Hi! I have two plants AK -47 (right) and WW ( left) end of week 4 flowering. Are these yellowing leaves with brown spots normal, also have some brown tips. I dont want to spread to my beautiful nugs and sugar leaves. Only the AK seems to have it. 1000 watt LED , Using FF ocean forest and mammoth P, and just gave a dose of Tiger Bloom. Am I ok???

This is something you need to correct ASAP. Check your PH to make sure it is 6.8-6.9 and give the plant some CAL-Mag. Also make sure your lights are 18-22 inches above the top of the plant.
 
Ph is normal usually the runoff is on the acidic side like around 6.0 ish maybe a little less maybe more, have been using distilled water mostly, but also use up and down when feeding
 
Check your Ph levels in the soil and not just the run off water.
Make a flush with PH’ed water or give the plant some supplements for the roots. Like voodo juice or root juice.

How big is the pots ? And how much water are you feeding them and how often ?
 
They are in 5 gallon fabric pots and only the AK seems to have this problem. I give them like a gallon between the two plants every 3 days or so. How do i check the soil ph itself i only have the drop tester not the digital probe
 
They are in 5 gal fabric pots. I give them about a gallon between the two plants like every 2-3 days. I havent been feeding them much besides mammoth p every week and a little big bloom that stuff doesnt do anything. Gave them 1 tsp/ gal of tiger bloom with ph up last night
 
Using a digital one. It’s way better than the strips.


Honestly all that bloom and fertilizers haven’t helped the plant at all if it’s having a lockout from bad Ph levels or salt build up.

Flush the plant
 
Ok thank you! Its hard watering it thoroughly like i do with all my other plants cause it is in a scrog. Also I have to buy a bunch of distilled water to flush it with? Or can i used phd tap water
 
I had lot's of weird leaf problems until I switched to R/O water. The water here is really hard and I have much nicer plants once I switched. Problems that looked like yours. I get R/O water from the supermarket.
 
Okay everybody I am going to flush my plant when she wakes up tonight with distilled water sorry I cant get RO. Do you think she will be ok?
