Haven't quite been to full strength. Around 3/4 is what I've got up to. I didn't feed any grow big this time. Just cal mag and big bloom. In ocean forest. Ph 6.5 or 6.6. Temps low 70s with light on 65 with it off. 7 weeks old. Just topped. My other one isn't doing it really. Just one leaf has a spot or 2. But it's in happy frog. It's hard to see the spots with my hps onYou didnt put much info in and no pics would guess your over feeding. If your using full str nuts under a 400w light. In flower its more likley a mag problem than cal but again no pics. Cal mag is chock full of nitrogen also.
I never said I was using house and gardens.. Somebody else may have. I know I am using all fox farm products. But cool I watered with a good amount of cal mag so hopefully that will stop it.Big bloom and grow big are fox farm products. You said house and gardens. That would be soil a and soil b. Not that that really matters. Yes looks like a mag deficiency. It isnt your fault the over feeding. The nutrient companies write there directions with the assumption your under 1000w. Many dont know there is a direct relation between the amount of light and nutrient use. Plants unser 400W light is all ready using less than half the nutes as one under a 1000w.
Yep different person sryI’m in week 7 with a plant that is totally fried. All the sugar leaves dried up. Barely any fan leaves left. The flower already ‘feels’ and looks dried out.
I’m cluelessness as to where I fucked up. I’ve significantly reduced nutrient levels in attempts to lower PPMs, so I really don’t think it’s an ‘overfeeding’ issue. I think it’s a late flower nutrient issue (House and Garden), and my inability to properly dial it in.
No problem. Thanks for identifying the mag deficiency. Hope it stops it from getting any worseYep different person sry

I’m using House and Garden, and it’s kicking my ass from week 6 to finish.I never said I was using house and gardens.. Somebody else may have. I know I am using all fox farm products. But cool I watered with a good amount of cal mag so hopefully that will stop it.
Yup, that is what I’ve been using for several grows now.I like hng. Old reliable company. They have one of the best root stimulaters on the market. Roots Excelerater Gold
Topping the plant might stress the plant a little but it would not cause the brown spots. The yellowing between the veins of the leaves is likely magnesium deficiency. The brown necrotic spots are possibly calcium IDK.Thanks man. I think I'm running into a calcium issue right now. Just noticed it on a few fan leaves. So Just watered with 7.5 ml of cal mag and some big bloom. Been keeping ph at 6.5 or 6.6. I just put them under my hps yesterday. I had it under 400 mh at about 15 in above tops of plants. And switched to hps yesterday and had it about the same height above them cause I'm about to start flowering once it recovers from the topping I did. Could that cause some leaves to have goldish brown spots on them?
EDIT: Lol didn't realize you directed that towards him. Thought it was too me haha sorry
I watered with 7.5 ml cal mag a gallon and 11 ml big bloom last night. Do you think I need to flush my soil? Some of my leaves are looking bad.Topping the plant might stress the plant a little but it would not cause the brown spots.

My last two grows in soil I had 3 noticeable deficiencies. Nitrogen, magnesium and calcium. Same three are showing up this time. I can show pics of the mag and nitrogen def on these plants. The calcium def was stopped quickly and would be hard to capture in a picture. I can find lots of old pics of calcium deficiency but they may not appear on my plants the same as yours.
To Daveindiego. Week 4 - 5 are very common times for a grower to run into problems. Yesterday was 3 weeks from flip for me. It is a crucial time for me to keep an eye on my plants to see if I am going to run into issues. I still have between 8 - 10 weeks to go before harvest.
Everybody succeeds in different ways.
This is what I do at this time when I have a deficiency. A year from now I might be doing things differently.
For calcium deficiency I use cal/mag+
For magnesium deficiency I use Epsom salt.
For nitrogen I use blood meal (not recommended by some members) and just bought Alaska fish fertilizer to try today. Hope it does not stink to much
It is important to note that many growers who run into a calcium deficiency in soil are getting it from watering to often, not letting the soil dry out causing a nutrient lock out. When someone does that a common time for the calcium deficiency (lockout) to show up is in the 3rd or 4th week of flowering.
Good Luck!
Sorry, I am not qualified to answer that. I can only say I will not flush my soil. I have reused it several grows and needed to leach it of a build up but that is different from a flush.I watered with 7.5 ml cal mag a gallon and 11 ml big bloom last night.

I was just fixing to begin flowering to. I transplanted Thursday night into final pots and everything looked fine. Put my hps in Saturday to let them get used to it and then Sunday I noticed a bunch if leaves with spots and some edges curling up. They looked really good up until yesterday. I think it's a mag deficiency but I've been using cal mag every watering but not full strength. I don't know what to do.Sorry, I am not qualified to answer that.

That's why I say to look for Ca/Mg based in Calcium Carbonate and not Cal Nitrate.....You didnt put much info in and no pics would guess your over feeding. If your using full str nuts under a 400w light. In flower its more likley a mag problem than cal but again no pics. Cal mag is chock full of nitrogen also.
