vWhat type of medium; hydro?
What brand - hydroton
Indoors or outdoors? indoors
What strain?sour grapes
How old are the plants? clone, 1 week
What type of lights and how many watts? hps 600 watt
How far from the lights? 3ft
What is your watering frequency and source of water? DWC/ RO
What, how much and when was it fed? NPK? lucas formula
What is the medium/runoff pH and PPM if in hydro? unsure ph in res said 6.0
What are the temps and humidity in the room? 75/35
What size pots? 5 g
Any bugs? Look real close.no
Any other pertinent info? yellowing, older leafs have burn like mark. stems are purple which i read is caused from lack of P. i think the other issue im having is a mg or cal mag maybe not sure. also the tips are curled upwards and tips are all yellow burnt lookin not on all the leafs but sure seems like its spreading !

i flushed the system todays ago. if i did it correctly when shoulld i see results ?
how can you tell between a lock out and deficency ?
i have new growth almost everyday
i know if it isnt broke dont fix it but it looks like its spreading sooooo... any help ?

lower you ph till about 5.8
your feed seem to high what the eec or ppm should be about 12 and purple stems is a sign of low temps also a good thing to have hanging about is calmag but i dont think its a cal or mag deffiency my guess is nutes to strong flush which cause lock out hydro is the easiest to grow at if you have a good ph metre and eec truncheon flush with ph adjusted water again if things dont turn around and things should turn around and for security reasons get a balaclava

happy growing

I think I know what is going on.

The low humidity in the room is increasing your plants respiration rate despite the temperatures being reasonable. Transpiration can REALLY eat up a lot of K, which will then limit the amount of P the plant can utilize. There is also a slim chance that the angular reflection from the foil is creating hot spots.

My solution for this would be to get your humidty over 40% and closer to 50% until you get some buds on there by leaving a bucket full of water in the room near a fan. Supplement your fan leaves with a weak 0-2-4 nute solution foliar spray until it looks the way you think it should. All in all it doesn't look too sick or bad off.

oh ok that makes sense, ill try to keep humidity up i can real easy when the light is off but for some reason when the light is on with the bucket of cold water it just loweres the humidity. any other suggestions ?

i had the same problem, i put a couple cfls on them untill about a week before 12/12 the HPS lights are very intense for small/medium sized plants.

Best suggestion I can think of if that won't work is a humidifier. Vicks sells a cheap one that heats the water for like $15 at Target. Most others will run you around $30.

hey, the older leafs are all starting to get these yellow spots in the middle and outer edges. should i use a folier spray with minor nutes ? i dont think its lock out any suggestions??

IM GETTING THESE MARKS ARE ALL THE LEAFS AND EDGES IVE FLUSHED SYSTEM SEVERAL TIMES AND CORRENT PH, PH IS NOW 6.0 TEMPS AND EVERYTHING IS GREAT...ANY HELPP ???

First off... I don't know.

But... They look a little droopy. Ok, so maybe they don't have enough water at the main root ball... That's one idea. You could increase the level of H2O into the netpot to look for improvement. Or I could be wrong and they are water logged... in which case you're going to need to drop the level. I can't see in the bucket so that's your judgement call.

Scale is a little tough to judge but they also look a little stretchied. Maybe on purpose... I dunno, but that could be a sign of not enough lumens. The extremely oversized upper fan leaves point to that as well. Or I could be wrong and this could be some outdoor plant genetics growing indoor and it's just pissy about it.

Then again the leaves do look pretty healthy colorwise. Maybe the edges are turned up a touch, but that could have been stress enduced from all these flushes. Or I could be wrong as some of the stems look a little purple, maybe from a P deficiency.

And is that plant topped? Could this all just be stress induced from that massive amount of trauma?

ok well thanks for the reply. the huge fan leaves are startin to get a little bit of spots but im not gonna stress to much over it anymore i reflushed again yesterday and today it looks way better and pretty healthy i woke up this mornin and the ph dropped though to 5.5 so i readjusted to 6.0 and noticed alot of water dropped so we'll see what happens. the plant is sour grapes and i got it from a sacramento club i found out afterwards this plant is a real bitch for a first grow. i read it is real picky on food. i also upped like 2 ml of the lucas formula. the stretching is probably because i have my light pretty high up ecause it is HPS during veg. thanks again

It's been my experience that those brown dots are caused by acidic pH more often then naught. And I see you had a bit of an ish with the pH today so that all fits. I'm growing some BC Big Bud x G13 x Hashplant right now and it is anything but tempermental. Though my first grow was some Durban Poison so I can totally relate because I had nothing but problems with them.
