of string from buds and buckets hahahah

Im not saying it IS root zone temps but @MIMedGrower sorry for using your thread to say this.

One of you soil growers need to pick up the ball on root zone temps.

I have found first hand a significant difference in vigor with root zone temps of 71-74f over the 65-68f in hydro. We know cold root zone at a point slows growth and we start seeing deficiencies. What soil growers are not optimizing is how do you get the most out of root temps. Now I mean this withing reason its not practical to put heat mats under every plant but there has to be an economic way somehow to test this. Maybe like the heated flooring to heat rooms with radiant heat instead of heating air?

Know that feeling.

Also I still have some gnats. But only a couple flyers here and there. Using Microbe Lift again after a few week break.

Aaaarrgggggggg!

Have you closely inspected those fliers to make sure they arent winged RA's? They look almost identical with slight differences. It would account for the phantom deficiencies. Maybe just something to look into.

Beachwalker said:

What was the reading from your slurry test?

Click to expand...

Dont do slurry tests. Just runoff.

After mixing fresh soil it read 1.4ec

After the problem starts i have readings from 1.8 to 2.8.

One plant with 2.0 ec was fed .8 ec.

All typical signs of overwatering but i swear I am not.

I must have early fed every plant. But i didn't.

Frustrating.

When I did that before my ph kept rising. I figure its because i use well water. Dont need more calcium.

In fact too much calcium can cause my problem?

My floor space around the pots was in the low 60’s when i checked last week. I usually keep it above 66 farenheight. It is closer to 70 now that i have adjusted things for a week.

I have seen this problem start in ocean forest before. But an extra gallon of water before a light feed has aleays stopped it at the bottom. I have never had it progress this far so fast or often.

And i agree. Its a root problem. Maybe too much calcium, iron or cold and wet and locking out phosphorous.

I waited an extra day to water on a few plants and one wilted so i am still stumped.

I will definitely re inspect some roots. I have been thinking this for a while. But have not found evidence.

I will pull a plant up some and use my scope again.

These where grown with 400 ppm well water with 280 ppm of that as CaCo3. I still have pots so caked up with the calcium carbonate I don't use anymore.
Also grown in a old pole barn with little regards to the environment.

So what do you suggest? I really have not changed anything. Even when the gnats were at their worst i was getting my best yields ever.

It's a good idea to check anyways. Your issue just reminds me of my problems a few grows back. When you're doing things the same as always and have these sudden unexplained deficiencies it's honestly the first thing I want to rule out now. Look for chalky white residue on the soil and after you water inspect the base of the stem with a loupe, you'll sometimes catch them climbing to get out of the water. And the fliers will have wings that are longer than the body. About the only noticeable difference between them and gnats.

I hope it's not the issue, those fukers are ruthless and they scare me now. It's always good to monitor for them when you get unexplained feeding issues.

I don't believe the calcium in the water will effect the plants, molecules are too large from what I've read. Other than raise the PPM's.

agree I started using dunks and bits when I got thrips and I am seeing very few of anything anymore on my yellow stickies

Also I started heating my roots with reptile heaters and watering cycles & growth came back to normal

I've done maybe 2 slurry test this whole year but I would do one now if it were my plant, good luck hope you work it out!

You or someone mentioned something about old pots being caked with lime (can't find it now). You can soak pots in LimeAway in a bucket, rinse well and dry in the sun. Rinse again before use. I wouldn't use it on porous materials like clay but for plastic it works like a charm.
