More plant problems. The upper leaves show yellowing on the tips. The bottom leaves are yellow and some of the leaves have some tanish spots in them. I just finished the 1st week of half strength of the Big Grow Fox Farm (1 tsp). Dont want to give them nute burn, so what seems to be the issue with this one?
Finishing in a 2 gallon pot can get tricky. They tend to get quite rootbound. Any way to put the drainage rocks in the drip tray and use the extra space in the pot for soil...? ( hint, hint ;))
The plants will take a week or so to get used to the nutrients. Likely the yellowing is the plant using the mobile nutrients in the leaf. Have you added anything else to their schedule? Anyway...I'd keep on schedule, and keep an eye on 'em. Holler if it get's worse. :thumbsup:
In that space I think I'd let 'em grow without LST'ing, as I'm positive they'll fill-up the space. A single plant LST'd in there might work, two would likely be overkill...more would be...unnecessary.
Regarding pot stacking...it screws-up the plant height and is a big pain in the butt. I'm pretty sure I did a thread on pot stacking. You might want to do a search and have a look...
Mmkay. No, I havent added anything. The only other supplement I have is Cal Mag or a similar product (I think its called Magi Cal). Scrapping the LST idea, as height really shouldnt be an issue in my case. I was only going to do it for the benefit of a higher yield. Better let them alone rather than risk snapping a stem or something.
As far as the yellowing bottom leaves. My main concern was the beige spotting and burn lookin tips. Ill watch em over the next few days.
Finally, what was your suggestion as far as drainage rocks? I havent been using any. I just filled the pot with Ocean Forest. Was this a mistake? Thanks for your continued tips. Im tempted to make this a grow log, because your one of the few knowledgable people to frequent this board, but I dont want to jinx the grow. Ha
Another thing I noticed, is the new leaves have been growing in kinda of curled (not canoeing, but slanting I guess) and skinny. They fill in eventually but I dont remember them doing that prior.
Just noticed you had the ingoing water at 6.0 ph. Too low. Between 6.3 and 6.8 ph is acceptable in a peat-based medium. (your 'potting soil')
Nutrients will bring-down the ph further, but once the water is tinted, you can't get a proper ph reading with the aquarium test kit. Likely best to get the water to a 6.8 ph or so, before adding nutrients.
If you want to know the ph after adding nutrients or if you want to check runoff ph, you'll want to save for an accurate ph meter. Not a soil probe, but a ph pen or meter.
Flush with properly ph'd water. For seed germination and very early seedlings, (first week or so) the lower ph is acceptable. Now she's telling us it has become unacceptable and she wants her ph raised, or she'll shut-down and lock out the nutrients. (and she means it, too :thumbsup:)
I appreciate the compliment, but am not the only source of info here. Matter of fact, I still learn stuff from you guys every day...
Most folks add drainage rocks to their pots, so the rootball won't sit in standing water when overwatered. I put my rocks in the drip tray instead. Adds more space for potting mix adding to the available rootspace. Plus, no need to pick-out rocks from the rootballs when transplanting.
My pH hasnt been 6.0 since you originally corrected me two weeks ago. But as far as pH, it could be incorrect because of the drops.
I woke up this morning and my best plant now looks like my worst. More yellowing on the lower leaves, more spotting. Ill post pictures shortly, but Im afraid to take any action, as now I have no idea whether it is too much nutes or not enough.
Main question:
The others seem to be doing fine; certain that this is a pH problem and not a nutrient problem? I think my regular water is at 6.8 and my nutrient water is around 6.3. But like you said, Im unsure how accurate that is with the drops.
Just flushed the plant. But it actually had that droop to it before I gave it the water this morning.
Also, you cant tell by the picture. But the petioles towards the top have a slight yellowish part where the fan leaves all meet
<sigh> Local connection problems...keep getting booted and spotty connections.
Still might be a ph issue, my CalMag was rediculously acidic, likely yours is in the same ballpark. But I stopped using it quite a while ago, and am unsure of actual ph. Something in the low 4's, I believe...
If using the MagiCal solely for replenishing R/O effects, a little dab will do ya. They'll need the full-strength product a couple weeks into flower per directions, but trace ammounts are all they need for now. Perhaps 1/4 dose, once a week. I prefer unsulphered molasses, but you've already got the other.
We can rule out rootbound since you recently transplanted.
But about the drainage thing...
Are you letting them sit in standing water with no drainage to prevent soil issues like nutrient lockout, mold, root rot and other assorted trumatic problems? Big bad no-no.
Might want to raise the pots, add some aquarium rocks or similar to the drip tray, and replace the pots. I use cut-up plastic milk crates. I cut 'em into 5" squares to fit in the bottom of the tray. Anything waterproof and mold resistant works if it keeps the roots out of the water. If the pan fills enough to reach the bottom of the pots, bad things happen to the soil...so empty the pan.
They look water stressed, so let 'em dry pretty good before the next feeding or watering, whichever is next. Possibly from the feeding, but I couldn't finish uploading your pix of the pots in the pan. Took forever downloading, but crashed before I could see the pan. Is there a puddle of water in the pan? (looking into your habits, lol) You keeping a fan on 'em at all times?
Use care if those are terra cotta pots. (lemme guess...plastic?)
Just in case...With terra cotta pots, it's tough to control moisture loss, and tiny roots love to grab ahold of the pores, and can be problematic for transplanting. Just use care, and one firm whack.
You're in FF soil, right? And just transplanted? Kinda jumping the gun with nutrients. Give 'em a couple/few more weeks, they'll suck it up. Resume with 1/2 dose of the Grow Big and 1/2 dose of the Big Bloom (if you've got it) after they use-up the soil nutes.
Gonna post now before I have to do this again...
<whew> Third time I've tried to answer. Was going to give-up for the day. Sure wish we had cable here in the boonies...
Ah! That sucks about the internet connection issues. I know what thats like. Actually, the two plants in the terra cotta were rootbound. I thought that those terra cotta pots were larger but I upgraded them to the 1 gallon plastic pots like the others are in. The terra cotta planters were actually ceramic (a pain in the ass to get the plant out of there!). The gallon pots were about double the size of the terra cotta ones. So they'll fine fine in there for another week or so before I transplant them all to the 2 gallon.
I havent used any of the Magical this grow yet. As far as drainage, I have holes in the bottom and have aluminum pans underneath. I dry the water up after I water them. But your idea is for me to put rocks in the aluminum pans correct? Edit: I acutally have the plants in two pots because I was concerned about the large drainage holes. To clarify, I didnt double pot. Just stacked two pots, one empty underneath the regular one. This allows the soil to always be about an inch about the drip trays anyway. Does that sound like an adequate way to keep them dry?
My feeding week starts tomorrow, and I will be feeding them 2 tsp per gallon of the grow big (which is 2/3 strength). Then the following week I will go full strength, then the week after I will want to start flowering I believe. Unless from the looks of my plants, I need to alter the schedule.
