Not sure what the prob is

So I thought this grow was going pretty well… until I woke up this morning to this

Almost looks like a calcium prob so I added cal mag … then upon looking it also looks like a phosphorus
I am growing in coco with advanced nutrients and in week 5 of flower… I am also using a high NPK so confuses me if it is phosphorus…

The only major change I have made in the past week was… Moved all my stuff from a 4x4 tent to a 8x4 tent cuz I ran out of room… While in the 4x4 tent I ran a constant 77 degrees now in my 8x4 I am running about 82-83 … will add another fan later today to help with that… and my ph is 5.7

Strain; Autoflower

Soil in pots, Hydroponic, or Coco? Coco

System type? Grow Tent

PH of runoff or solution in reservoir? 5.7

Indoor or Outdoor Indoor

Light system, size? 2 600w HPS

Temps; Day, Night 82-84 will fix later today to bring that down

Humidity; Day, Night 50%

Ventilation system; Yes, No, Size Yes, 6" extraction fan adding another later

@Donaldj @Majiktoker any advice? Was told ya got smarts with deficiencies …this is my first grow and I just ordered ILGM seed yest so need to get this right before I try those!

What is the nitrogen content my first thought was to much nitrogen and a lack of phosphorus and potassium


Im sorry I ment a high PK minus the N … I am using advanced nutrients coco bloom A & B and FF Beastie Bloomz which has a 0-50-30 NPK

Might be to much being said is this an Autoflower plant

Yes autoflower … I have 9 plants total in same tent all started same time… This is the only one this is happening to … I do have 2 that look heat stressed which I will attempt to fix later…This one here tho is also my smallest plant where the rest are lots bigger, hell, I have one that is over 4 foot tall lol

I think she might be over fed being said shes an Autoflower, Autoflower dont need much food for their grow cycle, cut back on feeding for about a week and see what happens also maybe get a reading of your runoff that may shed some light on the situation at hand


Ok, thanks Maji… I will give that a try :slight_smile:

@Majiktoker took pretty much every question and suggestion out of my mouth lmao
I am curious about your humidity the higher temps will have triggered faster feeding/drinking and a reduced RH from larger space would make that even more excellerated. Hooking and clawing are usually N related or climate :wink:

@Donaldj My humdity is about 45% … thats what it is right now…and stays around that pretty much… never seen it higher then 50…still working on getting my temps down while I work on getting another inline fan or a larger one… got temp down to 80 from 84 so far
