Help - sick plant

Thanks, no it seems immobile as mostly affecting newer. I think it’s a mix of light burn and Potassium deficiency. I’m following the schedule since week 2 of flower.i don’t have a ph pen as thought the ‘Ph perfect’ adv nutes keep the ph correct but I’ve ordered one. It’s a 10Ltr pot. Thanks

I used to use sensi ph but it wasnt ph perfect so i went flora 3 part never a issue again. If your nutes are good no such thing as a nute deficiency. Ive never had a nute defi just a ph deficiency. Honestly only thing that matters with pot is ph and nutes. If u follow nute program (but half reccomended) and ph ur watering no issue ever. Ph is key man.

I'd guess over fertilizing. Try plain water every other day or every third day. Maybe throw some Recharge, Great White or other beneficials in the soil to help break down any salts. Water until run off and PH the run off.

Shit she’s still progressively getting worse after raising the lights and flushing

If that damage was due to light intensity you’d have taco’ing of the leaves. This looks to me to be more of a nitrogen toxicity. You said you flushed with 1
liter ? Unless you have a 0.5 liter pot then that’s not nearly enough. Buy yourself some unsulphured blackstrap molasses to add to your water . This will flush out any salt build up and improve the microbial life in your soil. If you are using a 1 gallon pot, flush with 1 gallon, then another 2 gallons about 10minutes later . Make sure to PH your water to about 6.5 If you can !

Go the natural route and buy some blackstrap molasses and some kelp. Much more forgiving !

@Breathm judging on pics alone, a little extra bump in the (K) will probably help your issue

Looks to me more like a magnesium deficiency. I'd add some epsom salts to your water, like 1/2 teaspoon per gallon....A foliar spray would help too.

Have you been using calmag?

After further review of the pics , and waking and baking, I agree. Magnesium deficiency, the leaves are starting to yellow from the sides not the tips in most off them . I still think there is a nitrogen toxicity though due to the deep green colors on some of the leaves , and tip burn. I’d get some kelp and foliar spray after a flush.

Thanks a lot guys. Still slowly getting worse I think. What’s the best way to increase the K then, kelp and molasses? Thanks again

I dont personally believe its a Mg issue. You had mentioned using micro/grow/bloom in a previous post so Im assuming its GH 3 part? Mix up some of the bloom nutes (light pink 0-5-4) and add accordingly. This should bump up your P & K while the plants demand is higher in weeks 4+ of flower and hopefully resolve your issue. Treat it like soup and add sparingly. Give it a couple days and assess. You can always add more if needed.

Thanks HydroRed much appreciated. It’s Advanced Nutrients ‘ph perfect’ 3 part. Great I’ll try that then, but does it mean only give bloom and water, ie no Grow or Micro? Thanks very much

judging by the burnt tips on the leaves, its already a "hot" mix of nutrients. I'd dial back on any other feed except for bloom to try and tackle the issues of the serrations of the leaves going like they are. Can you supply a pic of the plants with the lights off, or in natural lighting? Everything looks really artificial green in the pics and its hard to gauge their needs. I dont know what your previous feed schedule was, or if the soil you used had nutrients in it already, and you are feeding on top of that etc. Lots of variable here, but just gauging on what I can see in the pics, they need a boost in P/K. No Mg/Cal or any N based ferts.

You’re a gentleman and a scholar Sir, I’ll give that a whirl and report back, thanks again man

I can’t get pics with natural light but will try get a clearer one

HOLY SHIT I did what you suggested, 4ml of bloom (1-3-4) this morning and 8 hours later she’s showing really much better for the first time in weeks, I check on her a couple of times a day and today she’s recovering by the hour. Fingers crossed I think you saved my plant man..

 

[Breathm]

Definitely looking a lot better, colour returned to leaves and the buds are flourishing again after just 24 hours. Many thanks HydroRed!

What’s step 2 you tease

Glad to here,most people are so scared about over watering.All they need is food.After a month of growth and feeding build up starts.No matter what kind of soil its really just peat after a month.So the answer is feed it like peat,feed to runoff just like coco.You can plain water between feedings but make sure you get the runoff when you feed.

People would be better off just starting with peat rather then FF or some other cheap soil.Its cheaper and easier.Treat it like coco and no problems .

Thanks Mike I’ll follow that approach, more less often maybe
