Bottom leaf started to get spots it didn't look like neut burn so I just topped off with fresh water just in case. And it still looks like the spots are staying. 1 of my top leaves have a small spot.



Does anyone know whats causing these????

The bottom two are nothing at all to worry about,the top one,could be ph fluctuation or some kind of deficiency but as its on an old leaf at the bottom I wouldnt worry about it,just take the leaf off then feed/water as normal and see what happens.If it spreads then try adding a drop of cal mag to your feed

Actually it looks good at the new growth parts.
If you "think" the bottom leaf is more detrimental to the plant than it is doing good then cut it off. This plant is still very young and needs all the photocells it can get.
Usually the single and baby leaves will dry up and fall off. These leaves contain the inherited nutrients for the seedling.
The damaged leaves will not repair themselves.

are you familiar with fox farm nutrients?

3ML of Big Bloom
2ML of Grow Big



Does anyone know is this correct ?
Too Much?
Too Little?


Or can give me the correct ML I should be using

(Link to feeding schedule)

I know im supposed to reduce the recommended dosage so some insight on the ML would be great

I have never used foxfarm fertilizer.
As a rule of thumb I take the outdoor directions and cut it to 1/6th with any fertilizer. I know this is enough to feed them.
If I "think" it is nessesary to increase the dosage I will do it by adding slightly more each res change until I see the slight curves in the leaves which usually happens when the res is maxed out.
I do flood and drain hydro.

If you leave those leaves on that have showed signs of deficiencys how do you know if youve fixed it or not?Unless you have a great memory-not one of my strong points lol

that's what I am saying , nutrients in hydroponics is different then soil. you really need to get a brand mabe try advanced nutrients line im sure they will have a feeding table for you for hydro. just follow the chart weeks per dose of water . again if your using bloom nutrients high potassium it can lock out the calcium and make ugly spots of the leafs as well . so they could really be over fed and show sigh of defet . . your plants look alright today not all that bad . but again the thing I hate about hydro they look good this hour the next there dead . in soil it will usually give you a 1 or 4 day buffer to get it under control . from what I have read on the back of some nutrient bottles . soil get 100 % strength and hydro gets 50 % . so those small plants get what ? 25 ? lol check out advance nutrients and look at the feeding table it will inform you what direction to take . and no guess work .

cut the bottom leaf off . why ? because the plant is wasting energy trying to repair that bottom leaf that does not mean any thing so instead of the plant growing big and happy and fast. it sends a signal I need to work on fixing this leaf down on the bottom , , most of the time when you plant a seed the bottom leafs will look yellow that's normal. who cares ? the bottom of the plant will be pop corn buds any ways.
