    Could low humidity do this?

    Cheers 2H! Aaaahhhh she stil not happy. Ppm has been consistently rising, eg 1100 to 1200 overnight. So did a rez change she has 975 now, really hoping that drops which will tell me she is feeding...theres some yellowing on the leave edges. Not for the first time im thinking - she seems to be...

    Dwc rez change and smt gone seriously wrong!

    Hi guys, I think it was a number of things, low humidity, pH going wonky very quickly. She's still showing some rusty spots here and there, but otherwise I think she's gonna be fine. Water here is excellent, except in my flat which has weird plumbing, I have my doubts the water is 100% clean...

    Could low humidity do this?

    I dunno, she definitely improved after i added calmag. Scrog/hook system working well, lift it, hook it and its out of the way and i can do stuff in the rez. Scrog way bushier than id hoped, I think i need to defoliate a bit! Will flip her this week.

    Could low humidity do this?

    The rusty spots are very VERY rusty coloured...its more a case of damaged leaves getting worse than the damage spreading but still i dont want it! Looks very similar to initial symptoms which improved with CalMag...so im tempted to give her a bit more and see how she does...

    Could low humidity do this?

    Cheers. Man...weird shit going on in bucket. Since rez change about 10 hours ago - ppm up from 1200 to 1320, ph up from 5.8 to 7. They are both flying up...and i have no idea whats causing it! Any ideas?

    Could low humidity do this?

    Ok many thanks for the reply. As you say pH/ppm levels aren't right (just checked overnight, ppm up 200, pH up to 7!!) basically I'm letting things drift far too much. I check/readjust in the morning, I really need to start monitoring a bit better, eg checking before I go to bed. Will do a rez...

    Could low humidity do this?

    Hmm. Ok! Any ideas what it might be then? pH was up to 7 this morning too high i know, but i dunno if plants would react that quickly when the pH is off...? Cheers!

    Could low humidity do this?

    Is this the calcium deficiency too? Quick look online and i thought yep looks like it.

    Could low humidity do this?

    I think it was a few things, i moved her into my living room which had crazy low humidity (20%) which didnt help, plus cal def, she definitely improved with added CalMag as suggested by the guys here.

    Could low humidity do this?

    Scrog update if anyones interested...she's not quite as evenly spread out as id like, need to fill the two nearest corners. There is some tip burn i think thats the nutes, im throwing a bit more at her than i probably should (ppm rising 60-80 over a day). Otherwise i think she looks great, hope...

    Could low humidity do this?

    Cheers :) My first scrog, its kinda fun tucking and tying the tips down! Yeah i just drilled holes 5cm apart and threaded some string through to make the net. If youre interested...? https://www.rollitup.org/t/super-simple-scrog.1017446/

    LED for single autoflower

    I do exactly what you plan to - single plant in 2x2, knock off basic QB288 135w jobby think i paid maybe 140? Its been brilliant. Ive got 1.5g/w easily, actually both my grows i lost maybe 20% to mould (my fault, need more ventilation) so thats probably more like 1.7g/w.

    Super simple scrog

    Hiya Pics are self explanatory, i thought of a few ways to support the frame with something attached to the dwc lid but i imagined that would be a pain. 4 hooks in frame corners, clip onto string strung to tent poles. Great thing is i will be able to just slide it up when i need to remove the...

    Could low humidity do this?

    24-28° or thereabouts. Yeah ive been thinking all along it might be a deficiency. Gonna bump ppm up from 900 to 1100 and see what that does. Will read up on VPD. Thanks!

    Could low humidity do this?

    Hiya My other thread has died so ill ask here - 6 wk old DP Strawberry Cough in DWC under basic 135w QB. Temps, pH, normal, ppm is actually dropping 100 a day so shes feeding. Overnight the damage spread a lot, and the only thing was different was that the humidity dropped pretty low, 35%. And...
