potassium

Hi guys I just went and checked my plants and one of them had these leaves on it, I think it might be a potassium issue, it's in a rdwc setup with cyco nutrients the temps range from 16°c lights off to 23-26°c lights on under 1200w of HPS with an ec of 1.6 and a ph of 6.1, I noticed a bit of...

I am trying to figure out if this is a potassium deficiency or light burn/heat stress. I am growing indoors, in ocean forest soil. I am 3 weeks into flowering on an auto flowering northern lights. I mainly water when the soil is dry, about 2-3 times a week. Every other watering contains fox...

Sup guys. Going in on week 6 of flower and half my plants are going through some problems. Some leaves dont have burns on the edges. Some start in the middle of the leaf. And leaves effected are on top and middle of plant. Not the bottom ones. I decided to go with subcool super soil...

Hello people, I'm a first time grower and I was hoping for some advice with these punks. The last 2 waters I have only used PHd water with CalMag, as I was advised I had over fed with nutes and had a calcium defiency when I last post. This seemed to work initially, however they are now flexing...

I'm not too sure which one it is. I'm assuming it's all of them. 5th weeks in hydro. Sour Diesel. 300W LED (140 true w). 5 gallon bucket. Hydro with clay pebbles. I can't figure it out if it is magnesium problem due to the pictures and or potassium problem. There seems to be a lot of problems...

I was at a pawn shop and stumbled across a growlight with reflector, digital balast, fixture and 6500k full spec. MH 600watt. This thing scares the shit outta me. At first it was making this holow matalic clank, but once the lamp warmed up it smeed to just do its thing. just the fan on the...

Hey everyone. Just wondering what some good sources of Potassium are for your plants. Are there any home-made remediess, or just to use a different fertilizer? I've been using Neptune's Harvest Fish Fertilizer which has about 2% Nitrogen, 4% Phosphate, and 1% Soluble Potash (K2O). It's ratio is...

Hello everyone, started a few weeks ago, going worst and worst. I tried to lower the nutes, went worst; tried to feed them more then, not much of a change yet. The soil PH is 7,1, water is always 6,7. I'm using Dynamics N3 soil. Temp 20° - 29° C, RH 40 - 50%. The plants keep turning her stems...

I have an obvious nutrient deficiency but i cant figure it out, i believe it is sulfur or potassium but i would love any opinions or feed back on what you think it is and what i should do about it!!

Ive done enough reading and my head hurts. Ive compared other products to mine etc but Id like an opinion from other coco growers on my nutrient ratios.. Specifically K:CA:MG (my understanding is this ratio should be 4:2:1) I run: Botanicare CNS17 @ 17ml/Gal, Silica @ 5 ml/Gal, Fulvex @...

Someone from another site said it looked like calcium but I have been using calmag at full strength and ff nutes not at full strength, big bloom, grow big, tiger bloom Been giving less grow big since it started budding and it should have 3-4 weeks left I thought it might be potassium but it...
