Yeah he is now a place holder… On the plus side crown rot is improving immensely so im confident from here on out the growth should get better as well.Looks like PUFF has it all under control.
how much ppm mg?Ok so we are still sitting at the following conditions. Im taking some stress tests tgis grow since its not been ideal from the start and i am curious to see what if any (for you ppl who watched the depp trial) effects o2 may have on them
50% RH
80f temp
(i probably should running a bit higher RH)
res temps still at 83f
co2 1000ppm
900ppfd.
increased mag sulfphate a bit but going to bump up more again in a day or 2.
800ppm
PH 5.8
that i cant say for sure all i know is they needed more. Im using jacks and adding about 1.5 grams per gal of mag sulphate currently and got a gut feeling i may need a touch more but want to wait a fee days to see the full response. At 1 gram per gal it wasn’t enough for my conditions… but my conditions are also not typical and that could be contributinghow much ppm mg?
Yup yupthat i cant say for sure all i know is they needed more.

yeah id say 2g per gal is still plenty safe. i dont think you had to much as that looks like where im headed alsoYup yup
I was using around 1.5-2g of epsom at some point
Probably a little much then but still
Curious...at the point that you are at in veg obviously nitrogen is one of the major nutrients you want your plant uptaking. On most PH charts that would mean your best PH value for maximum nitrogen uptake would be at around 6.5ph. In fact, 6.5 to 6.7, according to the chart, would be the optimal PH for maximum uptake of as many of the nutrients weed needs. Why do people say that 6.0 is where you want to be at?Ok so we are still sitting at the following conditions.

That charts for soil… in hydro we run a lower PH partially because we dont need to fight with the CECCurious...at the point that you are at in veg obviously nitrogen is one of the major nutrients you want your plant uptaking.

CEC... Yes....I forgot about that and the difference in grow media. Carry On!!!That charts for soil… in hydro we run a lower PH partially because we dont need to fight with the CEC
If at 5.5 then we are hindering our mG uptakeJust a random chart comparison i pulled without looking at so i have no opinion on the accuracy of this specific chart but just an example View attachment 1282405
Thats why i run low ph in veg and transition up to about 5.8-6.0 maybe up to 6.2 in later flowerIf at 5.5 then we are hindering our mG uptake
Second thought
Perhaps 5.4-5.8
interestingly potassium also struggles.
Nope bit it doesn’t end that abruptly imo… you can manipulate ratios and as @Moe.Red does as do i is allow a ph swing.So you reckon that graph is up the shit in sec pic then as 6.2 is out of p and k uptake..
