Burnt yellow edges autoflower? Too hot?
martonxstarted grow question 4 years ago
Some girls show some issue, like burnt yellow edges on the leaves. I have still a little hot hot temperature (over 30C), it's this reason? Or some shortage or surplus? Should I worry? Start of 8th week. 3th week of flower. Thx.

Hi there, I think your plants are suffering from light burn.Your light distance to plant is too close and your temp is too high.The leaves which are exposed to light longer than other leaves will show those symptoms.Raise your light until you don’t feel hot and lower your temperature by adding more ventilation or portable air cooler.It will be the best action to take now.Later on check for water and run off and adjust your nutrient dosage if necessary.Happy Growing... ✌️

Seems more like light stress than heat stress to me. Your lamp is too close, manufacturers recommendation is 12~18'' above canopy for flowering and you are at 10" according to your diary so try to raise it abit, or alot until they are recovered. If you cant raise it up then dim it down

If you're having problems with the temp this is the problem. The temp is making the plant intake the nutrients too fast, so it's causing a nutrient burn. Fix the heat issue and things should start clearing up.

Why are there soon many brown spots all of a sudden in WK 7?I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great.

Nutrient burn?The leaves on my two plants are starting to show signs of burning. Is this nutrient burn? I have no added nutrients yet but I am using Happy Frog soil. I’ve raised my lights from 24 to 28” in case it’s light burn. What are your thoughts and recommendations?Week 2

Is the browning caused by nutrient burn or symptoms of something else? I had previously backed off, but want to know if I'm missing something. Most of the stems are red for leaves as well as petrioles. My runoff is around 900 each time @6.1. Only one plant of 2 has this.Week 4

Leaf damage and flower analysisAsking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Nutrient burn?I believe I overfertilized this week. I am using a four bucket DWS system with Reservoir bucket. This is the last week of my veg and I might’ve been heavy handed with the fertilizer. At one point my solution was 1844 ppm. I usually run itbetween 8 to 1200 ppm. I delutedd the solution in half. I didn’t have time to change it all because the lights are going out. Do you think this is nutrient burn? Thanks

What am I facing? Plant is getting worst everyday, and I can't find the reason why. Thought it was a calmag def, but now I don't really now.When I switched to flower, I started watching some rusty spots on the leaves of the gelato.
After doing some research, I thought I was facing a calmag deficiency, and starting adding some calmag.
Plant is getting worst, I flushed the roots and water between 5.8 and 6 as canna ask

Browning/Yellowing tipsBoth of my GSC's are suffering from browning/yellowing tips? will they recover? is this because of heat stress, nitrogen deficiency or over-watering? or something else?
The second plant seems to have the most browning/yellowing fan leaf tips and first plant had little to none.
