yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10

bobo66started grow question 2 years ago

This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!

This has nothing to do with nutrients. The plant is suffering from heatstres. She is probably the closest to the lamp. The heat from the lamp is causing leaves to take the shape of a taco to prevent that they dry out. Move the lamp further away and she will recover within a few days.

I agree with GMSgrows. I even would add that keep ph 6.2-6.4 all cycle for first experiences with coco.

I wouldn't worry to much towards the end of flower. Try keeping your ph at 6.2 to 6.3 through flower and provide a little grow with your flower nutes and keep an eye on your ec levels creeping up in the planter..

according to the table, pure zym should be left at the 3rd week of flowering, which is what I did. Maybe it should be given once a week? and in Cocous. Do you have to add the nutrients with every watering or can you incorporate a clean water irrigation as well?

Do you have a diary for this grow? That would be most helpful to us...

It's been a week since I switched to flowering and new growth on the plant all has a yellow/lime green colour but this seems to go away when the leaves fully grow out and growth in general has not slowed down. Based on the pictures in my diary should I be concerned?

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

Guys what’s the opinion on flawless finish for flushing. I have read on many forum sites that it does not do anything does anyone have any experience with such a solution. I have used it for the first week to flush the plants and I will use it for two days of the second week.

Do you see nutrient burn? I'm guessing (after some forum assistance) they are underwatered. Shame on me! So nutrient burn or underwatered?

Dear ganja gurus, please have a look at my diary Wk17 D119. I'm thinking nute lockout due to pH always below 5.8. But any other inputs is most welcome. Nute is 50 ppm epsom, 100ppm CaNO3, 100 ppm MKP, and topped with 7-5-16 A/B to 900ppm.

Lower two sets of fan leaves have gone yellow, leaves on internodes in between haven't changed colour. Not sure what's causing this. Nutes? (3-4 more weeks of time released nutes in soil) Too much water? Did water a bit extra because I wasn't going to be home for a couple of days

I have tried to figure out what this could be without much luck... it seems that my leaves are having a slightly yellow tint to them under the grow light. Under normal light it seems ok, what could this be? Overwatering I am guessing but not sure.. Any help would be appreciated

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!

So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!
