This is my first grow. I am wondering if I am seeing the after effects of over watering or if this is light burn. Soil - FFOF w/Perlite (80/20 mix) Nutrients - None Pots - 3 Gallon, fabric Light - 300w LED (prob not really 300w but appropriate for my 2'x2'x3') Temps - 68/72, humidity 38-42%...

Hello everyone, first time on the forums and also a first time grower. Right now I am growing in a 5x5 and 4x4 grow tents using DWC. I am having problems right from the get go, going to lay out what has happened so far, hopefully someone can help me out. I have had problems with temperatures...

New here and looking for help. 2nd grow but first time seeing these spots. The light is about 15 inches from the top of the plant. I took two photos one of a leaf about 20 inches from the light and another about 36 inches away, both seem to be experiencing the same issue. I water at pH 6.5...

Hey guys I've been looking at cheap floodlights, and they are very appealing to me right now as i have a tight budget. The grow box I'm planning is about 16" in height. Now i have read about light bleaching, but I only really see it happening with powerful grow lights. The 20w LED light i'm...

I am a first time grower but jumped right into hydroponics as I have a tendency to try the coolest stuff first. I have two straight forward DWC system with two 5 gallon buckets with two air stones each. I add frozen water bottles in the morning and evening and have been monitoring the temp with...

Posting some pictures below, I will answer any further questions as needed or provide any other information that would further a diagnosis. I just want to see if someone can tell me by directly looking at the pictures first. I’m having some browning at the tips including yellowing, some what...

My girlfriend phoned me while I was at work to tell me that my plants leaves the tips of them had started to slightly curl and the edges of the leaves are going a lighter colour green, I've had them under a 600w HPS air cooled light on 24/0 (not right under it as there only small) and they've...

This little lady needs your help please. her leaves have these spots on them but the leaves are perfect other then the spots. The leaves are nice and cool to the touch, and they feel soft. They aren't curling up or down, their not ruff or deformed. they are perfect other then the spots so there...

Good Morning :) So I'm really really interested in growing something right now and find that's very cool in my spare time anyway. Sorry, my papa, he's too old to type all the words to you guys so that's why I just ready to start to this kinda thread for him. Ok, let's get started. Papa would...

I am trying to figure out if this is a potassium deficiency or light burn/heat stress. I am growing indoors, in ocean forest soil. I am 3 weeks into flowering on an auto flowering northern lights. I mainly water when the soil is dry, about 2-3 times a week. Every other watering contains fox...

So I am on my third grow (ever) and still experiencing some issues. I am using a 180w roleandro led light in a grow box that is about 10 cubic ft. Or 3.12 square ft. It is recommended the light be 18" away from the tops of the plants but it's just not possible in the size box I have. What I...

I have three 40 watt CFLs over 2 one foot tall plants. How far should I raise my lights over my plants? Thanks!

So I'm wrapping up week 3 headed into week 4 of flower and I had a few days (4 at the most) where I was maybe 5-10 minutes late on each occasion opening the tent and I had some leaf and bud burn result. Sick about this but nothing I could do to get home any faster. Just wondering how much damage...

Hi guys. I really need your help to save my grow. I've been battling these issues for a while now and it's hard to pinpoint what's wrong here because I think it could be a few different possibilities. Nute lockout, underfeeding, lack of CO2, or light burn. But I really need the money from these...

Issue #1 is her size. I have tied her down but still she rises! I am seeing stretch and she's only been in flower 2 weeks. When will she focus on buds and stop growing? Can I top her topmost tops? or could that stress cause her to herm? Issue #2 is she is dropping leaves. She has some leaves...

Doing a little LONG overdue pruning I came across this little gem and thought it might be an interesting game for the LED cognoscenti. Below you'll see an interesting bleach/burn pattern of my LED situation. Which LED in what configuration caused that burn? Take a guess or submit your own...

I'm 3 weeks into flowering with really nice tops from fimming and having my 600w super HPS hanging horizontally. I've now decided to hang the same light in the middle of my four 3 gal pots vertically. It's been hanging vertically for 3 days now with the plants less than 6" away. The light looks...
