is this nute burn?

Hi Im on my first grow. im using aeroflo. strain: jack herrer.

I started out using the basic micro, grow, bloom solution from GHE. In first week of flowering i switched too Advance nutrients and started using Connossieur a+b mixing it with big bud powder an budfactor x. I have 70 L resovar and i start every week by mixing around
50-60 ml of each connossieur. then adding the big bud + budfactor. this give me an ppm around 700-800. then my ec is around 1.0 til 1.2 and then i keep feeding them connossieur rest of the week keeping the ppm meter where it should be. I been reading you should add all of the weekly budfactor x and big bud at the start of every week after changing water. I know u should at least use half of what the advance nutrient calculator tells you does this apply to the budfactor/bigbud also? I read alot the last week and i thought I figured out im been underfeeding them. so i upped the ec to first 1.4 then 1.6 then 1.6-1.8 in last days of the second week. then i noticed this around the tip of my upper leafs. what is wrong? after what i been reading i suppose to be going that far? anyway i watered it down too 700-800ppm again.im in 3week now. is this right? also i changed the nutrients from GHE to AN after 4 days in 1 week flowering, is this any problem? I also have an co2 bottle that i keep opening from time too time.i dont have any controller equitment yet but i figered it couldnt hurt!!!

Please help...

the burnt tips and clawing is telling you that the nutes are too high.

You may also be seeing the results of high temps, and you are wasting what co2 you have, for co2 to be effective it needs to be at a constant PPM.

regards,

I dont think its a heat problem. Its vinter here.. And the temp never goes over 27 celsius.. its around 23-25 celsius.. So its rather to cold.. I work with changing co2 tanks,So i get it for free so im not really wasting nothing..exept its not working I been watching my ppm meter and isnt the EC suppose to go up, if you have been overfeeding? I mean when i give then 1.4 in EC its keeps going down to 1.2 the next day.. I thought this means they are hungry? and isnt 700-800ppm to little in flowering? and should i add the full amount of budfactor x/big bud that AN tells you. Thats 140 ml budfactor in the start every week + 36 gr big bud? Or should i cut it in half?

you asked, you were answered. i never go above 1000ppm in aero and 600 in dwc, i pull 40+oz every three weeks, and i never have a nute issue. yet you keep asking if you should add more to the mix. NO. you need to lower it.
and although the co2 may be free, you are wasting it. the plants need a constant level to be productive. the up and down only confuses them.

Ok. Thanks for reply.. Im new to this so im only tryin to learn as much i can I didnt plan for this to go without some trouble along the way but i think i been doing it ok for the first time.. what should i do now. Do i need to flush? Or is it ok just to lower the ppm? And what do you mean by pull 40+oz every 3 week? Thanks for the help again

pic 2 seems healthy, except for a slight K deficiency(singed tips)... if it were nute burn, the new growth would shrivle and wilt very rapidly.

in the other pics the plants look like they have too much N, they look very dark, i would also suggest that you pay less attention to your meters(yes all of them), and just feed the plant by its looks, lime green= hungry. dark green = too much N(salt). pic 2 looks pretty healthy overall

lower your nutes.
and superstoner means he grows a fuck load of weed

only flush if your plant is burning bad, a flush will drown your plant for a couple days, when a plant drowns it cannot suck up nutrients so it will look "hungry" and it will start to eat the older leaves. your plant is not burning, just don't fertilize those dark ones for ~3 or so waterings

Okay thanks for all the input should i lower down on budfactor x and bigbud aswell? I use 140ml budfactor on 70liter and around 36g of bigbud powder?

just read the plant problem diagnosis it will suprise you, its the 1st and 2nd stickies
