New Grower Yellowing Leaves and Lightening Leaves

[ElCh4po]

-Problem: Leaves began to yellow and get brown spots along with a neon green color on all the other leaves in a matter of days after a 1/8 strength feeding of Tiger Bloom along with 1/4 Big Bloom during week 5.
-Medium/grow method: OF 3gal Fabric Pots
-Feed and supplements used: Trio, CalMag, Bio Root. Started with Grow Big around week 4 at 1/4 strength. CalMag at 1/2 strength with one of the plain watering days, Bio Root with the other plain water day. Feed/water/water
-Water source: Well water pH to 6.4-6.6
-Strain and age MSNL Auto GDP end of week 6 starting 7.
-Climate: Day 76/Night 72 42-50% Rh
- Light used: Mars Hydro TS 3000 LED 20/4 20” above canopy. In 4x4 tent
-Additional info: Its been a week since Tiger Bloom was fed and the signs began showing 3 days ago. I have Sledgehammer and was wondering if it should be used to flush because the salts may be causing nutrient lockout? Its affecting the biggest one of the tent which has not shown any issues until now.

Are you familiar with a process a plant undergoes called senescence? The quick definition is that it is a part of the aging process of the plant. Looking at your photos your plant has a ton of leaves. With my plants I watch them thin out the leaves on their own and as they are yellowing they are feeding their sugars to the plant before they die. I leave them on until they'll come off with a flick of a fingertip. I don't pull them off.

If you are looking at your plant to run 10 weeks or thereabouts I feel confident saying you do not have an issue just natural plant aging as it moves into the autumn of it's life.

However, that said I always recommend you don't take the word of any one individual and run with it. See what others have to say and make your best decision based on the information you receive.
