Stunted Plant Growth!

My Tahoe OG has completely slowed down. The leaves are looking very curled, and are growing very slowly. Any ideas why the growth has slowed and the leaves look so funky?

5 gallon pots

Temps 68 High 61 Low

Drip Feed Coco

Looks like possibly a zinc deficiency.

Deficiencies appear as chlorosis in the inter-veinal areas of new leaves producing a banding appearance as seen in figure 18. This may be accompany reduction of leaf size and a shortening between internodes. Leaf margins are often distorted or wrinkled. Branch terminals of fruit will die back in severe cases.
Also gets locked out due to high pH. Zn, Fe, and Mn deficiencies often occur together, and are usually from a high pH. Don't overdo the micro-nutrients, lower the pH if that's the problem so the nutrients become available. Foliar feed if the plant looks real bad. Use chelated zinc. Zinc deficiency produces "little leaf" in many species, especially woody ones; the younger leaves are distinctly smaller than normal. Zinc defeciency may also produce "rosetting"; the stem fails to elongate behind the growing tip, so that the terminal leaves become tightly bunched.

Very def in N,P and Mg because the ph is way out, make sure all feeds and waterings are 6.5.

on pic 3 on the right of pic ii see purple veins thats generaly mag deficency to me if not in your nutes put it in there ,if its in there flush your plants nutes lock out and also the temp should be 76 degrees .
