Hi all. Hope someone can help me. I'm new and this is my first grow. Trying to start off simple and work my way up.

Grow medium (soil, coco, hydro):Soil- Fox Farm Ocean Forest

Strain: Gelato Fem

PH of your nutrient solution ( Feed):Don’t do

PH of the run off, or Reservoir: Don’t do

EC/ PPM of Nutrient Solution before Feeding:Don’t do

EC/ PPM of the run off, or Reservoir: Don’t do

Nutrients Brand, and how many ML per litre of which foods. Fox Farm Big Bloom, 5mL removed link , Fox Farm Tiger Bloom 1.25mL removed link . I feed 1 Liter per plant once a week.

Grow room temps lights on/ lights off ( On/ Off): 23C on, 21C off.

Grow room humidity lights on/ lights off (On/ Off) On 62, off 75

Res temps if hydro:n/a

Lighting type and wattage (hps, led, cfl): 2, 1500 watt led

Extraction (Size of Extractor, and where you draw and exhaust air from):

10 cm fan drawing from basement (where my grow room is) exhausted outdoors. Noticed this the other day. Thought it got too hot in the room. Thought it might have gotten to 27C. I have 4 plants total and this is the only one doing it. Thanks in advance. -Jeff

Can we get a pic of that with the lights off mate? 

Hows your watering schedule too? Leaving the medium to dry out somewhat before watering again?

I water a couple times a week. I was afraid they were drying out too much. They're almost into 4th week of bloom and seem to be really drinking a lot.

The rest of the plants as far as I can see look ok, and the issue seems minor. They are a good dark green healthy colour. So Id be more inclinded to syay this was a pH issue more than a nutrient problem. 

It would be a good idea to invest in a pH meter so you can keep track of what the ph is your feeds. Over time, the feed will change the pH of the soil. If the pH isnt in the right range, the plant wont eat properly. 

Can you get a pH meter online or in a grow shop near you?

@macky I can get one online. With all of this virus crap going on I haven't been going anywhere. Do you have any recommendations? Like I said, I gotta go slow with buying stuff. Hope to build up my arsenal over time. Should I trim damaged leaves off?

@jeffro No just leave the leaves mate, they still work and they will still do their job Smile

The best one on a budget is essentials ph meter. If you can afford a blue lab one even better. But essentials will be fine to Smile

@ctlc993 Yes. Uppermost leaves. I thought maybe the light burnt them but it wasn't that close. I raised it a bit just in case.
