PH Dropping quickly?

[Weedhound]

Mine always drops when I first add nutes too and I have to adjust up. Will be keeping an eye out for updates...

damn mr.E ,
i was always in a constant fight to keep ph from rising not dropping . i don't have the luxury of r/o water tho . no clue w/ this 1 .
peace

Yeah that was strange. Maybe it was due to some rapid growth, or heck if I know.. RO water is nice. cheaphydroponics.com sells filters now. You just need a faucet adapter (can get one anywhere, same as a waterbed hose adapter)

At the moment, I've PH Up'd to 5.8 and it's stable for now. It took a few ml to get there. My PPM is at 1400, which is the highest by far it's ever been. Maybe I've been underfeeding them. I have been very light on nutes for fear of doing harm.

These are the reasons I started with the freebie seeds and not the "good" ones.

We'll see how it goes.

odd, odd...keep us updated....keep an eye for overfert if you are jumping up numbers quick....damn numbers (actually I love them.....hydro.....right x?)

[MisterE]

Yes I am keeping a close eye.. The newest leaves are more light green and I'm afraid they're droopy. They also feel somewhat stiff. This is a sign of N overfert?
Good god this is picky stuff.
I'm going to let it go overnight at least and try to note any growth or changes carefully.

[Weedhound]

N overfert usually shows as a beautiful dark dark green in the plant which I have done personally.....the only other fert probs I had were 1. not using enough Cal Mag which caused some sort of MG def or something.....leaves were green but veins were yellow....stopped right away when I went to 50% Cal Mag with my nutes as suggested by my hydro guy (he told me to use 50 and 50 Cal Mag and nutes until I got to the top of the Cal Mag scale which I really havent' done yet...I use that all the way through flower) and when I went too low on the nutes...caused an iron def or something....the whole plant wilted down in about 24 hrs but came back w/higher nute level. None of these sound like your problem however.

keep us in the know....

Wow...My 3-part buffers right to 5.8-5.9 with ro water...Did you mess witht the calibiration on your pen? Using 3-part and calmag with rowater...You shouldn't have any problems like that, and NO...the temps don't affect ph, as far as I know.
I'll look in later. yellow is usually too low salts, but if you are following my recipe, then there is no way you are nute deficient or toxic...I can promise you that!

[MisterE]

Hi latewood. No I calibrated it just before this res change in fact. I'm extremely careful with that and it was perfect 4.0 and 7.0 when I was done. Plus the plain RO water was dead on 6.0 all night until morning when I nuted.

Could the fact that I used rapid rooters directly in the hydroton make any difference? I never added any water to them from the get go, as they lived up to their name. I've not noticed any material in the res either.

I make a point to shake the bottles well before adding the nutes also, and I add them micro, gro, bloom in that order directly to the res and stir each before the other (plus my water pump in the res stirs constantly and streams into the grow tub).

Since the change and adding the ph up, it's been pretty steady at 5.8. I havent had to readjust it at all.

The plants looked better (and smelled more) this morning. Last night 5 minutes before lights out, I very lightly misted the tops with straight RO water.

What about the old empty milk gallon jugs I use to store water? I rinse them and wash the hell out of them and rinse several more times and let air dry before using them for RO water. Is that a huge issue? I've never seen it mentioned, but trying to cover everything. My filter is close enough to the res where I could actually fill it directly that way, but it'd take several hours.

These issues all started before I started using your formula, so I'm sure it's nothing to do with that. The branch growth is great on these things, especially since they're so squat. Odd though that the shop I got the seeds says this strain likes to grow super tall. I think most of these things have to do with my inexperience with hydro, and starting them with my hard as nails tap water.

Help.. Im having problems with my ph dropping while in the trays. The reservoir is at 5.8 and when I measure in the tray durring watering it reads 3.6 also have yellowing leaves and stunted growth. Doing ebb flow and RO water, water temp 78 degrees. Tray just cleaned 2 weeks ago.
