Yellowing leaves and Brown spots end of Week 4 flower

[Greatcobini]

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.

[Greatcobini]

I got no more room for the lights!

[OldManGrower]

Then bend and tie down the plants as best you can.

[Greatcobini]

Anyone else have an opinion?

[Rwise]

Looks like a root issue, whats the PH?

[Greatcobini]

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

[CaptainWiese91]

Way to early for the plant for losing the leaves. Look at the buds, they aren’t close to being done at all.

you have a root problem. Or a lockout

[Greatcobini]

Soo why should i do!

[Greatcobini]

Someone give me some real advice please as to what action to take

[CaptainWiese91]

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 ?

[CaptainWiese91]

Honestly I have never checked the Ph of the run off water in my 8 years of growing.
calcium can’t be absorbed by the roots if the PH is under 6,2.

[Greatcobini]

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

[CaptainWiese91]

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

[Greatcobini]

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

[Greatcobini]

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

[CaptainWiese91]

I’ve been using Ph’ed tap water for 8 years 💪🏻

[SoOrbudgal]

I got a long neck water can holds 1/2gal and my tent is 36x36
