Question for stinkyattic please

[marmarkus2006]

here is my latest pics of my first grow. after having recovered from
a calcium def. now i see this. here are all my stats and gear. This is a bubbleponic setup with 10 plants. under flor. lights. total lumens 7250, 6500k,

i am using hydrotek synergy series nutes.
from canadian hydroponic technology
2 part zeta grow part A, 5-3-1
nitrogen-5.0
potash-3.0
calcium-1.0
iron-0.1

zeta grow part B, 5-0-3
nitrogen-1.0
phosphate- 4.0
potash 9.0
manganese-.05
running both parts at full strength 1600 ppm

also part of the synergy series are the :
powerpak at 1ml per liter
magnesium-3.0
sulphur-3.0
copper- .05
iron- .2
manganese- .2
zinc- .05
also using this as a foliar spray at 2ml per liter as recommended on bottle started that today.

bee one 2-2-3 aqua max @ 5ml per liter
nitrogen- 2.0
phosphate- 2.0
potash- 3.0
calcium- 3.0
copper- .05

Dr fausts biomagic fulvic organic hydroponic activator and foliar spray 1:200 foliar spray once every 2 weeks
temp/humidity max 89/85% the high humdity was due to having used foliar spray.
min 68/ 46%
the average is 77-80 for temp and in the 60's for humidity
here are the pics of what i am seeing now.

some more pics hopefully this is enough for you to make a good guess as to what the problem may be thanks so much in advance

[marmarkus2006]

i suspect a potassium problem as i see none in my nutes.

[marmarkus2006]

So there i was getting freaked out over my plants. kinda like a daddy to a baby ya know. i called the guy at the hydro shop that has been recommending nutes and supplements. said hey check it out. took him a water sample. the two supplements, the bee one and the powerpak raised my ppm from 1600 to 2700 talk about nute burn. and to further that, the two extra supps, dropped my ph to like 4.2. flushed my system remixed my nutes and supps to 1000 ppm and then checked the ph. leveled it out to 5.8 hopin for the best. the plants do not bad at all. just showing some damage on a couple leaves. so i hope i caught it soon enough.

You have plenty of potassium in your nutes; it's the last #.
I'm not really a hydro troubleshooter, sorry.
Supplements can really screw with your grow... it's a good idea when using them to start out at a VERY low dose and gauge the plants' reaction.

[marmarkus2006]

I noticed more brown spots poppin up this eve. I think i will flush the system in the morning. Run straight water for 24 hours then reintroduce the nutes at 800 ppm. And stay off the supps. Honestly, I am lucky to have gotten them to grow as big as they have. Prior to this, everything I have ever tried to grow has failed. Thnx for the resp:hippy:nce

Awww....look at those beautiful babies!!;)can't wait til they're done! don't worry Babe You're doing an awesome job for the first go 'round!!Love you bunches!

[Weedhound]

Yeah, I'd stop and flush. You've put everything in there but the kitchen sink.....now take it all back out. I'd put them on plain ph'd water for a few days and watch the rez ph like a hawk. Your ph will tell you when to start your nutes back up......and I'd probably try a lot less.

[Weedhound]

Oh.....and.....get your humidity down if you can.....I'm told 30's is ideal and that's what I aim for. ;)

Check your rez ph constantly. The more off it gets the worse off the plants will be. :(

Bye
