Need help with first new time dwc bubbler grow!!

Hi all, IM a first time grower with little hands on experience. im using a 90 watt 3 watt led light for veg and growing in a tent. i use canna a and b for nutrients. my temps fluctuate between 22 and 27 more around the 24 25 mark. my plant is ak47 and is 4 week old from seed. im thinking from what iv seen on youtube and what i have read that my plant should be bigger but im not too sure. it all started from the second week when the tips of the first true leaves turned yellowish and started to die, they got that bad that the yellowish took over the full new true leaves and i had to cut them off. the yellow tips started on the next leaves and so on. i first thought it was a nitrogen problem so added more nitrogen to the plant, this had no real affect to the plant. i now believe that it is a ph problem but the ph is always between 5.7 to 6.1 never higher or lower than this. i will post some pics and hopfully you guys can help befor it is too late!!!! These pics are taken at different times of the grow....

Can anyone help please??

what's your ppm? and how close are your tap roots to the res water?

Yes PPM please. Consider adding B-52 and VooDoo Juice ASAP. My guess is your PPM are way too low for growth. My DWC plants were that big in one week easy.

Hi and thanks for the reply. I didn't no anything about ppm when I started. Can it be saved? I will have to go and purchase a ppm tester. What would you do in my situation? More feeding????

If not already done.Drop res level an inch below net pot.

The plant looks deficient to me.I would raise light to lower intensity.
I think you started with too much nutes or left res level to high,letting the roots get comfy,and not seek anything.
Less light intensity,lowered res to let splash instead,maybe lower nutes,and the roots should dip in res balancing things out.

if my plant was burnt wouldn't it affect all the leaves not just the lower ones? I think I will just put new ph water in and no nutes untill my ppm meter comes in a couple of days. Any more ideas?

The plant is taking from the lowers to feed growth.The roots feel comfy not seeking.I would just hold the net pot over a empty bucket and flush with a very lite feed.I would do that 3 times during lights on a day to get the roots to sek out more,and maintain proper res level for roots all ready out of net pot.

the res level was already an inch below the net pot. iv raised light and added new res with 2.5 ml of canna a and b, will that b ok for now? i will flush with this 3 times a day like you said. the plant is still growing and more roots seem to be appearing out of the bottom. my ph is a steady 5.8, i hope this sorts it!! will my plant fully recover? how long will this process take?

Plant should be fine.Different plants bounce back at different rates.Sounds like you have things handled.

Thanks for the advice, very much appreciated
