Nute burn?
Growfunstarted grow question 3 years ago
PK issue maybe.Their in superish soil and I have been feeding them every other watering with tiger bloom. Blue cheese and I have read it likes lots of supplements. I laid off 2 waterings ago and it happened to a few more leafs. How long for Nute excess to go away on its own?

I found Tiger Bloom to be way too potent at recommended dosage. My girls took miracle grow like champs at full strength. But as soon as I introduced Tiger Bloom during flowering all hell broke loose. Burnt tips and fox tailing galore. Use Tiger Bloom at 1/2 to 1/3 strength at first and adjust from there. But it sounds like you’ve got to flush them a bit before you feed anymore. Gonna get salt buildup. Get some runoff going next watering to clean out the roots a little and you should be good.

Hi there, IMO those rusty spots could be either Calcium lock out or deficiency.Give a slight touch of cal-mag couldn't be wrong. Before you do anything, make sure your water pH, ppm(EC) and run off are in corrected range.If you are growing in soil, keep your pH around 6.0~6.5 for both of your water and run off.Also in soil,the less nutrient the better to prevent lockout.Happy Growing... ✌️

It will continue until your soil has the proper EC and the plant has used up any residual nutes it took up. This could take a few days or a couple weeks depending on how hot the soil is and how much water you're giving. Once it stops spreading, you'll know you're good. The affected leaves will likely never regain their healthy green look. Get it right, remove all affected leaves, then keep an eye on it to make sure the problem doesn't happen again.
Test the pH in your runoff as well. Hot soil often goes hand-in-hand with acidic soil.

Leaves darkening after flipping to flowering nutes. D55 Auto.She seems to have gotten a much darker green over the last week or so and leaves have begun to take on a different feel. Assume this is just part of entering full flower, but given it seemed to coincide with switching to flower nutes I just wanted to make sure its not a toxicity.

From previous post just some more infon on what I feed and how, on a 12So I use 5 ML per gallon of fox farm Grow Big Liquid Plant Food, And 5 ML Per Gallon Of Fox Farm Buds And Blooms Fertilizer. I'm barely staring to Introduce Cal-Mag so I don't think the Cal-Mag is causing the issue, I water every 2-3 Days. Temp is Right Around 80 during the day 7

Small marks on leaves a concern?I noticed only a couple leaves out of a 4x4 gg4 grow show weird marks. Just wondering if it's cause for concern since it's my first grow. Otherwise they appear to be perfectly healthy, growing great and praying going on 4 weeks into flower.

I noticed that the lower 2 leaves are yellowing and I think that are a little crispy. I topped the plant at the beginning of the week ago and I removed the first pair of leaves three days later ( yesterday).
Do you think is this a problem? What can I do? Thank you. Peace

Is this pH related?Hello, mates!
Anyone knows what this could be? Searching I found that it could be pH related. I use pH controller from ferts (pH perfect from advanced nutrients) since the beginning, so I think it's odd that it could be a pH issue.
p.s. 3.5 weeks of flowering
Thanks 🙏 🙏

Which deficiency?So I've asked before if it was a magnesium deficiency on the GC and got confirmation based on the early pic, but now I'm starting to wonder if it is? Buds don't seem to fatten up either. Maybe calcium or potassium? Lights too strong? Overfed? Shouldn't have given Vega just flowerWeek 8

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Scalloping/Wavy Bottom Leaves on LSD Seedling. First Indoor Grow.Not so much a problem but being this is my first indoor grow i'm curious as to why my first set of leaves that grew off my LSD Seedling have gone scallopy/wavy, yet the rest look fine? Should i worry or is this just normal.
