Starting to look lighter green, stressy hanging leaves.

Hi fellow growers,

can you please have a look, I used the 2ml per liter on the biobizz light mix soil and 0.5 ml per liter on the biobizz allmix with wormcastings.
I have one plant in MILLS lightmix, I added some batguano and wormcastings myself on this one. The only one that looks healthy.
But grows really slow.
I am confused on what to do, its a shame I dont want to screw it up, they are 2 months old clones with GG genetics. They are in 50 liter pots, temps underneath the pots is 20 celcius, ambient is 24 celcius.
I used organic ferts BAC, bonemeal, molasses is inside. They are in VEG , I want to change to FLOWER but I need to adress this health problem first I think.
Should I change to hydro feed to save this grow?
Thank you, thank you, SFX

I believe you could be either having a magnesium or maybe a sulphur deficiency. I have them periodically using biobizz depending on strain.
What I normally do is spray twice in a one week period with a solution of Epsom salts in water.
Epsom salts are magnesium sulphate so they cover both deficiencies brilliantly.
You can also add the Epsom salts to your feed as a root drench but I found the foliar application to have a much quicker positive effect.

Awesome, yes so I wasnt adding epsom for nothing in the 90's, I just started again after 20 years of maybe 1 or 2 grows. Thank You!!! I just added CAL/Mag from ATAMI, I wil go and get me some Epsom again, I used to add soemtimes Maerl seeweed chalk, shall I start doing everything like I used to do it? One thing, there is not enough CAL/MAG in the water? I dont use RO water, I want to start with that soon, if I can get a decent harvest again like I used to. At the moment I feel like I lost my touch. Thanks for every tip and suggestion. Lets keep this grow alive.!!

I gave the worst looking lady, with drooping leaves, yellow, stressed besides A dose of CAL/MAG ( it said 0.1 ml to 1ml per liter, I did 0.5 l per liter) I gave her water with 150 grams of wormcastings and 150 grams of batguano, fingers crossed!

Looking at pictures of Mg deficiency it starts from the bottom, but in my case
the bottom leaves are healthy, I do have purple stems though, that rhymes with Mg def.
Unsure what theproblem could be, lime maybe? Lime acts as a buffer if I remember right.

Yellow at top of the plants is often sulphur deficiency. I said magnesium because I noticed the yellowish leaves have green veins still.
Epsom will cover both problems.
Ive never used calmag, my tap water has enough calcium in it.

Thank you, yes could be sulphur, I will buy some Epsom. I looked it up. Or Calcium.

I gave them 4 gr epsomsalt per liter water, as foliar spray, is that too much too litlle or ok?
When should I spray them again? I week, or tomorrow.

Also I washed off the epsom after they dried up, with clean waterspray, Is this neccesary?

I only put a level teaspoon in a litre of water, I've never weighed it. Shouldn't need to rinse off but it won't harm.
I would give it 3 days then spray again. That's all it will need. If it is sulphur you should notice greening up again within a week.
