Is itToo Early for This?

Today is 38 days in the hut under 600hps. Started as clone, orange crush strain.
Watering with Foxfarm Big Bloom and Tiger Bloom, according to their directions. Ph is 6.4. I understand some yellowing, but this much? What happened?
Look at the buds, they appear fine, but not all that big and are turning orange.
Should I stop feeding at this point? Harvest time?
Looks meager at this point, I'm bummed.
The leaves look scary!

Fortunately I have a new grow underway. Sour Diesel, 2 wks in the hut, 3 ft. tall, flowering, looking lovely. Wish me luck on that one.

Thanks in advance

38 days???? that seems a lil early for that much yellowing, but I dont know much about that strain, could just be normal finishing for her...... the bud looks good though. Keep us posted on her.

Looks like a mag deficiency to me. Have you given her any epsom salt?

Gave them epsom salt last night with the regular feed.

1/2 Tbls for each half gal.

with your next grow you should incorporate some form of micro nutreints that would help blackstrap mollassas works good too

Looks like Phosphorus deficiency, Pic and text taken from ICMAG

Solution to fixing a Phosphorus deficiency
Some deficiency during flowering is normal, but too much shouldn't be tolerated. Any chemical or organic fertilizers that have Phosphorus in them will fix a Phosphorus deficiency. If you have a phosphorus deficiency you should use any N-P-K ratio that is over 5.Again Peters all purpose 20-20-20 is a good mix. Miracle grow Tomato plant food, Miracle grow All purpose plant food (Only mixing at ½ strength when using chemical nutrients, or it will cause nutrient burn!) Other forms of phosphorus supplements are: Bone meal, which is gradual absorption, I suggest making it into a tea for faster use, where bone/blood meal is slow acting, but when made into a tea it works quicker! Fruit eating bat guano, which is fast absorption, Worm castings, which is gradual absorption, Fish meal, which is medium absorption, Soft Rock Phosphate, which is medium absorption, Jamaican or Indonesian Guano, which is fast absorption. Crabshell, which is slow absorption. Tiger Bloom , which is fast absorption.

Any of these will cure your phosphorus deficiency. Affected leaves will not show recovery but new growth will appear normal.


Now if you added to much chemical ferts and or organics,( which is hard to burn your plants when using organics) You need to Flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.
