New to hydro

[HydroSpice420]

I have a 2x2 ebb flow w/ a 150 watt hps and 2 2ft T5s. There are 8 plants 1 is a strain called sailor spice started from seed and the other 7 are from good bag seed. They are all about 3-6 days into flowering. Most of the plants are showing some spots and color change on the leaves.
I used Humbolt organic Grow nutes for 2 weeks of veg time. I mixed 50ml into 10 gallons of distilled water each of the 2 weeks. 6 days ago i started using Humbolt organic Bloom nutes. I mixed 50ml into a new 10gal of distilled water. The spots were first noticed 5 or 6 days befor switching to the bloom nutes.I use a liquid ph tester and have kept the ph beetween 6.0 and 6.5, it has been close to 7 but never higher. I have it flooding 3 times a day for 15min.
here are some attached pics i took today. Any advide would be greatly appreciated

They went into shock. expect a two week delay untill harvest weight is met. looks like light burn on the last pic. keep ph at 5.8 for most of its life and 6.0 during ripening.

hope I don't get slammed for posting a different site here, but I wish I had read this when I first started hydro: http://www.cannabis-world.org/cw/showthread.php?t=574

What not to do in hydro

--------------------------------------------------------------------------------

Thought the info should be posted here. Following many of these would have saved many plants for many folks.

Dont let your garbage build up, keep your area clean, even behind things. That includes your measuring devises too.

Dont run your PH meter more than a month without calibration.

Dont run a hydro setup without a thermometer.

Dont guess at what you are doing !! ASK .. before you add 387ml of xyz and then need to post in the First Aid forum a thread that starts with "HELP" I added ....

Dont run without a spare bulb, Murphy lives with any grower !

Dont be afraid to ask, what is more important .. your itty bitty ego ? or your plants ? Honestly no one will remember your 'dumb' question... except for the assholes who read it..and say .. geee I wish I had the balls to ask that.. its something I always wanted to know..

Dont take cuttings and not mark them, saying "I know what they are". Doing so will usually require at least 60 days to confirm.

Dont chase PH !! if your res is outside the norm of 5.2 / 6.1 there is a reason for it. mouse in the res..pee in the res.. hehehehe..
at .16 (sixteen cents) a gallon for the Lucas formula.. just dump it.. wash it out..and refill it..

Dont assume no one will come in. Get N E W locks before you start and use them .. always

Dont overlook the security forum. there are a number of priceless posts in there. Why priceless ? Cause they will keep your ass out of jail !!

Dont trust anyone with who you are. Not until they have proven themselves to you and others. Again, its your exposure to jail.

Dont chase THE new strains. Those same strains will be won at real pricing in 6 months. (hr isnt into beta strain testing ..heheh)

Dont chase THE new additive or nute. A properly run hydro setup, e/f, NFT, DWC, aero, drip, wick, gravity feed or what ever else you can dream up works best with simple proper nutes such as proven by now 1000's of growers who use the Lucas formula.

Dont wait to ask for help thinking it will be allllllll better tomorrow.
The moderators of CW's First Aid forum are damn good with any type of growing issue but you are dealing with a living enity. If she is sick.. get the Dr. involved NOW.. not in 3 or 4 or 5 days. Solve it quickly and your plants will show their love !!!

Dont ask 17 people for help with a sick plant or res and 'average' the input. Pick one, max 2 people who you respect and do EXACTLY what they say. Their input is based in experience. If its not, why are ya asking them anyway ??

Dont think bugs or critters will go away either. Genocide is the only appropriate way of dealing with them. Dont think that in 2 days because ya havent seen any that you won.. most take at least 3 days for eggs to hatch. Repeat the treatment in 3 or 4 days.. . repeat the treatment in 3 or 4 days.. repeat the treatment in 3 or 4 days. THEN you with know you got'em but only if they are gone.

Dont be afraid to build your own equipment. Doing so will teach you a great deal about the how's and why's of hydro.

Dont throw money at your grow... take the time to plan, to research , to find out the pro's and con's and examine your options.

Dont go for more than a week between checks outside for bloom light leaks and for odor and for noise.

Thats most of the dont's that come to mind instantly.

I use a liquid ph tester and have kept the ph beetween 6.0 and 6.5, it has been close to 7 but never higher.

Ola!!

All that's happening is your PH is too high which is cuasing nute lock. The fan leaves are flusing out stored nutes through it's root system in order to feed the plant and save itself.

A rumor got started in the hydroponic world that the correct PH is 6.5, 6.8, 6.2 etc. etc. I honestly, really have no clue where this rumor was started and why it's still professed today.

I kept mine between 5.3-5.6 in flower and 5.6-5.8 in veg for my particular strains. Any higher than that and my plants would burn.

Please see what 'King' has to say in this thread. He's a real experienced hydro grower and has pictures to back up his PH levels.

I like this phrase the best "You guys are locking out your nutes going above 5.5. 5.2 is optimal and that's what I'm at 24/7".

Your strains might want something else though. I found 5.5 worked best during flower. Also you have to change your resevoir weekly or you will have an imbalance of nutes and minerals in the tank eventually which will also cuase problems.

Remember, the key to successful hydro is a stable PH at the required level (needs tweaking every day or 2 unofrtunately. get a glass eye dripper from the pharmacy and measure how many 'drips' it takes in your resevoir to get your PH down .1) AND the key to success is.... unortunately... completely changing the resevoir weekly so your always at a balaned nute level.

Crush - I'd like to know where you learned to change your reservoir weekly. I only change my rez once throughout the entire grow! (veg to flower)

Also, if you're adding back the nutes correctly you should only have to adjust ph once or twice. Chasing the PH every other day leads to a lot of other issues...

Not trying to bag on you, I'm genuinly interested as this is the first place I've read that stated weekly rez changes are necessary. TIA

update

update

ive been keeping the ph around 5.5 to 6.0. I mixed the bloom and grow half and half. They responded very well to the full dose of nutrients but started showing some curling and browning of the tips of new leaves the last 2 or 3 days. Today i made a new mix of nutrients about the same as before just a little extra bloom. I had some pictures of the new browning and curling and one of all 8 but the upload didnt work and i had already deleted them from my phone. I should have some more pics later.
