Could be worse I guess. It's makin somewhat decent buds. I know the plants yellow from the bottom up towards the end of flower but man...

these are nasty looking.

started from seed. 3 durban*skunk#1 females
day well 47 or so...
soil... uhmm... miracle grow, the big bags in 1m^3 - potting soil
used n guano, fish emulsion and p guano since flower...
430w son Ag hps











See how they are whrinkled, spotted, rusted, and severely yellowed randomly...? Lurks thinks it's over nitrogen... but needs to be sure... What of the yeild here/potency? Flushed em 3 weeks ago, seemingly well but obviously not well enough. Flushed again today after 1 week of dryness...

These black dots... insects? Don't see any anyewhere? No real indication of mold in the buds. Aside from one huge cola with very little trich showin, the other colas look decent with trichs. Could have more weight, but ain't gonna be picky now. Just hope to save as much as possible and come out with decent smoke. Fears to have screwed the pooch, but hopin after a couple more weeks, it will be smokable...

No mention of PH. Looks like lockout from nitrogen toxicity. You flushed but have you still been feeding the same regime?

fair enough... no mention of ph, never been checked. in three years of growin, this is the first time an issue as this has come. it has been stated that a serious grower will check the ph but at the same time it has been stated that these are weeds...

eh. lockout. it's agreed. as far as feeding, if was stopped as soon as this situation began with the yellowing. hasn't been fed anything except regular tap water (hard). did another flush today. well, the outcome remains to be seen. think there is any salvation or a way to make the most out of what is there? what is the best way to check ph in a soil based grow? how accurate is it?

hey personal grower, really appreciate the input.

These are weeds, and they will grow... But they will not grow to the best of their abilities without your help. You've been doing this without the use of a PH pen for all this time then don't change a thing if you are satisifed with the output. However, what you see here is either overdosed (you tell me, do you just eyeball the ferts?) and/or ph related.

Knowing the PH of your tap water, and it's good to check the PH of the runoff. My tap water has come out has high as 9 and as low as 7.3. If I had to grow w/o a ph pen it would be like driving blindfolded. You can have the best mix of nutrients in the world and if the PH is out of range it will never been uptaken by the plants and will eventually build up salts in the medium.

again, fair enough. ph pen. indeed. municipal water here runs between 6 and 7 consistently. it is checked in another location for another reason. never considered checkin run off. recommend a good ph pen? was considering doin hydro, and with that getting a ph/ec/tds meter. had an eye on the hanna combo meter. wanted to wait, but the logic is definitely there to go ahead and start improving the quality...

these plants are/were overdosed and are now most likely locked out as stated. looking at the sick plants sticky, minus the insects, these things are showing defficiencies in line with just about every description up there.

Sounds like your water ph is fine, you said it was hard water though, how'd you come to that conclusion?

Since you are telling us that this was an overfert, then flushing like you have with lots of runoff is the best thing you could have done... Not sure what else to suggest.

I finally broke down and bough a Hanna ph/ec/tds and so far so good.

Good luck.

A "Blue Reagent" "wide range" liquid tester, will usually measure pH levels from 4.5 to 9.0.
It uses a Color comparison method, with easy to read results, (assuming ones not color-blind).

Real basic, old school, low tech, but it'll let one know that they're at least in the ballpark pH wise.
Usually available for about 5 dollars (U.S.) at your local mega store or aquarium shop. Hydro stores stock them also, they just generaly run a couple dollars more at the specialty shops.

I hope this suggestion helps those on a tight budget around here who can only wish they had a pH pen.

Happy growing

I grow using similar methods to you mate, only with far less additional food. Looking at the plants I would suggest 3 things to check. 1. have you just put a new fan in there pointing at the plants, there appear to be what could be wind burns on them. 2. You could use a little ph down. a drop on 2 occassions up to this point would have been enough. 3. Stop overfeeding them, soil itself contains food for them, if they haven't finished eating and you startt force feeding them further, they are going to have their health suffer.

I.M. Boggled thanks for your input...anyone know a cheap TDS solution?

[Verite]

Good advice. My only two cents is that cheap ph testers give cheap results. When ph is fairly important and theres alot of difference between 6.2 and 6.6 it pays to get one that can measure that difference. Hanna makes an inexpensive battery op unit called the checker1 for about 30-35 usd.
