Help! Why do my babies look busted?

[Leauxla3]

Hi all!

So I'm approaching week 9 (Tuesday) on my first grow & my girls (orange sherbert and lemon pie) are starting to look raggedy. The OS has some fan leaves yellowing along the sides and the LP has the top leaves curling, routed brown spots and the texture is very dry/crunchy.

I have them both in a super soil mix consisting mainly of coco/perlite/peat moss. I started off by blending in some great organic nutes at the beginning of the run and throughout the grow I have been using Dr. Earth dry amendments. Nothing has really changed in my routine, humidity has been around 55%, & temp is around 21 - 22 C. I haven't had any issues until the past couple of days. I did check my ph of my soil and is around 7.5 - 8 & the plants are showing deficiencies. I'm assuming it's a nutrient lock out due to alkaline soil & the signs of deficiencies.

How should I proceed to attempt to save them? I'm afraid to do a flush because I do not want to kill all the great nutrients in the soil. Is there a way to lower the pH of my soil to try to salvage my girls? I just don't know if I’m freaking out over nothing because I’m not 100% not sure if this is something that normally happens right before harvest?

Simply drop 2-3 drops of lemon juice to an 8 fl oz (240 mL) glass of water. The acidity of a lemon naturally lowers the pH level of the glass of water. You could also just drop a lemon wedge into your water to give a stronger flavor and lower the pH maybe that could help
If pH is the problem no picture so harder to say but i lose leaves sometimes in flower especially towards End.

@Leauxla3 Welcome to AFN Do you have any pictures?

Well my experiences here on AFN do not show good results for that type of soil blend. It is easy to get the nutrient balance out and hard to get it back but your problem may well be the PH. Don't do anything drastic. Just water and fertigate at PH 6.1 This will gently bring down the soil PH. The plant can also make some corrections as well. Lemon juice is not persistent so it is better to use a commercial product.
