help, diagnose my plant!

my plant is about 8weeks just under 3' tall in going ph 5.9-6.0 out going water 6.1 ph.

feeding hydro nutes every other watering. everything going good til yesterday some leaves have purple and leaves curling abit. I thought it was phosphate deficiency so i added a little bloom nutes yesterday.

here's pics

over watering m8.....let the soil get bone dry to where ur plants wilt then water them again....dont water until soil is bone dry!!

Phosphorus - a lack of P causes stunted groth and small smaller leaves; leaves turn bluish-green and blotches often appear. Stems, leaf stems, and main veins turn redish purple starting on the leaf's underside. NOTE: The reddening of the stem and the veins is not always well pronounced. The leaf tips of older leaves turn dark and curl downward. Several affected leaves develop purplish-black necrotic blotches. These leaves later become bronzish-purple, dry, shrivel up, and drop off. Flowering is often delayed, buds are uniformly smaller, and plants become very vulnerable to fungal and insect attack. This is a somewhat common deficiency. To treat this start by lowering the pH to 5.5 -6.5

thanks. im going to start flowering and switch to bloom solution to ad more phosphates and i'll lower the ph a bit.

I concur about the P deficiency but are you growing in soil? if so that ph is prob too low-could be causing lockout of p.

i keep my ph around 5.8 - 6. that shouldn't be too low? i'm growing in peatmoss, perlite and vermiculite

plant has gotten worse, here is a pick, still think its phosphates? what doi do? helpppp

starting to look like a k deficiency. raise ur ph a bit. may want to flush and feed at 1/2 strength
