Defficiency? PH problem? Need help figuring this problem out.

All my plants are just over 2 weeks into flower. They were vegged for 6 weeks. My 3 shiva skunks are doing horrible (all other plants are other strains and they are doing great) they were started as clones. In veg they were doing great, growing more vigorous then the other 2 strains I am running, then as soon as they got put into flower they slowed down in growth, and the leaves look terrible. The leaves are cupping downwards like a claw, and some leaves are curling up. Some leaves are getting brown dead spots and turning yellow.

I would like to add that I havent been adjusting the PH at all. I have a digital PH meter but was getting inconsistent test results from the run off. I now have a soil tester and it looks to be way too alkaline. when the probe is in the top few inches of soil the PH reads 7.5 and when i get down to the middle of the pot it is about 7.

Also would like to add that I flushed with 2gal RO water per pot last night.

Temps are usualy around 80f, humidity in Veg was about 50-55% but I now have a Dehumidifier so its usualy around 30%
They are on a 12/12 cycle and 18inches under a 600w HPS
They are in a 60/40 mix of Happy Frog/ Perilite, with dolomite lime mixed in (1 tbsp per Gal)
Thanks for any help you can offer, I need all the help I can get

nute solution burn.

You think its nute burn? Well if that is the case how long should it be before I see improvments after flushing? and i thought Bute burn started at the tips and edges and spread in, my leavs are burning from the inside (like the veins) out.

some kinds of nute burn start showing at the leave tips but not all.
read the link i posted.
badly damaged leafes wont recover by flushing but go ahead and flush them if you want and cut back on the nutes.

have you tested and got your ph in order ????????

Thanks for the help man, I already flushed last night with 2 gal water each and they are in 3 gal pots. Is this enough or should I flush again?

yes it wont hurt to flush again but just keep checking the soils ph level untill its all good.

Flushed again tonight, 2 gal per pot. One plant has started to come back, but the other two are looking even worse.

looking worse in what way ?????.
if they are drooping then its normal if you have ran alot of water through them.
can you get some more pics.
Potassium (K)
Potassium is involved in maintaining the water status of the plant and the
tugor pressure of it's cells and the opening and closing of the stomata. Potassium is required in the accumulation and translocation of carbohydrates. Lack of potassium will reduce yield and quality.

Potassium deficiency (K).
Older leaves are initially chlorotic but soon develop dark necrotic lesions
(dead tissue). First apparent on the tips and margins of the leaves. Stem and branches may become weak and easily broken, the plant may also stretch. The plant will become susceptible to disease and toxicity. In addition to appearing to look like iron deficiency, the tips of the leaves curl and the edges burn and die.
Potassium - Too much sodium (Na) displaces K, causing a K deficiency. Sources of high salinity are: baking soda (sodium bicarbonate "pH-up"), too much manure, and the use of water-softening filters (which should not be used). If the problem is Na, flush the soil. K can get locked up from too much Ca or ammonium nitrogen, and possibly cold weather.
Potassium (K) Toxicity
Usually not absorbed excessively by plants. Excess potassium can aggravate the uptake of magnesium, manganese, zinc and iron and effect the availability of calcium.
Why do my plants droop after flushing or heavy watering?

They droop after flushing due to lack of O2 in the rootzone. Take a thin wood dowel or pencil and poke some holes down into the mix for aeration.

They dont really look "droopy" they are still curling and twisting like before, and I have flushed twice. here are more pics

Sulphur (S) deficiency
The initial symptoms are the yellowing of the entire leaf including veins usually starting with the younger leaves. Leaf tips may yellow and curl downward. Sulfur deficiencies are light green fruit or younger leaves with a lack of succulence. Elongated roots and woody stem. Although it's hard to see in figure 19, the upper stems of this plant are purple. Although many varieties of cannabis do get purplish stems, the trait generally extends the entire length of the plant's stem, and not just near the top as in this specimen.



Figure 18.

Sulphur Toxicity
Leaf size will be reduced and overall growth will be stunted. Leaves yellowing or scorched at edges. Excess may cause early senescence.

I really hope some one can help you out with this one. My cousin's girlie (ogx of some sort) is doing the excact same thing with the cupping downwards. The growth of the plant seems to be doing fine....alittle on the light side of color but really just the curling thing.
Its like u search and search and everyone has the same few links which end up being the same guide pics which are Top Notch dont get it twisted , its just that no where can u find a Pic like yours with the leaf cupping and pointing down like that. So PLease someone help out!!!!
-thanks for the post...

LUDA.

Is your room completely light tight? The strong curl can be signs of a plants light cycle being thrown off.

the room is light tight, but the door gets opened breifly (like no more then a few seconds) from time to time (like mabye every other day) The plants look worse then ever, Im thinking about pulling them and getting started fresh with another strain. Most leaves yellow, curled and over all sickly looking, not many leaves, small buds. Will snag some pics tonight when lights come on

here are some pics
Plant one, worst of the bunch, leaves yellowing and dieing, small buds, top leaves curling up






Plant two: less yellowing but severe leave curling downward especially on buds



Plant three: not too bad off, but definitely not healthy, some leave yellowing, smallish buds, some curling


And here are all three together

also like to add, they are in week 5 of flower under 600w HPS temps usually around 80

anyone?????????

looks to me like the ph is fucked ? did u only add the dololime to your dirt one time before u planted in those pots? they dont look as bad as your makin it, but i see your concern! 40% perlite in happy frog is alot of perlite, so maybe you are underwatering ? it would be hard to overwater those............... which food are you useing and how much ? those last 2 have really good color, are u sure its not under or overwatered?

They might not look that bad in the pics, but they are pretty bad looking, I will be surprised if I get a half oz off each of the first two. and i guess it could be under watering, but I use one of those soil probes and water when it is almost in the red. And the lime was mixed in with the soil when they were first poted. should I just not use lime in the next run? I was told it would stabilize the PH and it is usefull when using RO water.

yes keep useing the lime , i was just makin sure you wasnt useing it more than that..... it does help with the ph. Those things look like they can easily drink 1/4 gallon a day. the first one looks kinda overwatered but i cant really tell. i just pick the pots up and kinda judge by weight , if they are really light then they need water , if heavy then no water.
and yea if u let um go they look like they will get close to 1.5 oz total at LEAST , but i am just guessin.............?
