Please Help

Well this completely sucks, my fast buds strawberry auto is sick! I went to my grow tent after not being home for a few days and unzipped my tent to this. The leaves are turned up, twisted, and crispy. The leaves that are not like that have a rust looking spots. I dont think its nute burn because i only feed her half of what the directions call for. Early on i did have a problem with high humidity (fixed now). Anyone know what is going on? At first i thought nute burn so for the last few days i have been feeding her straight water. I and my girl really use the help, thank you!

Day: 53
light: bestva 1000 on 18/6
Medium: 60/40 fox farm coco and perlite
Humidity: 45-50%
Temp: 70*
nutes: fox farm big bloom, kangaroots
Autopot w/ air dome

Please help, this is my first autopot grow and its not going as planned.

Your growing in coco? Did the problem start before or after you started using plain water? never use plain water in coco. just never, always a weak nutrient solution if you're trying to flush it. definitely don't use plain water over the course of multiple days.

Thank you for the response. The problem started before, i started really diluting my reservoir after i seen what was happing in case it was nute burn.

What's your ph? Is it coco or cocoloco?

Have you just been feeding with big bloom and kangaroot the entire grow?

Overall, that looks a bit like P deficiency. Big bloom and kangaroot are primarily micro/myco supplements (not base feeds) and don't have much N or P. If I'm looking at the correct labels online, 1/2 the recommended dosage would only provide ~10 ppm N and P each, which is way too low.

Yes i have been feeding those the entire grow. What brand would you suggest getting?

You need to feed at minimum the Fox Farm Trio. Big Bloom, Grow Big and Tiger Bloom and probably Cal Mag depending on your water since your in coco. Your lady is in flower and at that stage you should be feeding 550-650ppm ph'd to around 5.8-6.1. Fertigating at least once a day til 20% runoff. Probably needs twice a day really

If you want to stick with the fox farms line-up, the recipe below should be good enough for where you are in flower. If you are using tap or well water, it will need to be adjusted to account for the calcium. Make sure to adjust the pH as needed.
