Okay, good to know It’s my first indoor grow so I’m easily triggered lol. Thanks for having a look

The new growth has always been a slightly lighter shade of green but it looks a like it getting lighter and more noticeable. I’ve been feeding 1/4 strength FF Grow Big and regular strength caMg+ with every watering. Is this normal or should I boost the nutes? I’m nervous to burn them as I just...

I’ve got 6 plants that I was planning on topping. I was originally going to top them a couple of weeks ago but was having some issues that I needed to figure out before I topped them because I didn’t want to cause them too much additional stress. Currently on day 40 from seed and have around...

:clap: Looking great!

Heavy dose of General Hydroponics CaMg+ should solve it.

The plants have all recovered. thanks for everyone who helped out in this thread - I’m shocked how fast these plants have come back and are thriving again.

I haven’t fed anything except cal mag. If it’s “loaded up” it’s from the soil... I got a new ph pen today so I will compare the 2 readings and post back.

I think that may have been it. Not watered enough with the combination of heat up to 30 made them soak up more nutes in the soil which caused some of the burning.

Yes that’s what I heard the Master Kush was flawless until just under three weeks. They are now 4 weeks old. The white Siberian I had issues with since they were only 2 weeks old. I’m using a Rozway digital ph meter I got off amazon for $25 - so it’s definitely not top quality. It’s brand new so...

Sorry I don’t mean my circulation fan, the inline fan that pulls air through the carbon filter and then exhausts out the air cooled hood.

Now that I have my air-cooled hood I have my carbon filter and 6"inline fan hooked up to it to create the passive airflow with negative pressure. Should I still run my fan 24/7 to keep the air circulating or have it sync up when the light turns off to also turn off? Will this mess up the bulb if...

Picked up an air cooled hood today and happy to say temps are under control around 23-24 degrees. Huge difference the air cooled hood makes- I wish I got this way sooner.

I’ve been using a digital ph meter and I believe it is calibrated. I have some buffer solution to re-calibrate. Is it possible I just didn’t start feeding them nutes in time? I was reading a journal of someone also growing in FFOF and they noticed similar symptoms around day 19 and started...

I haven’t fed anything. Only 6.0-6.5 ph’d water going in. My water here is 7.5-8.0 out of the tap.

After doing a ton of more reading I just flushed one of my plants, my water here has a ph of around 7.10 and the water runoff was 4.5! This whole time I've just been phing the water to 6.0 - 6.5 and then watering and wasn't testing the run-off. Should I flush everything?

Running in Fox Farm Ocean Forest. Watering only 6.5 PH'd water and had one feeding of cal mg+ when issues started happening last week. Humidity is at 45% in the tent right now, with the temp at 25 - I lowered the bulb ballest to 400W so I'm seeing if the temps still get above 26. It fluctuates...

Great! Thanks for your comment. I will reduce to 400W and see if that helps. Okay, I will pick up some Epson Salts and give it a shot. Thanks for your comment.

Ah that could be - My humidity is around 50%. My ballast can switch down to 400 or 250W - Can I still have my 600W bulb in there and set it to 400W without any issues? Would this reduce the light output and heat? Sorry for my ignorance - this is my first indoor grow.

Yeah, I have a fan for circulation and it’s still getting really hot. Here is a pic of the setup. Everything I’ve read says that up to 30 degrees is okay but I’m having some issues - it could be light burn? My plants

Update: I tried supplementing some Cal Mag and nothing, The white widow has gotten worse and the Master Kush is now showing the same signs. Please help! I noticed that now with the warmer weather my basement is getting warmer so the inside of the tent has seen temps close to 28.5 degrees. Is it...
