A little advice from the wise people who know more

Im just looking for a little advice from more advanced people.

I am growing auto flowering ak47 using a bubbleponics system (first-last time) I will be switching to the rockwool with drip line watering as soon as i get my delivery.

Ph is at 6 right now
Fed with fox farm nuts.

I know my initial problem was way too much Liquid Karma which happened twice due to my own stupidity the first time was when it was only about 8 old and over watering when she was young. The leaves would curl and would turn yellow/brownish then dry up and die. The last time was at about 30 days so I flushed my system and corrected the issue. After this most of the plant especially the newly grown levels were a nice green but the bottom and some of the center of the plant are still pretty dry and colored. below is how it looks. and my other issue is below.







My other concern is there is a white sugar like substance growing on my roots and was wondering what i can do it fix it or if it isnt something i shouldn't worry about.



Thanks everyone in advanced

no one has any ideas at all?

too hot and too much food.
how far on are you?.
vegg or 12/12.
the more food you give will just kill the plants if you feed too much

Thanks for getting back to me crazy

i was on 18/6 and just switched to 12/12 a few days ago. The heat should be fixed now i just built a grow box and the air flow is fantastic. I am using 3x duel spec 2 flowering lights maybe i should go down to 2?

leaves look like ph imballance. if from old damage it wont fix it but as long as new growth looks good you should be fine. i dont know much about the bubbleponics thing but the whit build up might be calcium from the water your using?

Thanks again the PH was my concern before because i lost my ph kit and didn't have the money to buy one for a few weeks. but if it sticks between 6 and 6.5 it would be ideal for flowering or am i mistaken?

Should i trim the dried leaves or just leave em there?

As for the water i use RO bottled watter but maybe thats just unavoidable. its been there a few weeks you think if it hasnt hurt it yet it will continue to be ok?

did you feed anything else at the time of liquid karma. because thats a supplement and needs to be used with other nutes. i made the same mistake using that stuff by itself when i started and it locked me up tighter than a nuns, well you know.i did a flush and hit with bloom nutes and i was back at it.
not sure on the ph level for bubbleponics but i do believe you should be ok it is a little higher for me in soil. if more than 2/3 of the leaf is fucked cut it then. if it hasn`t killed them yet i would think you will be ok as long as it dont spread. what iv`e read is in hydro you may only have a matter of hours to fix your plants or they die, thats why i like the soil better it gives me more time in that case. replace your ph tester.

when i did karma i did cal/mag and grow nuts but i put too much karma because i did what it said instead of 1/4th that(only on the karma) and i was stupid enough to put them all in at the same time without first mixing the water then putting it in thus the roots more likely then not sucked it up as soon as it hit the water.

As soon as this baby is done im switching to a rockwool/drip system i think ill have better luck
