Day 19 flower deficiencies! Please help

[Gward20]

I have 8 zurple punch plants in flower and they started getting deficiencies about a week ago. I gave each plant between 10 - 20 litres each of their feed at a Ec of 1.6 and ph 5.8 about 2 days ago and they seem to be getting worse. Please could somebody help me sort them out! Thanks

Whats your background ec?
What nutes have you been feeding prior and what they on now?

Look a bit hungry to me, its a hungry time your at aswel

your dope aint defficent bach its burnt !!! to much ferts to early my advice is to leach the pots out with fresh ph`d water twice the volume per pot size of water ph @ 6....leave them dry 1 day and feed them a much lower cf/ec say 1 c.f.... 1.0 e.c .......by feeding such a high cf / ec at this plant stage is way to stong, + btw why are ewe watering every few days ewe should be watering the dope daily imho

Hi mate thanks for getting back to me.
Yes I’m in coco, my temps are around 29*c constant and around 18*c of a night.
My background Ec is 0.2.
I’m feeding (40 litre mix) 10ml buddhas tree solar green silicon, 10ml calmag, 20ml pk 13/14 & 80ml canna a + b. Ec 1.6 ph 5.8.
Last week I gave them 2 feeds using super bud reborn to help with the stretch.

Thank you.

A couple things - Are you using coco or soil?

Either way, I'd raise my Ph input. If coco, for now, go with 6.3 and then taper down to 6.1 after a week or so. If you are in soil, raise it to 6.3 and then gradually bump it up to 6.7 Ph.

It also looks like it may be staying too wet in the lower root zone, which can cause Ph fluctuations. How often do you water, do you water to run-off each time?

How about your humidity and average temp? Do you have a fan blowing a heavy, direct wind onto that location?

Hi mate, I’m using coco. I usually feed around 5.8. When I gave my plants 10-20litres feed a few days ago to flush them out, the run off Ec was the same as I was feeding but the ph stayed around 6.2-6.3.
I agree with you that at the bottom of my root zone is staying too wet because the tops looks bone dry but the pots are still heavy. I water every 2-3 day and split a 40litre reservoir between the 8 plants through a drip system and yes I get lots of run off.
My humidity is normally always between 50-60% and my fan is blowing just above the canopy.

Thanks for helping

Hi mate. I’m using 20 litre airpots and I don’t have a clue what my root zone temperature is sorry. My canopy temperature is around 29*c.
Thanks

You are a genius! I would never of guessed it is nutrient burn. My thoughts was potassium and magnesium .
So I should give each plant 40 litres of water ph’d to 6.0, then the next day give them a feed of canna pk 13/14, canna A&B to a Ec of 1.0.
How long should I keep the Ec at 1.0 for ? Every other grow I have done I have used a Ec of 1.6 in flower and it’s worked a treat. Thank you so much for the advice
