Leaves curling up badly

[tumorhead]

I've watered with pure water twice this week after overdosing them. They were too dry yesterday, a couple were sagging, so I watered.

I believe a week and a half ago I gave them some really low ph'd nutrient filled water, I've watered with 6.8 ph the last 2 times with pure water.

Just keep feeding plain water? Does this look like heat related or ph or nute overdose still? The thermometer says 80, they are pretty close to the light.

dude had the same problem with one of my plants. its no longer with me now being as though it hermed and got thrown in the fire...but im interested to see what people say. my temps have been "optimal" 70-80 humidity ~50 the whole time.

my idea of what is causing this for our plants and the thing i am fighting with right now, is my soil is too alkaline (its foxfarm) which is causing nute lock out. these plants need more acidic soil conditions and i think its either Phosphorous deficiency possibly?? or maybe something that can be fixed with cal-mag...but i dunno really know. i added epsom salt to the topsoil during watering's because it claimed similar effects to what cal-mag does but the epsom salt showed little effect, the new leaf sets would eventually though slowly start to get brittle and curl under like that. it was annoying

your pics are not much help btw but i would say heat back off the light give them water but get more ventilation they are baking in 80 if theres no good breeze they are plants not reptiles lol

They switched to bloom?.. I've had sativa dominant do that with high P nutes. They recoverd..I backed lights up also. Only the tops did it.

Oh I hope you are doing well. GammaKnife treatment?

that sounds like overdose new growth distorted small curl and fall off . they are weeds not trees

I switched to vertical with hps from horizontal mh and vegged for a week, then to flower 3 nights ago. A week and a half ago or so I fed like 3 different fertilizers and accidentally put a tablespoon of molasses instead of teaspoon in a gallon and they weren't happy. But at the same time the deficiencies I had seem to have stopped, everything is green, very dark green I think N overdose judging by some clawed leaves.

One problem is I don't have enough water, I only have 2x 5 gallon buckets I fill with tap water and let sit for 3 days(I've tried less and they didn't like it, 3 days seems to work best), but I have around 30 gallons of dirt, so not able to really flush them ever @ 3 gallons water per gallon of dirt....

To test the ph of the soil do I stick my meter in the dirt when it's damp or test run-off?

Oh I hope you are doing well. GammaKnife treatment?

Not yet, had follow up MRI on Mon after taking steroids for months to see if it shrank, follow up next Mon.

molasses wont hurt them none. its just sugar . as for the too much nitrogen .it will use it they grow pretty fast in flower but it slows flowering so if it takes a little longer thats why .

it didn't happen quite as dramatic as that. none of my leaves fell off they just looked like this.

1 -23w 65k 2 -55w 27k at the time, only had one fan circulating the air out. temps never out of control.

sorry to tumorhead in advance for hijacking his thread slightly, it just seemed our problems were mutual.

they look ok iratika hows yours doing tumorhead hope there doing better

Still same problem, watering with plain water again today, last watering was Tues.


They don't fall off, they just kinda become limp and curl under really crazily. They're growing though, it's the lower fan leaves not the new growth affected.

as long as its old growth dont worry they shed there leafs as new growth comes .but could be not enough water a good size plant can use a gallon a day in summer but idk your medium i water every three days real good even seedlings i never go a week and im running soil root rot is something thats happens in hydroponics imo hope this helps
