First time grover needs help with deficiencies

otkafa · Nov 11, 2013

Hi,

I have 3 Critical + , 3 Original Amnesia, 3 Mobydick they are all autoflowers by dinafem. I am at day 40 and I have some deficiencies that I could not fix. I am using biobizz organic nutrients feed-water with molasses-feed cycle. I have started feeding at beginning of 4th week and increased the nutes by slowly My feed cycle nutrition solution now at day 40 is 1ml/1liter Fish Mix, 2ml/1liter Bloom, 3ml/1liter Algamic and next feeding water with 15ml/4liter organic molasses unsulphured, I water every 2-3 days. I guess that is cal mag deficiency but it might be nitrogen or something else I need your opinion please. I am using Biobizz Algamic to fix it since I can not get the cal mag. What do you recommend? Thanks.

I'd say you've got a sulphur deficiency pal

You sure about that? Sulfur deficiency is hard to tell from nitrogen. The main clue of sulfur deficiency is that NEW LEAVES are affected first. Looks to me like it's happening on the lower, older leaves.

Mr Samsung · Nov 11, 2013

The only thing that swung me towards sulphur was your leafs look slightly claw like where as in an nitrogen deficiency the leaf remains stiff and flat untill falling off.

if you feel deferent pal go with your Instinct, I'm just trying to help you to the best of my knowledge

good look and if I can help you with anything els let me know

Thats a nitrogen deficiency. So called bloom nutes rarely contain enough to properly maintain a plants leaves. Your plants need more N and drop the molasses.

Jack Harer · Nov 11, 2013

They definitely appear chlorotic and look like they lack N, but you also have a cal/mag issue there as well. If you can't get cal/mag, try Epsom salts at 1 tsp/gal dilution. Are you using RO or distilled water? If so, STOP!! The plants NEED the dissolved solids in tap water, RO leads to cal/mag problems unless you supplement the minerals found in tap water, and why try to supplement them when they are freely avail and in the right ratios? Chlorine and Chloramine aren't nearly as bad for your soil as people say. I had probs when i first started out using RO/Distilled water, but have had no probs whatsoever since reverting to tap. I no longer even let it set overnight or bubble it. Straight outta the faucet!

buy some calmag or something of the sorts

I use cal mag on every feed. Recently started adding a teaspoon of epsom salts springled over the surface too.

Jack Harer · Nov 11, 2013

I have found that many Sats or Sat dom strains devour Ca and Mg, especially from mid flower on. I also supplement cal/mag when I flip my girls.

welshwizzard · Nov 11, 2013

Keeps those leaves nice and dark! They LOVE cal-mag once flipped!

otkafa · Nov 11, 2013

I use tap water, I leave the water in the bucket for 2 days to breathe.

more support please

welshwizzard · Nov 13, 2013

You need cal mag and a ph pen to ph water water to the correct ph for your growing medium.

They are essentials that dont cost a lot, Cal mag, Ph Pen, Ph down.

I fed the 3 Critical yesterday with 1.5ml/1liter fish mix, 2ml/1liter bio bloom, 3ml/1liter Algamic, 10gr/4liter Epsom salt and I always adjust my water ph 6.2-6.5 after mixed with nutrition. I use 3gallon/11liter pots, I water 3-4 liter every 3 days. I have cleaned most of the yellow leaves, here are the updated photos;

Jack Harer · Nov 13, 2013

Have you checked the pH of the soil itself? You see how the chlorosis started at the lower leaves? That is a classic case of nitrogen deficiency if ever i saw one along with a good start on a Ca/Mg def. I don't know from adam what 1ml/1liter of fish emulsion will give you in the way of avail nitrogen, but obviously it aint getting it. You aren't baking a cake here. 1 ml of this, and 2 tsp of that isn't much in the way of a recipe for success unless you are in hydro doing what I call the "baking brownies" formula for growers made easy. This is simple botany/biology. N-P-K baby, and the other 10 essentials are what gets it, not some concocted formula someone in some lab came up with.

Alexander Supertramp · Nov 14, 2013

Yep Jack NPK at a ratio of 3-1-2 and Ca and Mg at a 3-1 ratio along with the other 11 essentials from start to finish will treat a plant and grower right. Dyna Grow 9-3-6 has all a plant needs in a single bottle. Add some dolomite lime to your medium prior to the grow and your all set.

Updated pictures from Amnesia what is wrong with them? Overfertilized?

welshwizzard · Nov 15, 2013

Looks a bit Cal Mag deficient to me. Thats what I think the Brown rust is.
