coco plant burnt leaf symptoms?

Hey everyone so im a first timer growing in coco and everything was nice and healthy but like 5days ago or more my plant started showing thesr symptoms my new growth is dying and my leaf edges look like theyre burnt or spmething look at the pics below this plant is abt month old from seed strain is rasberry im feeding ghe flora 3part atm giving 5ml flo mic 5ml flora gro 2,5ml flor bloom. I just got this tent they were in a closet but it had really low humidy .

Oh and also im using 150w hps for veg like 3weeks ill be gettinng a 600w dual spectrum and atm humidy is 55%

what are you ph ing at

6,2 - 5,9

Its getting worse now more leafs affected

Do you have an EC or ppm meter to measure the runoff ec? I'd drop back the feed to half strength and feed with a descent amount of runoff.

Gave her a weaker feeding today 3ml flora micro 3ml flora gorw and 1,5 flora bloom per 4,3 litres hopefully this plant gets better now my soil plants look so much better and very happy im not sure if im ever going to grow in coco again

I find it almost impossible to mix small volumes of GH without an EC meter. Perhaps the solution is too concentrated but when I look at one of your pictures, I noticed a residue on one of the leaves. Sometimes a leaf or two get similar spots if the solutions gets on the plants when I water.

Coco is a very forgiving media to grow in but you would probably need to add some CalMag later. Except for the spots your plants look healthy. I wish you good luck with your grow!

Thx im gonna order an ec meter at 30th day of this month the plant looks but healthier today
