What's wrong with my plant? Too much fertilizer in the soil?

No one should be saying that a pH of 7.8 is too low. Anyone who claims that will get flamed. Your pH for soil should be 6.0-6.5, that is the accepted value, period.

It takes time for the plants to visually respond. Applying a foliar spray will give quicker results however.

So to answer your questions, I'd do both a foliar spray and a flush w 1/2 strength nutes.

For the foliar, I use a product w plant or fish protein hydrolysate and sea weed aka ascophyllum nodosum. I use floralicious plus by GH.

And the flush should be with nutes that have all macros and mircos in proper proportions. I use GH three part.


Thanks for the reply

Some have told me to use that splashing and washing plants Epsom salt? Is this a good idea or not? But I can use Plangron PHYT amine? If I understand you to mix 1/2 water mixture fertilizer (nutrients for growth) and wash plants? Then sprayed the leaves?

First, Epsom salts is magnesium sulfate (MgSO4), which mainly provides Mg to your plant. While not harmful, its not usually necessary when using a complete nute. But the 1/2 strength "splash" should work. Assuming you mean splash = flush. I am not familiar w those nutes, so just ensure they contain all needed macro (N,P,K) and micro (Mg, S, Ca, Fe Mn, Cu, Zn, Mo, B, Cl). The flush is to purge all nutes which may be out of balance and replace w the new mixture. Return to normal feeding when next watering is needed.

One note, Mg, Ca, and S are actually secondary nutes meaning they are needed in levels greater than the rest of the micros, but slightly less than N,P,K.

This morning I sprayed with a mixture of epsom salt the leaves, the plants look better 12 hours (more dark green leaves)...I saw that the soil is dry now and have watered. Should now I water the soil or wash? I'm a little confused, the one telling me to wash with a mixture of epsom salt (I can not use ph down). Others say we should do half mixture of nutrients (fertilizers grow and can I use ph down) and wash.

The light absorbing "head" of chlorophyll has as its central atom Mg, which is an element found in epsom salts. This molecule is called the Porphyrin ring. this would explain the quick greener effect. Mg deficiencies can be caused by pH issues or perhaps your nutes don't contain sufficient quantities. Since you already supplied Mg via a foliar spray, I would lean towards watering with pH adjusted nutes. Do they list the elements by % on the bottle? That might help you use the right stuff in right amounts.

Thanks for the tips! They are useful! Nowhere can I find a list of nutrients for Ata Terra leaves:( I will order new fertilizers from today BioThrive grow, Bio Essential and BioThrive bloom! Friends say that the fertilizers from the GH top quality!

Not sure about how they name GH in your country, but I'm assuming your going with the GH organic line? I used the GH ogranics line on a plant in sunshine #4 and it did as good as the GH flora (3 part- non organic).

At a minimum, you must add the CaMg+ w the BioThrive. And it is recommended to buy the whole line. I bought a "GO pack" that came w the whole line up. And be sure to add Sub-M and Sub-B if going organic or make tea so you have the bennies to help the plant absorb the organic nutrients.

Personally, I found the GH flora 3-part (non organic) to be the best bang for the buck.

GH- General Hydroponics :) Yes, organic line. In our country do not have all products from the GH :/ Now I have to just BioThrive grow, Bio Essential and BioThrive bloom. I also CalMag but not from the producer GH!

Of plant did not repair anything: (

Tomorrow I water the new plants because the soil is dry. But now fertilize the soil with fertilizers and CalMag?

Yeah, nutes + CaMg and be sure to check pH after adding nutes. GH Biothrive lowered my pH to 5.6- 5.8 w/o any pH down. Don't worry about the low pH w this product let it be. But if above 6.5 you need to lower. I do 6.0 in coco.
Don't be too concerned about older affected leaves, concern yourself w new growth.

Thank you! Then I mixed fertilizer (BioThrive grow 15ml/10l + Bio Essential 1,5ml/1L) + CalMag.

How many times a week should be fertilized with bio fertilizer? The Atami fertilizers I 1x a week fertilizer and watered 3 times with water. I will report what the situation will

I need your help :) For my plants I have one problem, the leaves emerge a kind of spots and the lower leaves fall off slowly.

Seeds- Jack Herrer

Soil grow (Scrog)

PH 6.1-6-3

EC 1.4 ( 3:1 Tap water/Ro water used)

21. Flowering

Sse of fertilizer FloraNova Bloom 10ml/10L (670ppm, 0.5) + Bio Bloom (2ml/10l) + Mineral magic ( 2g/1l).

Fertilizers 1x a week and 2x a week infused with water only. Always regulates the pH to 6.1-6.3

I did not find any mites in soil or something

Don't worry too much. The lower leaves are covering each other and causing condensation and low air flow in the thick growth will cause the spots and some to fall off. I usually clean up some of the bottom leaves to increase air flow once in flower.

Thank you for your answer....I will increase the flow of air in my room! I will add one fan for air circulation to the lower leaves, I hope you will be fine..

Again I need your help

Soil grow (Scrog)

PH 6.1-6-3

EC 1.6 ( 3:1 Tap water/Ro water used)

Fertilizer FloraNova Bloom 12ml/10L + Bio Bloom (2ml/10l) + Mineral magic ( 3g/1l) = Total 810ppm

35. Flowering

Is it possible to overfeed? Fertilizers 1x a week and 2x a week infused with water only.

They may be under fed, or not getting enough Ca and Mg since you are using RO. What's in mineral magic? With RO you need to prep water with Ca & Mg then add nutes. That yellowing leaf probably won't recover but to keep it from spreading I suggest you make sure there is Ca & Mg in that mineral magic and increase the flora nova to about 20-25ml/10l, or 1.5 to 2 tsp/gal. I would imaging the ppm should be around 1100-1200.

I use a 3:1 ratio (tap water and RO water), I never use only RO water, always mix it with tap water.

Mineral Magic contains: Silicate (SiO4) 59.6%, Iron (Fe) 4.7%, Magnesium (Mg) 2.5%, Sulfur (S) 2.0% + 65 other salts.

FloraNova Bloom NPK 4-8-7, Calcium(Ca) 4%, Magnesium 2% , Sulfur(S) 2% , Iron (Fe) 0,1%

A is not sufficient Ca and Mg?

At the Green House Seed-Jack Herer says it's best to use 1.8EC ( 900ppm ((factor 0.5). Is not it a little too 1100ppm (2.2EC)?

@medicalmj I took your advice and dvignal nutrients (18ml/10L) to 980ppm (1.9EC). Now I do not use more RO water. Unfortunately, the situation has not improved but worsened :/

45. Day flowering

Temp. room 22-26°C
Ventilation works 24/7
PH - 6.3

I guess it would be overfeed? Whether the problem is something else?

Looks like a Calcium issue to me, but it's hard to tell what is going on (deficiency, pH-problem or overfeeding) because I really don't know anything about the stuff you are using. You might want to water with pH'ed RO only for a few days and see if it gets worse, and if it does feed extra Ca. Or wait if someone else has a better suggestion :)
