How long has this problem been going on?
Ever since I got these babies. Always a problem going on, cant keep them all fully green!
What STRAIN are you growing?
What was the establishing technique? (Were the seed or clone?)
What is the age of your plants?
Multiple plants; all varies around 1-2 months
How long have they been in there mixture they are in now?(coco,soiless etc..)
ProMix BX, transferred from Rockwool (clones)
How tall are the plants?
Between 5-8 inches
What PHASE are the plants in? (seedling, vegetative or flower) are the plants in?
What Nutrient's are you using?(If growing soiless)
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
0 Grow -5 Micro -10 Bloom per 1 gal, Feed every third watering.
How often are you feeding? (If using soiless)
Watering when the soil is very dry, leaves droop or about to droop. (Once every two-three days w/ slight runoff)
How often are you giving nutrients? (If using soiless)
Feed every third watering, Never got to the third since I flush alot :(
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
Micro first then bloom
Are you sure your calibration is correct on your equiptment?
Yes, three point calibration a few days ago
When was your last watering?
What is your water temps?
When was your last feeding change? (ie. grow-bloom-micro-additional)
About 3 weeks ago, changed from 1/3 str lucas every watering to full str every 3rd watering.
What size bulb are you using?
What is the distance to the canopy?
What is your RH Factor(Relative Humidity)?
What is the canopy temperature?
68-81F, 69F Average
Tell us about your ventilation, intake exhaust and when its running and not running ?
Open door, with one fan blowing in and one low setting, circulating over tops canopy
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? R/O Water at 5 PPM
Has plant been recently pruned, cloned off of or pinched
Yes, recently topped 11 days ago. But these problems were showing before that.
Have any pest chemicals been used? If so, What and When?
Are plant's infected with pest's No,
Im using ProMix BX with dolomite lime in 6in containers. They are about 5-8" tall. The strain is purple kush. I have multiple problems, alot which I cant identify even with the guides or searches. Third grow, but the first two times I was young and didnt really pay atttention to deficiencies. This time I want to do it right. I water with 5.9 R/O water at 1000> PPM (Lucas 1/3 str was around 300 I believe and full str is around 900. Runoff today was around 100-400 ppm @ 6.1-6.5 pH watering at 5.9 pH R/O.
This is one of the healthiest ones I have.
Problem 1: Twisted leaves
There are most twisty leaves if you look at the rest of the pics. This one was just a closeup. I heard the twisting can be because of the strain. PK/Purple Erkel, but Im thinking pH?
Problem 2: White Spots
Problem 3: Purple Tips
Both problems can be found on these pics. Purple tips is a P def I was told. Maybe just a pH lockout?
The Underside leaves of them. I have scouted for mites or bugs with eyes, 40x loupe and also using a plain white paper and gently shaking/brushing leaves to see if anything falls on paper, and found none. I check every day.
Problem 4: Leaves that grow out just fine and healthy, but as they age and get larger, they turn into yellow, rusted, drooping, older fan leaves.
They start like this.
Then end like this:
Problem 5: Rust on the leaves (pH problem or Mag?) I think it maybe a lockout as well since I have dolomite lime.
Problem 6: pH problem I believe. My runoff pH WAS 6.6 with 5.0 pH RO water, if I water w/ any higher pH then runoff will be 6.6-7.0, I think because of the dolomite lime, should I change my RO water pH to 5.9 and keep it at that regardless of the runoff? I cant seem to get 5.9 runoff :( because the more I water the higher (Alkaline) the pH goes.
For instance I first measured runoff of my media. It was around 6.5. I decided to lower it about .5 so I flushed it (3x size of container) with R/O water pHed at 5.7 (I was told soil would be .3 up or down of runoff)
The pH stayed the same when I checked runoff, so I lowered to 5.0 pH, and the pH went UP!!! So I stopped flushing, I think the dolomite in the soil is activating hard so its just balancing it out. SIGH
I checked runoff again today; I watered at r/o water 5.9 pH and it was at 6.1-6.6 pH, 100-400 ppm
I water them when they need them (when the soil dries out and the leaves sag just a tiny bit) which is about every 3 days. I had been flushing them alot since the white spots and other deficiencies occurred which started ever since I got them. They were in bad health when I picked them up.
I used to feed them 1/3 Lucas formula, but I seen some def's so flushed and I changed it to Full Lucas, the new growth seems green and healthy now, but the hurt leaves doesnt look like they are going to recover back to green.
During the time of pics I already changed to full Lucas formula (GH Flora : 5 micro, 10 bloom) every 3 waterings. New growth appears very healthy now, but the other leaves that were "hurting" doesnt look like they are recovering, is that normal? They are the bigger fan leaves. Should I just clip them?
I got abit of nute burn with the full lucas, so I flushed it again a couple days ago.
Here are some pics.
My questions would be:
1.what are the white spots/rust spots/twisting/yellowing bottom leaves caused by?
2.The plant was not fed anything when they were in a cup while as clones and thats why the older leaves are yellow (I believe) (They were new growth and turning yellow so I fed them after, but they never seemed to recover?) and always drooping (while green leaves dont) regardless of the media being wet or dry, but I have started a feeding program a month ago and the new growth is nice and healthy BUT the older leaves that were deficient are not recovering from the "yellow" rusted state, is this normal? and should I just clip them?
3. How to control the pH. I mean promix is a handful for me, first I had problems with it being to acidic, now when I transplanted I added dolomite lime to my mix, and the pH seems a tad high for soilless. Should I keep watering with very low pH water to get the "perfect runoff"? Even at 3.0 pH?
4. All the plants has healthy new growth but soon as they get older they start fading off to yellow and almost dead. Why is that?
Need help asap, thanks for dropping by.
