Help!! Need opinions

[staysmokin]

Hi ive currently got a plant that looks like could be showing signs of some sort of stress. Im running mars hydro fce 6500 bar light with 5g pots of coco loco. I use foxfarm cuktivation nutrients water ph to 5.8-6.2 temps usually 70-72 humidity 55-60% . Cant decide if its light stress or what. i have light at 50% and it is atleast 30" above the tent. The plant shows purplish stems towards the top of plant not so much on bottom. Cant tell if its genetic strain is supposed to bad apple. It looks like could also be a.deficiency maybe im locking something out. Excuse the mess i just finished defoliating and didnt clean up yet before taking the pics. . Any help would be appreciated.

No i feed every other watering and water ever two days. Should i feed more often you think?

The plant looks a little over fed. Dial back the dose a little and try keeping the ph at 6.5

You need to feed to runoff every day.. Your coco has salt build up, causing lockout..

You think its drying out between watering causing salt to build up?

Should we use nutrients every day?

If you want to grow in coco, use unamended coco. Cultivation Nation is 70/30 coco/perlite; Coco Loco is amended with fertilizers, so you need to give it like 3-4 weeks before you start adding bottled nutrients or reamending.

These have been in the pots for more than a month they have been vegging for two months or so

needs food, specifically K. The burned tips and light green edges is textbook

I was thinking magnanese due to it being new growth and interveinial chlorosis?

 

[ec121]

What EC are you feeding at? What is the EC of the runoff? Figure out the answers to those two questions and you'll figure out what the issue likely is and how to rectify it.

Get something like the Photone app for iOS to measure your PPFD so you can get a good enough ballpark and not guess.

Raise temps and give it more light.
